I can't find it in the pictures of any deficiency threads.


Hand water coco in small tent

Wilma system in big tent (hydroton/stones).


Temps have been 24-31 (hot summer)
RH 45-60%
plants are 2 weeks 12/12
PH 6.1-5.5
ec 1.6
Background ec 0.7




This happened on my last grow too (my first) It stunts them from growing colas all I got last time was pop corn bud all over, no colas at all. always seems to happen just after I switch to 12/12




It gets much worst later, this is my bigger tent.



Ive tried calmag on my last grow but that's not the problem, any ideas. I'm baffled

i am confused, looks like a lot of plant matter, try cutting some back to give it more light penetration. What type of lights are you using? and kind of nutrients?

Your pH is too low for Coco. Switch it to 6.2-6.4

Hand watered coco? Don't let that coco dry out as much as you'd allow in soil. It should always be moist. When coco dries the salts become concentrated and pH drops radically giving you lock-out.

Use large low power magnifying glass to do close root inspection for Root Aphids. Do it in good light, and be quick because they will quickly retreat into medium. Also observe color and overall health of roots. Keep us informed. Good luck. -granger
