    Decided to add some nutrients to my rhizotonic solution as I have the feeling this still can't be nutrient burn. Went with 1/4 strength to see if that stops some of the yellowing/dying. Watered a few days back, posting this for reference to look at later really. If the two big leaves have gotten worse by the next watering I might add another 1/4 strength to try half and see if that helps. Doesn't seem to have made anything worse anyway and it is my seedling solution so low PPM.

    It was funny, as soon as I chopped her top off the two top leaves shot up in the air like she was running around screaming haha. I guess it was just to get some better light angles but I like to imagine... New growth coming along nicely.

    Plan to do a long test of my flood drain system this weekend. It seems like a good way to soak the clay pebbles in a PH'd solution too. It shouldn't matter if I don't plant into them for a month or two yet?

    Hi. Just had a quick read through your diary and im not even going to pretend I understand what nutes you are using but from my angle, she looks nute burnt to buggery....How old is she? I grow mostly auto's in soil and dont use anything but water until at least 4 weeks in. Is she an auto or photo? Ph seems to be an issue for you too but again, that's not something Ive ever had to flaff about with growing in soil and has never been an issue so cant really comment about that but you said she hasnt been watered in 2 weeks? Again,i cant really understand, at this stage i only ever water around the plant very lightly every couple of days. Anyways, hope she pulls through..

    Popped her head up just over 4 weeks ago. Photo G13 Haze from Barney's Farm

    I over watered far too much in the beginning so took nearly 2 weeks to dry out. Still not sure on the PH, been retesting and starts at 7.5 then goes to 8.1 after sitting for 24 hours. If soil is a ph buffer then I don't think it's too much of a problem here.

    For the first 4 weeks I was using water with Canna Rhizotonic added. Only had the first taste of nutrients a few days back. Don't think the soil is too much as the B&Q verve mix is meant to be OK. The leaves seem to be fine for a week and then slowly go yellow. I am not too worried about her dying, just want her to have a happier life.

    Temps are 22-25c and RH 65%

    The nutrients I made up has an NPK ratio around 1:1:2 Potassium is a little high but that's all I could get. Wanted a weak 1:1:1 solution.

    Here is a side by side comparison 3 days on, the big leaves have shrivelled a bit and gone slightly more yellow. I mean the topping went well but still sad about the old growth dying.

    Needs a water either tonight or tomorrow and debating if I should try half strength nutrients. Should see what ec my solution is now but I think it's still pretty low.

    Watered a few days ago, decided to go with half strength nutrients. Seems to have enjoyed it I think, or maybe she was going to have a growth spurt anyway. Added back in the CFL yesterday to try and keep the canopy flatter and give some more light.

    Decided to repot today as I could see roots at the bottom of the pot. Didn't think it through too much as then the bastard didn't fit. Had my first try at supercropping. Seemed vaguely successful.

    Still having a few height issues, keep finding her touching the lights. Decided to tie her down to help. I had hoped to stick in the LED board but that will be a few days yet. Not much happening after the repot and supercrop but I am not surprised.

    Taken about a week to get over the repot and supercrop. Not too bad, starting to get some new growth actually growing (Actually looking back now she is a lot bigger than last week!)



    Still been watering with my seedling solution at 50%. Had a good 500ml water at the repot and another 300ml yesterday so getting much thirstier.

    Seeing how close I can get to these LED's. I did read the ones I am using are intended to be as close as possible to the plant. Hopefully take some cuttings mid to end of September and have a go at hydro. It will be interesting to compare the COB setup I have vs the new board. Never even tried the COBs yet

    Went for a bit more training today, Hopefully let the new side growth catch up with the top height. I am thinking it is better to take clones from there? or the top? or it doesn't really matter?

    Tried the flash with the photo, still looks weird, just different weird. Guess that's just the lights.

    Been experimenting with dimming the driver. Tried to measure the amps but I kept just making a spark and fusing the driver. Luckily it still works.

    Can't remember if I already broke this multimeter testing amps so that's why it's just a short. Probably

    At 26 volts the board/LED's don't even get hot, 30v I would say about 40-50c maybe a warm bath. The full 36v 1.6A I would say 80-90c so still usable but a bit hot. Only designed it to run at 1A. Left it at 26v to see how she grows.

    Had another water yesterday, starting to think I should up my nutrients as still some yellowing. Still, I shouldn't use too much maybe as it's only a mother plant. Going to try full strength seedling solution next water.

    Still amazing how I can chop and bend the plant and it comes back fighting.


    I think we have a contender for first clone. Increased the voltage on the board to 30.5v as the temps are getting close to 20c so want to warm it up a little.

    Wow,glad to see you managed to pull her through! I'd keep an eye on the Nitrogen levels though as it looks like some of the tips are starting to claw a little.

    Project has been on hold a little as it needs to go into stealth mode this weekend. After that I will be taking some clones.

    Been over a week since the last update. She was looking a little sad but gave her a few waters with full strength nutrients and see seemed to thrive on it. Looking much happier. Still some leaves dying but meh, maybe it't just self pruning as the pot isn't too big.

    Had a slight issue with condensation with having the LED on low so needed to turn it up to increase the temperature. Running at about 31v now and solved the problem. Won't be an issue once I can run the extraction.

    So she has started flowering from stealth mode I think. Didn't want a cable running to the cupboard so the light cycle was a bit odd. I think it went On 18, off 6, on 6, off 6, on 12, off 3, on 24 then back to normal. I thought I might get away with it but doesn't seem so. Been back on 18/6 for a few days now. Hard to get a good photo with my phone.

    Anybody think it will be much of an issue being a mother plant? Need to take some clones asap but don't have time until the weekend. Tops are a cm or so from the light.

    I'd double up on this comment by Jumper also mate, looks classic nute burn from the nutes in the soil? Hopefully when roots stretch out she will grow fine.

    Looks like you have a bit of Ndef goin on mate, the skirt leaves have sent all their umph to the newer growth. A little bit of grow nutes should help.


    edit - Another thing for leaf drop like this is lack of light

    Thanks Smoby, I don't think the light is that low. Can't find my calculations now for what the board is but I remember it is somewhere in the middle par range. Not actually measured what it's outputting though but being high in reds I think the lower canopy should be OK.

    I think it may be N def but the problem didn't seem to change when I repotted into fresh soil. I have just upped the nute solution to double strength, need to order some new scales as I broke the old ones so I can measure up some flower nutes.

    Decided (being lazy) to just flower this one. Also the space seems a bit too small for me, I know it is possible to grow 4 plants in there from reading some threads on here but I decided to remove the shelf for now while I finish off this lady. Went to 12/12 properly a few days ago but with the mess up in stealth mode I don't know when to call it 'flowering' but I think she is stretching already.

    Still some yellow leaves but doesn't seem to be progressing as much. Using double strength of my seedling solution atm. Going to order scales this week so I can mix up some flowering solution. Some little buds starting to develop. It's interesting how the node growth was pretty straight in veg and now really angular in flower.

    Board still working

    Just had a nice read through. My last water source was similar to yours. 7.2 out of the tap. 8.4 after it sat for 24 hours.

    While most disagree with me, my grows were all better when I PH'd the water and or feed.

    For plain water, I found that just a few drops of grow nutes would reduce the PH to 6.0. I used grow instead of PH down. For heavy feeds,the nutes reduce my PH to 4. I used PH UP to get it back to 6.
