busteruk7 Reviewed by busteruk7 on . Trouble with my plants... please help! So these babies are 15 days in veg. But some of them has yellow spots on their leaves. The soil is some peat moss mix, with sand, etc + I guess there are some ferts added, because I see little fert balls. pH is 6.8-6.9 for soil and the same for water I use. You can see the yellow spots in pics: 1.-5. The yellow spots are on new leaves too, even more. Pots are 4 gallon with few holes in the bottom. Even though pots are pretty big there are some roots sticking out of these holes... So this is Rating: 5
