Root rot yellow center ?

Not sure what’s going on but the middle leaves are starting to turn yellow and some have brown hairs on the new growth ? Is that root rot ?

If you are relying on the soil for the food then perhaps it is exhausted? Tell us more about your soil, feed...

I got a organic 420 soil my feed I have is a growth formula will have to look at the exact name of it tomorrow . But I usually do a table spoon to one gallon of water and I feed it about 8 oz of nutrient

in one gallon pots outdoors . Right now started them off from seed back in first week of March

Hmm, not sure what the PPM or pH would happen to be are you?

I suspect your pH may be off but without some means of checking you are flying blind.
