What’s happening to my leaves

[Austinpalm36]

They aren’t yellow. It’s just at some spots on my plants leaves are turning color. I’m color blind so what color that is idk.

cant tell if my Light is to far or to close. or if it’s because of under or overwatering

3 gallon pots watering 2-3 times a week.
water ph : 5.8
Soil ph : 6.8
1500 w led (339actual watts) about 12- 14 inches above canopy, I did the hand test it wasn’t close to hit on my hand at canopy height.

I also gave them their first feeding yesterday. 2 teaspoons of fox farms big bloom. 1/4 teaspoon of foxfarms grow big. And 1 teaspoon of cal mag. Yesterday was 3 weeks. So I fed 1/4 recommended by the chart. Or until I reached about 400-500ppm. Sorry forgot to put this in the post.

Get a magnifier and make sure you dont have any microscopic critters.
But nice plants you got there.
