Anyone know what may be going on here? Started just before I started nutrients. Although I had started CalMag at 1 ml. Also transplanted a week before. Using Ocean Forrest and Spider Farmer 2000 at 24”. Tried to calm my self but it seems to be spreading.

Could just be the soil you transplanted in was a little “hot” and it’s showing signs of nutrient burn. I would just go plain water ph’d for a few days. No nutes for now let it feed off the new soil.

I was wondering that for awhile. Transitioned from Happy Frog to 1/2 HP 1/2 Ocean Forest to straight up OF. It was on just the one plant. After there first feed 1/4 the amount called for of Fox Farm Big Bloom they showed a big growth spurt.
So I guess on the one plant I will back off for a few waterings. So hard to be patient, they have their schedule and I have mine.

Both those soils have lots of heat in them but they're great if the plant doesn't burn up when it's young. Hard on small autos. How big are your plants? Those fans are all super green, so it sure looks like nutes.

They are about 10". What is confusing is the problem started to appear before I starting any nutes. I have only fed then once since and they sure semed to love it. The only things I can think of soil too hot (thought I saw issues with soil earlier), transplanting, starting CalMag. Light was at 22" but raised it to 24". But a light burns plants at top first? The other plants look just fine.

I think you're right when you say that the soil's too hot. It'd explain why the plants are so green with just one feed. Me personally I'd just give water for a bit until they got a little less green but I think they'll be fine.
