Looks like they show signs of nutrient burn doing 1/2 tsp or more of complete crop. Each strain seems to differ in how much before the tips start to show burn. I'll stick to 3/8 tsp for the remainder of the grow and use the 1/8 tsp flower fuel as I have always had good results with that amount. Seems like the canopy is evening out now and I can raise the light without leaving any plants to suffer. They are dropping/I am pruning their bottom leaves every few days and seem to be adjusting to the space well. High hopes for this harvest.
Going to do one big defoliation soon to remove lower foliage that won't develop and expose bud sites by thinning the canopy. I feel like constantly chopping a few leaves at a time makes them stunted.
