Don't worry, If it makes you feel better. I've dealt with the same issue and your plants look better then mine. lol. If you get a chance, head over and check out my grow.
Between 70-80 lately. If you are wondering, I was fighting a losing battle to high heat low RH for awhile, didn't know how bad it could/would damage my plants.....What are your temperatures at?
Twas only $10 so hopefully it works out, I've never used anything outside of MG so - if it's half decent I will notice the results.Sounds similar to Advanced Nutes Nirvana.
