Don't bother with an EC meter. Those are for hydro growers and nerds.
GH liquid pH indicator is SUPER cheap and is adequate for a small soil grower. Less than $10 a bottle.
I'm glad they are feeling better!
stinkyattic Reviewed by stinkyattic 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
