I am only responding because I LOVE your user name!!! LOL
OK, and I grow tomatoes using a top
drip system with great results, but...outdoors. I also use a G.H. Flora product...FloraMato for flowering not for vegetative. FloraGrow is Veg only right?
What Flora series are (or where) you using? And/or what are your Veg.
nutrients, what are your flower nutrients?
I am not familiar with KoolBloom, is that your flowering
nutrient?
What P.H. are you running? My P.h. I try and keep 5.8-6.5, I am constantly pushing it down...daily almost.
What substrate are you using? An hour on, hour off seams a bit much unless you are running a Less-absorbent media. Are you running Hydroton (sp?) The clay pellet thingies?
Personally I run Perlite, 3 minutes on every hour, during daylight hours only, the commercial growers run on the half hour. (My buckets also contain a small res. on the bottom to whick up to the roots ((pretty sure that keeps them alive at night ;-)))
What are we looking at with your lighting? Watts? Type? Spectrum? Age of
bulbs? Oh, and light height. Do your plants look leggy at all?
Any flowers yet? You should have flowers by now. I am running outdoors pure vegetative nutrients (supercharged) with about 14 hours of light, and not only flowering but producing fruit as well. I need to switch to my flowering nutrient but I am waiting for my pepper plants to catch up.
Fill in some of those blanks, and some of us might get a better idea of what might be going on. Pictures?
