Yellow leaves, spots - First grow - White Russian - CFL
Don't think overwatering is an issue unless the soil is very heavy, thus foliars shouldn't be a problem. Since the soil is peat and perlite, overwatering is going to take some effort. I seriously doubt this is your problem.

You need to be sure your SOIL pH is also appropriate. I go for 6.5-6.7. Usually my water is at 7.3 before adding nutes, and with a lot of peat in the mix this has worked for me on many dif. gardens. The test kit will also tell you if your nuts are out of balance.
Reading your post again, you're watering with a solution in the low 6's, so I still think you have a pH prob., but maybe on the low end and not the high end like I had. I always add lime to my mixes to balance the peat moss.Dorje113 Reviewed by Dorje113 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
