Hi, during the vegetative stage, don't raise the EC above 1000; they seem to be saturated with nutrients. The recommended level is 900. I use Biobizz, and with the biogrow, I use 50% of the dose, 1 ml per liter, and for the rest of the additives, I use everything. Try to raise the humidity to 65% and control the height of the lamp. Good luck, and I hope this helps. If you have rooting hormone, use it foliar when the lights turn on.
