You need to know your pH! This is a plain and simple fact, and arguments/excuses aren't going to change that. If you can't afford a pH meter, get a liquid test kit or litmus paper.

I'm going to have this thread moved over to "Plant Problems". You'll probably get more and better answers to your questions there.

PharmaCan Reviewed by PharmaCan on . NEED HELP DIAGNOSING PROBLEM!!! PICS So i have this reoccurring problem with the last couple grow attempts. I use Earth Juice Grow, Calmag, and Superthrive for veg with 2 tsps of high nitrogen bat guano. I use FFOF soil and I use RO water. I dont have a ph meter but I water them with plain water every other time. Temps are between 69-76. Any advice? :( Rating: 5
