Well I solved problem tried some calmag and a tea no results I was root bound on most of them had to get them to 5 gal fabric pots after few days to week after transplanting to ground swell and using great white they are back to looking green like they should and started growing again exploded with new growth thanks for the help everyone
Are you able to get a runoff pH and PPM measurement? Also do you have a fan blowing air towards that part of the plant? It kind of looks like wind burn.
Hi, it kind of looks like nutrient burn. The tips of the leaves throughout the plant look burnt but the rest of the leaf looks ok.
I'm just guessing and curious to see what others think.
