FIRST GROW - HLG550 - Bubblelicious

Week 4 and things are getting a bit more serious now. The growth is exploding. I topped 3 of the 4 main plants, leaving 1 un-topped to see the difference in yield and growth. I did some LST on unwieldy branches to even out the canopy. By the end of the week I started mixing 'pre-flower' fertilizer, just below half strength but it was definitely too much for the plants. They were droopy as heck, and new growth was twisted and shrivelled. Big oopsie. Out of the 5 plants, 3 were showing pistils. B#3 and #4 seem to be stubborn. The Jock Horror seems to be a lost cause at this point. Too scared to pot it up or do any training with it. Will keep it going, maybe it'll yield half a gram. Lights are 20/4 and pH is still at 6.5.
