The instructs for FoxFarm say to begin when plants have reached their peak of vegetative growth and are starting to show first signs of flowering. I started it when they reached maturity, but before signs of flower. I agree, I don't think it is that..as Mscaboo said..I didn't continue with the veg nutes, I just stopped them. Temp w\lights on 100, lights off 95. soil is mixed with 40% perlite. lights are 4' flouros,2 above, 2 behind. Thanks for everyones help. Any more ideas are always appreciated. I am going to give them veg ferts for a week or so unless one of you experienced people advice otherwise. all my thanks to you folks. Enjoy your Day.
