Well...
I have some of those taller ones growing into and past my lights. I started them in flower at 6-8 inches and now there 36+. The tops that are into the lights are getting crispy leaves. I was hoping for a more even canopy. I have two lights to compensate for different lengths but this was well beyond what I expected.
This situation also makes it difficult to keep a nice breeze on the tops to combat mold and high humidity. It looks like everything will finish fine.
On another note I have been feeding 5.5 gr/gal of MegaCrop with 1 gr/gal each of sweet candy and bud explosion. Some tubes started this feeding right at day 21. At this ppm its been cruising so far with no issues. I fed today with a little more MC at 6 gr/gal
