I grow in a mix of recycled soil, amended after each grow with KIS Organics Nutrient Pack. Water only from veg through flower. I’ve had great success with this for a while now and it’s perfect for my lazy approach. I don’t test for pH. I just leave tap water out to de-chlorinate for a couple days before using.
Every once and a while I run into this banding issue during veg. It seems to start on the middle older fan leaves. New growth usually looks good. And it seems to grow out of it as the fans get older. Almost like the dark green vein parts slowly take over the whole leaf.
I never gave it much attention because the plants always seem healthy and vigorous, and it’s usually only a couple plants. This newest grow seems to be affecting almost all of them. You can see lots of leaves in various stages of transition. In another week or two there might not be much banding left, and the leaves will be considerably darker.
I’ve heard that if the soil mix is too rich for young plants they can react this way. I’d love to hear what others think. I’m thinking maybe that and maybe light intensity is too strong. I also am concerned that I added too much dolomite lime in the last mix, if that’s a concern.
Thanks for any ideas. FYI pictured here are 3 50State Orange Goji, 4 Eskobar Chocolate Rain, and 5 Death Stomper (Death Star x Grape Stomper OG). The Death Stompers have the condition the worst.
