Leaves Curling

Guys all of you wrong, how u dont see that is light stress... Move light higher or less on dimmer

In picture, looks like some leaves have a blueish tint to them? if so that would indicate p-deficiency. Trust your eyes over a picture. Got some light chlorosis along the serated tips around eedges of leaf... this location is typical of problem related to K-deficiency. I'd let them progress a bit further to verify the leaf symptoms. Leaf symptoms are not discrete, but some are more unique than others. If it's progressing slowly that makes it easy to have patience also means the adjustment needs to be smaller too. Better to be certain than compound the current issue with a new one from dumping the wrong stuff on your plant.

Hey pal. So. This will resolve your ISSUE the fastest way.. You need a high dose of mag/sulphur. Best and quickest way to get tnat to your plant is through a foilar spray. Doing the sub will take a few days before it kicks in. You'll see your plant rapidly intake and see improvements within a day So. Get yourself pure Epsom salts (No aloe Vera or lavender). And mix enough salt to add 150ppm to tap. Ph doesn't matter so much. But after you spray dim your lights to very low. Come back 20-30m later and your plants should be pretty dry. Apply until dripping wet and also add it to your sub (make sure you ph match to your sub) Soil 6.5-7 6.7 being optimal Coco 5.5-6 5.5 is optimal for mag/sulphur in coco. I'm nearly sure. But once you keep with those ranges. You'll be good Do soon. Don't spray and preflowers or buds, only during veg or early pre flower. And even then becareful. If you don't have salts. Any pharmacy will have or the female section in the shops. But make sure it's pure. Feel free to dm me if you need any help. Good luck.

What you pointed out along with the plant color being off. I suggest checking the run off waters ph. You probably have a soil ph proble

Magnesium deficiency starts. If its soil, you dont have wet/dry cycle. You water plants while they dont need it yet, that changes ph in pot, thats how you have your troubles with curling and plant colour.
