My poor babies that are in keg cups are so unhealthy. Please help. I noticed a couple days ago that my girls where looking lime green, wilted some even with clawed leaves. I recently did some transplanting and noticed the problem after the tp. Or better yet I noticed after changing to a bigger light. Yah after changing to a larger light we've been struggling. I ph my nutes at 5.8. PPM is usually around 800 to 1000 for the plants in keg cups.
flush with pure ro water. Maybe a 1/2 gallon or more. No nutes. Use a weaker light for now. Wait 2 or 3 days without watering.
also make sure you have plenty of holes in the bottom for good drainage. Are you sure your using coco?
It looks like some type of nutrient lockout to me, probably due to a salt build-up. I agree, you should give them a good flush. A ppm of 800-1000 is pretty high for a plant that young. I'm usually feeding mine in the 400-500 range at that size. Is that coco?
