I don't know how close your lights are from the top of the plant? She looks starved for moisture and just plain Ph water no nutes she looks like she doesnt like the food and just needs water then grow big. She may not like that combo of food. Just water her to run off let her sit and see if she changes leaf color. Make sure lights are not to close. How old is it? Don't keep tent above 80f don't let fans blow directly on young plants. Good luck

Stop feeding them nutrients. They are way to small. Don't give them anything but PHd water for the first 3-4 weeks.
