Growing with leds requires a lot of knowledge on the light spectrums. If you dont use enough blue light in veg you will never achieve good results. You wont get good results using only 90w ufo, try adding a 8 socket satelite light rack so you can play a little with spectrum buy adding other blue lights to the setup.
