What type of soil is it in? What type feeding has it gotten? When was the last feed and or watering in relation to the start of the problems. Could the brown spots in the last pic be a chemical splash? I think this info might help some of the farmers answer your concerns. Have you changed distance to lights, etc.

Its in full circle organic compost. Last feed was 5 days ago last water was yesterday these are pics from today. The problem started about a week and half ago before switching to new feed. was using some feed from hydro store and talked to other hydro store told me to drop that feed so i changed to sensi grow 2 part feed with ph balancer. My temps are averaging 75 to 83 with lights on and humidity around 40 to 55. Hps 600w and about 15in. Away

You spilled nutes on that plant.

I didn't though ive only fed once and was super careful when i did not to splash

The pic in post five seems to show the burned leaf tips common to fertilizer burn. If you can check the ph or tds, do so. Otherwise I would leach the soil to remove excesses.

Ph is 6.5 i have ph regulator in my nutes in been at 6.5 for over a week even tested my drainage. Im gonna flush today and transplant 2 to coco soiless see if that helps

Foliar spray with calcium... Under the leaves as well as on top of the leaves, then turn the lights out for a few hours till it dries.

What does the calcium do?
