Ok back from a weekend away and wow the growth has been amazing. All the plants are about 1.5 ft tall with lots of bud sites. I'm starting to wonder if I could safely remove some fan leaves without majorly hurting the plants? I made some changes to the grow box, i removed the bottom tub and have the top tub suspended above to adjust for height and allow me to space them out a little more they were very snug and over lapping with the base. I also put 2 desk lamps on the ground aiming up into the top to give the bottom bud sites more light. So far following the FF feeding schedule has worked perfect no nute burn or lock as far as I can tell. Any comments more than welcome.
