Thank you for taking the time to respond.Those thin leaves with burning edges point toward deficiencies as well, potassium or secondary nutes. What are you feeding ?
Thank you for taking the time to respond.
could be a deficiency. I doubt it would be a lock, I feed daily in coco full remo brand lineup at 3/4 strength. Also over water to ensure flushing since feeding daily. I’m nervous to introduce more nutrients to keep costs down and avoid burn. Maybe I should try full strength for a week? See if the one bounces back. I’ve never had issues even at 1/2 strength…
Thoughts?
Growing in cocoyep some info needed, what kind of lights and how far away are they.,
temp and humidity?
Firstly great reply and info thank you!Been heavy on the calcium perhaps? Mostly I see Mg with a little K. Along with some burn that makes me think lockout.
I'm never keen to blame high light. Often we see problems blamed on light, at half of what a cannabis plant can take. Mg is one of the first things that is often found limiting, and we don't really have co2 deficiency. However, if it's low, processes can't complete. Leading to burn through accumulation of unused components. We will blame high light, but is it? Here I see the edges thickening up, and can't help wondering if that's a mix of high air flow and low co2. Driven in part by the light.
Excess calcium in leaves is often from lower Ca levels. Raising Ca may slow uptake. If the water/plant is warm, and Ca low, with high levels of evaporation, we can see excess Ca uptake. Which shows in Mg and K reduction.
It's a bit mystical, so I will offer a link: https://scienceinhydroponics.com/2019/07/calciums-behavior-in-nutrient-solutions.html
Washboard leaves. Wispy growth tips. Leaf tips veering off. Taco shapes. It's all Mg. We don't have to find stripes. Are you loosing lower leafs in an almost N like fashion?
I must say... plants are not my thing. I like scratching away at topics and do better than many. However it's tech I'm better with. Fixing grow conditions, and washing out the old for new.
Ya know, reading back, you say coco. Coco is loaded with K. I think I'm imagining a K deficiency, and it's just burn. Mg is easy to push out with excess nutes. I generally start with runoff EC when I get issues myself. It's a great gauge. I can't really go on without it.

Runoff ph and tds both within range comparative to inflow levels..I think Flat_Eric put down some good info and I agree with him. Also what’s your runoff EC and ph? I have had similar issues from both mg and ph of runoff was way off meaning the ph of coco was out of range not allowing the roots to uptake some nutrients. The runoff will help lead you to the problem.
nothing better to do eh pal? Way to shit on somebody while their down.its your first crop still.
hey, i’ve never grown with coco so my advice could be wrong,Runoff ph and tds both within range comparative to inflow levels..
really stumped here guys time to feed and no clear path forward lol.
lights are at a good height
nutrients going in are the same on the way out same with PH (minor fluctuations)
I feel like maybe my 3/4 of recommended dosage is lacking? Just wouldn’t make sense since the other three plants one of the same genetics even are flourishing..
@Aqua Man ?
@GNick55 ?
