Diagnosis?

See pics. I think it is either light burn or due to watering with the PH too high. It was also a week out from when it was time to top dress when I saw the first symptom.

I've backed the lights off, top dressed, and flushed with properly PH'd water. It seems to be recovering but I'm a noob and don't really know what the issue is.

The plant is about 3 weeks into flower. While we are here, and assuming there will be a harvest, can I get some time left estimates?

Indoors
Watering every day to every other day
Coco Coir
cheap, dry, slow released fertilizer
Growing with cob LED's

The marks on the leaf are from the soil staying wet for too long and ide say a good 6 weeks , you will get a harvest if you can get more air to the roots, fromcthe pic it appears you have used a mix with no perlite for aeration ?

I didn't realize that is where the leaf marks came from. Thanks! I couldn't figure it out.
I was definitely over watering and have corrected it since. I went with no perlite to try it out...oops.

Are you using a Cal mag supplement for your water? It's a must in Coco.

And you don't necessarily need to amend coco. Lots of ppl growing in straight coco.
