I have been having this issue with this plant for a while I have tried a couple compost teas and topped dressed with some 5-4-2 bio live also cut back the cover crop a bit. It is under a 4 bulb t5 fixture and a blumat dripper with decloronated water. She seems to be growing still… the new growth looks good but after a couple days or so they start to yellow a bit.
Welcome to the forum.
I had the same look to my leaves and it turned out to be a mag deficiency. Try 1 tsp/gallon of epsom salt added to your next feeding. I would start there. The other deficiency could be N.
Looks like you are catching it early. Shouldn’t be an issue.
Thank you for help I have watered in some Epsom salt and also used some for a foliar spray hope it works … thank u again for the help
No worries. Let us know if you need anything else. When I use General Hydropoinics, I put 1/4 tsp Epsom’s per gallon unless I see a deficiency in which case I increase up to the 1 tsp Bubblehead mentioned.
