I’m 16 days from flipping to 12/12 and my plants are beginning to flower. I’m noticing just a bit of yellow tips on some of the leaves on my purple kush which is the plant directly under the light, a sf2000. The plants are now 76 days old. I’ve only fed them four times, using half the recommended dose of FF Grow Big and the last feed which was 12 days ago, I added a half dose of Tiger Bloom, ppm 850 (in line with my other feedings). I have included a dose of cal mag with each watering, since I read somewhere that the leds require more of that. Plants look otherwise very good aside from that so I am wondering if maybe too much light? I am right on target with DLI.
The other question I have is about scrogging. The net filled in pretty well though after about a week of flowering I slowed down on the tucking and tying down branches. Yesterday I did a fair bi of trimming to open some of the bud sites that are right at the height of the net. There are things I will do differently next time. Instead of letting the plants grow through the net I’m going to keep them flat under the net (someone on the forum talked about that; and no indica dominant plants. I’m planning to give things another week to let the buds get firmly established and then do a pretty extensive defoliation, and I have another net that I am going to put on to support things. Here’s some pics. Plant of right is Sour Diesel, P. Kush in middle, lemon amnesia on left. All in a mix of FF Ocean Forest, Happy Frog (seedling medium), and perlite.
