I'm having some discoloration in my older larger fan leaves. I'm just wondering what it may be. I use FFOF with fix farm lineup with calmag and AA Big bud.
nutes too strong. flush em and put in weaker solution next time, could be nute locking too, whats your ph at?
if it gets worse it could also be calcium deficiency, take garden lime and add 1 teaspoon to every gallon of water. use organic if you can so it wont burn so easy. but make sure you do a good flush of just r/o water first
