Auto Dwarf Low Flyer

Had to do two dryback period in week 4 and 5 of three days as I was pumping much solution in them with six on/off schedules on the timer and the wet felt pots developped a different smell, maybe the Megacrop smell and or ammonia buildup. The two dryback periods made roots come to the sides of the feltpot interior and resulted in really pronounced growth bursts when the medium had dried for three days although the stretch period is starting today which contributes to the double growth. Pics of Sep25 posted at top show before and after of feeding after first dryback, or the growth after a feed and a dark period follwing three day dryback. Future grows will need more drainage by adding 30% perlite. I lack finesse in my defoliation technique, for this purpose, and the plants being dwarf and autoflowers isn't optimal for training but they are growing nicely with multiple evenly spaced tops. For nutrients this week I will gradually substite PartB (15-0-0) for Bud Explosion PK booster and at some point do a foliar of B-52 and CalMag to wash the stomatas and ready them for big flowering buds. Broken Vivosun zipper, one month of use, locking me out of my veg tent. Amazon not replacing it so not sure what to do but looks like it's coming down.
