Well I been left the challenge lol , mine was a male seed that produced all seeds soooo . CHOPPED ! I use LED's And Use Limestone Or Dolomite Lime In The Soil Not Only Does It Add Cal But It Also Adjusts Ph , And That Works Fine If I See A Mag Def Which I Haven't I Use Epsom Salt Spray
I would not spray your plant even with water when it is on flowering mode , if anything I'll spray around the area the air , the fan leaves but that's right before the light goes off. Cause bud rot can def form .
Well I use ProMix the red Kind with limestone and etc . And I don't feed Nutes until about 3-4 weeks or really until I feel the plant is asking for some or pistils start to form then I'll start flower Nutes with the beginning dose of growth .
