Thanks for Tha link coloradohigh!!!! Any idea What's causing this? Or How to fix it

No problem Bigwood863, you're most welcome! You haven't splashed any nutrient solution on the leaves have you? Some, not all, of the damage looks likes burns from water/nutrients on leaves under lights on.

No I'm careful to only water under Tha bottom leaves, I mist Tha plant daily but use plain ph'ed tap water that sits for a day or two first. It's only on some of Tha mid to lower leaves.

There is no real need to mist your plants once they have gone past the seedling stage. Misting once in a while to clean the plant up is fine but regular misting can lead to leaf damage especially under HID lighting. I would also look on the underside of the leaves to see if there is any evidence of pests.

OK good to know. I have some some clones that are about 6 weeks old that are Goin into flower in 2 weeks so I'll definitely stop misting them and hopefully that will help. If there is pests is neem oil a good solution for them or is it not good for the buds?

I would suggest you check out - Cannabis Plant and Pest Problem Solver - Pictorial - it can help you to identify and resolve/dispose of the problem and/or pest(s).

No problem! You are most welcome!!

your leaf damage is irregular and appears to be caused by your misting of the plant. Water droplets can magnify the light and burn the leaves of your plants.
