2 crown royal plants and using gh micro nutes in coco , 900 watt mars led about 20 inches from plants , they are 3 weeks in to veg and stopped growing and started showing this different leaf shape and razored edges , ph is 5.8 and nutes are 250ppm
I have a fan and temps never get over 80 in the tent and the light is 24 inches away and my electronic laser temp probe reads 70-71 at the leaf top , I am only using a led light and 900 watts(450 watts from the wall outlet ) in a 4x4x8 tent and it is only on the left side and center of the plant not the right side of plant canopy .does changing nute from organic to gh flora series do this ?if so will they grow out of it ?
could it be nitrogen toxicity or some other nute problem, so just let them do their thing ? would you give water or give them nutes too ?I have been giving nutes daily and ppm about 250
What's your humidity? If it's low, they can't handle as much heat.
Don't stress out too much. Raise that light a little
Maybe hang a damp towel in there if humidty is low. And chill.
Other than some heat stress they're doing just fine.
If you see anything else develop, then it's time to troubleshoot your nutes and ph.
Edit if heat and humidity are fine. It looks like you have a ton of drainage , but how often are you watering? Make sure to let them dry out eniugh. And not overwater
Whatever you’ve been doing with the feeding is working fine. coco is meant to be fed every day.
I don’t see any nutrient problem. You could double check your RH and temps. The little digital thermo/hygrometers that we all use aren’t always reliable. But really- I’d be happy if my plants looked like that.
