This plant's still quite young, so hopefully diagnosing and getting ahead of this issue early will allow it the rest of a healthy flowering cycle. Six days ago, this OG Alien moved from 4 high-output CFLs to a 600W Viparspectra LED. The light hangs about 18-20" above the plant (manual recommends 18" for flowering) but after watching some leaves curl and fold up over the past few days, I've become worried that I'm witnessing light burn. I moved the light up this morning, so there's now about 25" between the light and the top of the plant. I also administered a very light foliar feeding (H20 + CaMg).
I'm thinking that this is also a case of pH too high, locking out Mg, and predisposing the plant to other issues. I use the tie-down method, which could be contributing to stress. Temps average from 22-28°C and wind is definitely not a factor in the problem. Of course, I'm looking to this community for your expertise and advice - maybe someone will see something in this that I haven't thought of. Am I looking at cause for a flush? Last watering went in ~6.3 and runoff was ~7.2.
Growing in soil and feeding organic nutes with a feed/water/water schedule. Blurple photo from yesterday, the rest are from today.
