It kind of looks like a sulfur deficiency. What is your pH?
@ FailMore Snap! I think you may right Failmore, Only the new growth is bright yellow
that link has some solutions also i believe.
Ph too high for coco. 5.8 -6.06.0-6.5
the grow medium is coco
Nutrient is RAW Grow (All in one)
Yeah... I was completely wrong. I'm apologize for the wrong info.
I swear everyone single plant problem post is a guessing game. NO ONE actually knows whats wrong with the plant and cannot tell you. ALL deficiencies mimic each other lol. I think once you have a an issue, you're fucked lol. You will chase your tail for the rest of the grow wondering, tinkering and ultimately fuck it up worse, well for shitty growers like me anyway lol. Maybe if you have insane experience you have a shot at correcting. Yours don't look too bad, best of luck.
Ph too high for coco. 5.8 -6.0
SH420
it kind of just looks like vigorous growth to me....don't worry about new growth being pale green as it grows in, unless it stays that way...
i would adjust my ph to 6.1 for coco, and up my feeding slightly, maybe 10 %....otherwise i don't really think you have a problem....
let us know if it gets better,i have the same issue.calmag helped a little in my case.currently lowering nutes and ph.good luck.
There is nothing wrong with your plant
