first time grower with little/no exp, plants are 3 weeks old, 2 have started to display patches on the leaves. growing in living soil fed bottled water. can anyone help me identify what could be wrong
Grown in 1m x 1m tent, under 315w cdm, day temp 26degrees, night temp 20, effecting 2 different strains, killer glue and melonaid. Humidity is around 50. Growing in sohum living soil
Since it is on the bottommost leaves, I wouldn't worry too much unless it starts to spread to other areas. Damage like you see can be from something spilled on them weeks ago. It doesn't look like bugs or nutrition issues, or overwatered. Keep your eye on it and as long as new growth looks good and the problem isn't getting worse, then relax a little and let it grow. It looks like it is ready for some bigger space to grow into!
