What's wrong here?

Hey guys. First grow in a long time...not sure what's causing this....leaves are turning yellow at the tips and edges and spreading over the leaf. It's happening to all of then at various stages. Using sensitive grow a and b with Ph perfect. 300 Watt full spectrum led. I have two now but when it started I only had one. Idk How well the pics turned out.

Impossible to tell with your LED on, take some pictures under natural lighting for a better analysis and recommendation.

As per A4's request we moved this over to the infirmary, and second his request for better pic's..

Yar, better pics needed If ya shut ur lites off and use flash on ur camera it will get ya a good pic. Are they clones? If so its normal for the leaves to yellow and die on bottom.

Could be bleaching too? Looks like your light is pretty close.

No clones.I haven't gotten they're yet. So I can still hurt the leaves with an Led if it's to close? I thought I was able to get the light closer without harming them. I'll have better pics in a minute tho.

300 watts is alot I light ly bleached my cotton candy tops at 10-12in from canopy with a 300 watt led (actual draw.) All just a shot in the dark lol. When ya get those pics up im sure someone more knowledgeable than me will help

Even with the LEDs on I can tell it's not bleaching. If it were, the veins wouldn't still be green, they would be bleached out as well. Besides the new pictures, also let us know how often you are feeding and at what strength.

The 5 bigger pots I feed sensigrow a and b. About 1/8th of a teaspoon in a gallon of water each. I wait until the soil is about dry on top. Im growing in 3 gallon fabric pots with happy frog soil. The sensi nutes I have are Ph perfect as well. When I test though the water before nutes is steady between 6.5/7.0
