Thanks for the help guys, so I'm about to do a res change, I will give you a rundown of what my stats are.
I'm growing in coco claypebbles 60/40 mix
I'm running a flood and drain system, I never let the coco dry out always kept watered regular as I had problems when letting dry back.
Temps 26°c
Humidity 50%
Currently put in flower 2days ago because I'm moving over to a RDWC system next.
Canna a+b coco feed, adding vitalink
calmag too, I was thinking of upping the
calmag hence this question.
Ph is at 5.8-6.1 drifting between.
EC is 1.0 but keeps rising and then stays at 1.1-1.2 so maybe a lockout?
By the way there are no bugs at all.
My stems seem to have gone really purple at the top, this always happens every single time, I have began to think that maybe they get rootbound in the 10.5litre pots they are in? The problems occur just before I introduce them to flower like really purple stems from the top, I did give them a foliar of epsom salt around 5days ago but no change. I will attach a photo. Thanks
