PLEASE HELP!!! My plants are sick

[Lemonsdopegrow]

I have 6 soil plants and 5 coco coir that have been amended with 2 scoops per gallon of 4-4-4 all purpose time release and I water the soil plants around 6.5 and the coco coir at 6.0 the temp ranges at 75 to 80 in the room I water the coco coir every day to every other day slightly just to make the top soil moist. With the soil I water every every 2 days usually but I tend to spread it out more but the issue is on both soil and coco coir plants and seems to be spreading fast. At first I thought it was mobile meaning it started from the bottom but now I’m not sure. Some of it looks like blotches that start in the mid leaf but most starts at the tips. With the coco coir I had a recent ph issue causing a iron deficiency and It has been fixed but I’ve done extensive research and I’m just not 100 percent sure what I’m dealing with can anyone help please?!?!?!

Hey. Can you show close up under the leaf? What lights and how high?

It’s a Mars 300 and it’s around a foot and a half to 2 feet away

I am not an expert, but I see bleaching so my guess is that light is too close for its comfort. I would put it at 36 inches or more until the plant recovers and has a growth spurt.
