Leafs tips curl and shiny dark green leaves

Too much Nitro which is causing dark green shining and clawing (nitrogen toxicity ) of the leaves .Next feed just PH-ed water should make it better.

Thanks guys!!

The shiny dark green and tips pointed downward are signs of nitrogen toxicity. "the claw / talon" Just hold off on feed and give them water. will resolve.

All healthy leaves wil be solid green and have like mini wax lair for protection, which could be misunderstood with overfeed shine. Daylight is the answer, under such lightning I would not do conclusion yet If you think you overfed, just slow down for 2-3 full wet/dry cycles. Good pH and you should be diamond. All the Best !!!

Max feed in coco is about 800 to 900 ppm, so your over that now and ph needs to be 5.8 for veg and 6.2 to 6.3 for flower

With coco, you need to be ph'ing the water in veg at 5.8. You need an ppm ec reader to read your nutrient amounts. If you don't have them don't mix what the label says, go half. Get your self pool test stops so you can adjust your ph properly. If you look at my M.O.A.B. diary it is also soiless. If you read from the start it will teach you everything you need to know about growing soiless. Only difference will be, you need to add a little bit of cal/mg a couple times a week. Would have to do more frequent feedings than I do as well.

dark green and claw shape is a symptom of excess nitrogen

Also 6.5 ph and 1.1 ec

Photos on 18_6 house and garden a and b and cal mag 2 weeks into veg. 28c temp

Are these autos or photos and what stage are you at, how old are they and what ph and ec have you been giving them?

I have been doing 1m per ltr a and b and 1ml per ltr cal mag im in coco what shall I cut down. Thanks
