    ph has been rising very slightly and ec is either staying static or dropping slightly. i've given them 10ml pk13/14. this is my first grow and going by what i'm finding online the closest symptoms I can see is potassium deficiency. other than this they look good even if too fkn tall.

    Yeah so they are eating fine, the crispy ends does look most likely to be potassium def. A bit earlier than usual to see this but it could be a strain trait. Canna aqua usually on point until the buds start to cluster then advised to use pk13/14 (around week 3 of true flower). No harm in giving it early though just be careful as it’s really strong stuff. All the best

    thanks mate. yeah everything seems good apart from this atm(and the size of them).I looked online re the pk and the makers say you can use it in smaller quantities all throygh flower so i've tried that.will post the results if anything happens.btw when you say bit early to see this? when do you usually see this?

    The plants typically need more potassium and phosphorus after 3-4 weeks flowering, hence the recommendation to use a pk booster at this point. Usually the aqua nutes give enough up until then but possible they may need a boost before. As I say it could be a strain trait.

    What you could do is cut the tips off that are crispy and keep a look out for any more appearing. That way you’ll know if the boost has worked or not. I think you’ll be good now though

    As the Pk was only added recently I’d give it a good 24hrs before expecting to see a noticeable change. Once you’ve cut all affected parts off you’ll get a good idea the day after if there’s still a problem.

    I see your using clay pebbles, is it just clay pebbles or is there another type of medium with the clay pebbles?

    You said it was rockwool in an earlier post, I presume they were in smaller rockwool cubes then transplanted in to clay pebbles?

    If it’s this method your using I’d have them running 24/7. That’s how I’ve always used a Wilma system and it’s worked great for me every time.

    I noticed you had taken a pot/pots out the system.. Try to avoid this pal as I’d expect to start seeing roots out the bottom of the pots at this stage and you could stress your plants doing this, especially if the roots find their way to the res tank (which they usually always do).

    When taking pics, open up your tent a couple of mins before lights come on and take a few from a distance if you can to get an overall view and up close of what parts are still affected after cutting the previously affected parts off. If you cut them off today try to get the pictures just before light on tomorrow.

    If it’s really noticeable even after cutting tho’s parts off before the next day then let me know, with some pictures if possible please. All the best

    hey nuggetz may thanks for your great advice. only clay pebbles and have them running 24/7 so all good there.was a little worried about that and yes they were in small cubes then put in 4inch blocks and into the pebbles.i have taken plants out of system to move them around and trim them.i'm in my attic and really have very little room to manouver, il stop doing this.
    i'l cut off the affected areas tonight when light goes on and see from there.cheers again.

    No problem pal, just out of interest is it the blue or black drippers/flooders your using? And also where are they within the pots?

    its the blue drippers and I have them stuck into the rockwool blocks kinda central to main stalk. as first grows go this is the only prob I've had in nearly 7 weeks.they are really too tall and i'd take them out the tent if I thought I could get away with the smell in the next few weeks. I don't think conditions would alter too much outside the tent. I've bought an oil heater and a heat mat just in case. it's really the aroma i'm afraid of tbh.i have a decent ext fan and filter,do you think that would take care of this in a small attic?

    Okay, all good there then. You've done a good job so far, can see your plants have been well looked after, just a minor issue to sort out at the moment. If height is becoming an issue and your seeing heat stress/ burnt tops, try tying them down. Failing that you could use a method called supercropping. Although not ideal as it's considered high stress training, your early enough in the flowering stage to do it without any major issues. For your next grow look into topping and lst'ing, this will keep the height of your plants down and help achieve a better yield.

    If your attic isn't air tight sealed then the smell during the later stages of flowering would escape and with your plants being a cheese variant it wouldn't take long for your neighbours to get a whiff of it. Keep them in the tent with the extractor and filter and you'll have no problems with the smell mate.

    i'm in trouble with the size these are getting. it will be 3 weeks into flower on sunday coming.if they get any bigger( and it looks like they will) they're gonna go through my lamp.i'l try tying back and bending them over tonight when my lamp goes on. if that doesn't work i'l need to take them out of tent and maybe get another fan/filter.Click image for larger version.

    Unless your loft space is sealed another fan/ filter won’t help you pal. If I was in your shoes I would just super crop the nearest branches to the light. Yes it will stress them for 2-3 days but I’d take that over constant stress from burning under the light.

    It’s not too difficult, just watch a couple of videos on how to do it and don’t be shy or hesitant as you bend the branches, as long as you follow the instructions you shouldn’t snap any.

    If your going to do it I’d suggest doing it asap as the earlier into flower you do it the longer they have to recover and to fill out. All the best

    They look great other than the height, have you noticed any other crispy/yellow leafs?

    Okay you shouldn’t be opening your tent before lights on. 5 mins before maximum, that gives enough time to get some pictures. You want to stick to that 12/12 routine best you can to avoid stressing them. Too much stress might cause them to hermie (throw out male parts and pollinate your crop)
