What is this?

I would do as Man o Green says and give Epsom salt, but I would not use anymore of the Dr Earth Green Veg bag.
I would use Flower Girl the rest of the way.

It Dr earth's Premium Gold 4-4-4, as per their feeding schedule for cannabis, I had assumed you were using it.
Page 3 of the schedule is what I am roughly using. But since I am using a super soil, I will skip the green bag.

i only used flower girl and the veg

Ok i think my problem is I am burning the shit out of them. Causing lockout. The more I read, the more I think OF should carry a plant out to 6 weeks plus.

If these don’t pull through I will start over and run OF and add nothing but water and see how long it will carry me.

I agree ffof is hot as hell. You can try what I did and mix it in with a less hot soil. Right now im using 3 parts happy frog and 1 part ocean forest. Didnt feed for the first 3 weeks then continued my veg feed like normal. Plants are doing great but they did struggle a bit in the beginning and Im chalking that up to the ocean forest being too hot for seedlings, ocean forest is meant to be transplanted into, with a plant that already has a decent root system.

This was 2 weeks in

And this is now about 40 days in, only feeding 1 time per week, plain water otherwise
