yellowing leaves ca/mg or n def?

[smokefx]

hey guys, heres some pics of what im looking at. they were fine in my veg tent but when i took them out to a bigger room they turned yellow and a little droopy but only some of them. i'm using gold label special mix coco (usually use canna but they ran out) currently running with h3ad formula 6/9 micro/bloom with ro water, my ph is set to 5.6.

should i be using ca/mag or am igetting N def? thanks

ps: only around 10 of them are yelling the 3rd one in the pic is one that didnt get effected the rest are yellowing out as you see

calmag would do both it has nitrogen

and yes that would be your problem maybe run the ph at 5.8

Temps? I had this happen once, was hot medium and dead roots. Deficiencies can happen because roots die.

Temps are fine 70 to 75 I'll try raising my ph a bit so you guys don't think it's cal mg just low ph locking my ca mg out? Thanks first time in coco

ur ph should be 5.8-6.0 at this stage. you are lacking N, this is a N def.
