Top leaves dried out, not a light burn though

So I have a 1000w hps light about 2 1/2 - 3 ft above the babies I got which have been growing for 5 weeks exactly today. They were thriving until this morning I woke up an checked on em, it looks like a light burn but how can it be if the light is so high? The temperature is about 74 f and 50% humidity so idk what the problem is......also I have another guy with one of his leaves curling, I'm assuming it's a ph problem, but I added a photo anyway for more insight, hope this turns around as I have jus started and paid good money for these seeds.

do you have a fan on in there. Just think of it like this. we can get a sun burn when it not to hot for us and so can a plant. good air flow is the key.you might try to move or turn them once a day.

Whats your feed schedule and medium? Did you just feed them? Airflow and strain, there's a lot that can be compiled with this info but with just a pic it's nothing but a guess. If you put more info it just means your answers can be more accurate.
 
My medium is made up of 60% fox farm ocean forest and 40% light warrior mixed, and no I haven't fed them yet, the soil should be enough nutes for the first month and a half since it's such a hot medium. The only additive I put in was neem oil for any future pests and fungus and a couple drops of ocean minerals in the water when I first watered them, the ph is 6.0- 6.5 and there's good air flow, I have a oscillating fan with 2 vents that suck air in and out through a filter. So idk what's going on...I took another picture this morning, it's getting worse...

welcome to RIU! i'm sure there will be an experienced grower around soon to help you. maybe for now you should just try to raise your lights a bit? also, a more focused picture closer to the plant will probably be asked for-what's up now makes it hard to focus on the problem areas. sorry i've got nothing for ya' but this post will at least 'bump' this too, so good luck!
