SEED OR CLONE -seed white widow x big bud
AGE - 5 weeks on Thursday 11th June
HEIGHT - 9.5inches
I’m using 100% canna coco professional plus in a 11 litre plant pot
NUTRIENTS - canna a+b 1.5ml,Rhizotonic 1.5ml,in 2 litres of water. I’m using tap water with an ec of 0.5 so I mix some bottled water with it to bring it down to 0.4
PH NUTRIENT SOLUTION- today was 5.5
PPM/EC NUTRIENT SOLUTION- Today was 0.4
LIGHT - Phlizon 6oo with veg and bloom switch
LIGHT DISTANCE FROM PLANT-5inches from top
SIZE OF GROW TENT- 2ft x 2ft
TEMP+HUMIDITY- 24-26 degrees c 50-52% humidity
After a few days of panicking I went out and bought a blue lab truncheon ec stick today. Basically I’m getting yellow tips on the new growth and a couple of older leaves below only a couple tho, so after reading on other threads I’ve come to the conclusion that it might be Nute burn maybe. So I’ve used my new meter today and tested my run off etc these were my results
I’ve flushed it through with ph’d water going in was ph 5.5-5.6 with an ec of 0.4
My run off read ph 6.5 my ec was 0.8 im thinking the ph is to high, how do I lower the ph in the coco do I keep flushing Until where I want it? I will addd a couple of pics to show what I mean, thanks look forward to your reply’s????????

If you measure your EC going in and keep your pH at 5.8 to 6.2 then all you need to do is get good runoff about 20% of what goes in to come out the bottom every time you water. With the size of those plants you may be able to water every day. From those pictures the plant looks healthy The coloration is good I see the yellow tips, you can get those by feeding a thirsty plant it burns a little bit even though it can utilize the full nutrients you just gave it. Sometimes if I've got a real thirsty plant I'll feed it water first then come back in an hour or two and feed it the nutrients mixed with water.

Hi thanks for the reply, the ph seemed a bit high yesterday 6.5. after I flushed her with ph5.5 water the ec wasn’t to bad 0.8 so today I’ve gave her 1ml a+b 2ml Rhizotonic to an ec value of 0.6 ph value was 5.6 the run off came out at ec 0.7 and ph was 6.4. Do I just keep feeding at this keeping my eye on ec levels and ph’ing the water at 5.5 until the ph drops into the right zone? Or do I keep flushing one after the other with ph’d 5.5 water? which will bring the ec down aswell as the ph levels until the levels are right then put a feed through and leave?

You're way overthinking things for Coco. I know a lot of guys around here swear by measuring runoff but it really isn't necessary in Coco. You want to find a good nutrient level that your plant likes make sure your pH is between 5.8 and 6.2 and water for 20% runoff and forget everything else about measuring your EC or pH of your wastewater.

Those yellow leaf tips probably came about one day when the plants were extra thirsty, and you fed them a nutrient amount that would have been just fine had they not been extra thirsty.

Cheers mate it’s the ADHD in me mate??I start reading things and before I know it it’s 2 hours later and it’s like someone screaming in my head???? I hate it mate, anyway thanks for your reply it was much needed to get my focus back lol?? Would have to be able to read like Jonny 5 (short circuit) to get through all the awesome stuff on here??starting to ramble now lol so thanks again mate much appreciated ????

Perfectly okay to have ADHD, I tend to say the same things over and over so you'll here things enough to catch the gist.

Yeah as jingo said there mate you're over thinking it.
Feed 1ec nutes plus the water.
Feed every day to run off.
Ph5.7--6.3.
Don't keep the ph constant, give it a bit of swing.
Not much else to it really. If you do that you don't really need to know much else cos not much can go wrong.
If the start getting hungry once they're bigger do the sensible thing and go up a bit.
Cocos easy mate the less you worry about it the better.

thanks for the reply guys much appreciated! I'm trying to forget runoff etc and with that in mind,I decided to give it some tic last night and treated it to a hair cut as i've not touched it since I potted it! (will post a couple of pics before and after) ive fed her this morning with 0.7ec ph 5.8 nutrient solution (before I logged in on here lol and read your message) so will up the ec .1 over the next couple of days and see what happens?gonna go start my grow diary today aswell.
