I agree, that Alien OG is looking fire - How long have they (Alien and Chernobyl) been in 12/12? How long did you veg for? I'm trying to make like a timeline to compare my plants to because we have pretty similar set ups (pots, nutes, tent, etc) - You said you got the clones about a month ago (in the first post), so thats approx 1 month veg right there, how much longer did you leave them to veg?
How did the powdery mildew turn out? Luckily I don't have a problem with high humidity (opposite in fact, my RH seems to stay around mid 30s-40s) so I hope I don't run in to that problem but I'm thinking I should maybe hit my plants with some Neem oil because I think I saw a flea or bug in there the other day and I would hate to lose all my plants to pests/bugs.
I just flipped my babies to 12/12 2 weeks ago (just ending week 2 today) and things are looking pretty sweet
