First-time grower here. About a month ago, I switched to 12/12 and now my leaves are starting to turn yellow around the bottom and get a different shade of green in the middle. Some of the well-colored leaves look “burnt” around the edges. I can’t tell if I’m overwatering, under adding nutrients, have a nitrogen deficiency, or something else. The uppermost leaves seem pointed towards the light like they are doing well, but it seems a bit too early for all the leaves to be yellowing to me. Any advice is appreciated. I will try to post some pictures if I can figure it out.
I read that the older leaves start to die in flower, but the middle of the plant appears to be losing some green as well, so I got nervous.
Soil was made of Promix garden soil with 65% peat, I added vermiculite, perlite, and earthworm castings. I’m watering every 3 days about 48 oz. very little run off with some dynagrow 3-12-6 right now. PH going in is right around 7 and TDS is pretty low. I don’t know about outgoing water.
