Grow #3 Purple Kush

We’ll end of week 4, Day 28 and all is going well. I gave them one feeding of 680PPM and had the slightest of tip burn on PK1, so I flushed with 500PPM which they seem to be doing fine with. All is well, just a slight slow down in growth due to mid week defoliation, but they are bouncing back nicely now. I started to do some LST earlier in the week, but have since removed it. Going to just top all the tops in week 5 and send to flower in week 6. Any comments or suggestions? Mid-Week 5 Day 33, Topped all tops and defoliated. Getting ready for flower, flipping the switch in 10 days. I know they look bare, but they will be fine 😎 a few hours later and they were reaching for the lights !
