Light, air, everything is fine. They have 3 1200w light panels in a 2x4 space. What your seeing is the aftermath of a PH problem. One water supply was supplying 8.2, while the other was supplying 4.6. Three days ago most of the plants looked like the yellow ones. Most are green, and the few with the brown edges, is nute burn caused by me accidentally using wrong sprayer that is nutrient based. I Keep 2 sprayers. One with nutrients, other plain h20 but with peroxide mixed in. The plants you see that are yellow, were the ones that were almost dead. They also seem different from my other plants as the leafs are more thicker than my others. Plant 14 Pinapple Kush, Plant 16 Pinapple Kush, Plant 23 Neville Haze, and Plant 10 Big Bud auto are the remainder of the 26 plants to recuperate from Disaster. Before I even found out the PH was way off, some other matters happened, like thermostat breaking and killing 48 seedlings as the seeds got cooked, Then there was an issue with some seed strains, Purple Hulk, Sour Grape, AK47, and White Widdow Max. Those 4 even after the PH and heat issue fix wouldn't germinate, and the few that did died. I thought it was me, but turned out the seller actually had an issue and gave me over 100 free seeds to make up for it. So even though I did kill over $600 in seeds, I'm not complaining because the seller at least made good on his part and I'm still way ahead in seeds. The only one that I'm giving main priority to is my Girl Scout Cookie. With the free seeds, he gave me 2 and I grew only one just in case and it is extremely strong. It survived the heat, the PH issue, the watering issue, and not once got sick. Whoever made this strain, did an awesome job. I want to start training my regular plants. The autos, not sure if they can be trained.
I was starting to train some plants when I noticed something strange, strange because I been running lights 24/7 since I started and noticed several plants had buds that shouldn't have unless I had switched to shorter lighting or they were autos too. As it turned out, the seller sent me autos on my Pineapple Kush that was not supposed to be Auto so after looking at the space and realizing that I have other plants needing transfer to pots shortly, I would end up with a complete mess before 3 weeks from now so halted the training part until the plants get taller, and I get my new grow room large enough for everything.
