He said he uses a soilless mix. (with added perlite...?) Usually that means a peat-based mix, which most contain buffers added by the manufacturers. Were he growing in straight peat with added perlite, I might entertain the possibility. Most all of the potting mixes I've tried are buffered to near neutral ph, (6.6 to 7ish) so no... I do not think it's a ph problem. No way he could have burned-through the buffers already, and it looks like overwatering. And yes...even with additional perlite, you can oversaturate.
Rusty Trichome Reviewed by Rusty Trichome on . Yellow leaves, spots - First grow - White Russian - CFL I did some googling prior to this, but honestly I can't nail it down. I beleive the issue started after last feeding (4 days ago). This White Russian is a clone I gotten a month prior. Its transplanted into soil 16 days ago. While it went well it took a few days for yellowing to disappear. About 3 days ago it showed up again. At first it started in middle (I think) and only effected the lower and middle leaves. One is yellow, probably canary yellow, and some dark almost red spoting on edges Rating: 5
