I'd add some cal mag to the mix. As it looks like magnesium to me but I definitely could be wrong. Check out the link below to help trouble shoot https://www.ilovegrowingmarijuana.com/nutrient-deficiencies-in-marijuana-plants/

What’s with this Odd growth rate and leaf pattern Stunted growth on 16 day old northern lights auto. 1/3 coco 2/3 fox farms ocean floor. gave it a minor dose of cal mag plus just in case this is a developing deficiency. It has three nodes but it is very small at approximately 1.5-2 inches. The pattern may be genetic?

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.

Yellow Leaves Autoflower Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)
