It looks like bleaching from too much light coupled with stress from said bleaching causing the deformed tips.

Total guess though, I would seek more expert opinions.

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?!?!?!

overwatering
also seedlings do not need any nutes until the two small round cotyledons leaves are dying. the seed comes with everything it needs until than.

looks like your pretty much there, just start with a tiny bit, as giving to strong a dose is worse than a light dose.

Overwatering, and overfeeding to come. You generally don't want to use time release ferts with pot. You want to be able to change the level of nitrogen, in particular, over the plant's life. Also, since you are clearly new, you need to understand that fertilizer is NOT FOOD. It's more like vitamins. Light is food. If you supply more ferts than the plant can use due to available light, they will be toxic. Also, know that overwatering looks like a deficiency. This is because overwatering kills the root ends, and the plant struggles to obtain nutes and water from the soil. Pot roots in particular like being on the edge of dry.

u guys- i don't have soil-
did u mention wood chips
over moisture n possibly mould potential? just so i know- what's the intel behind wood chips?

well i’m not sure if it’s totally bad, but who knows where they come from, they can get in the way of growing roots . etc,
i just don’t like the idea of them mixed in, i usually break up my nutrimix hp by hand and pick out the chips.

Wood chips mixed with N make compost. Woodchips in the garden can deplete the N. Saw that on a compost 101 article.

Adding time release nutes is a tricky topic. I add them every grow, but my regular feeding are spaced about 2 weeks apart. This allows the regular feeding nutes to get used up and avoid excess salts and stuff, but I don't use much of the timed release stuff... just enough to get the plants thru to the next major feeding. It is very easy to over-feed plants by doing this, and some strains are a lot more sensitive to excess nutes than others. Time release nutes generally work by osmotic action... the water in the soil leaches out the fertilizer. Having a lot of water in your soil/medium can cause them to release more nutes than normal, complicating the feeding. Overwatering seems to be the reason for the pale and puffy appearance of the leaves, but the beginnings of overfeeding can be seen by the start of twisting leaves.
As was mentioned earlier, plants don't need much nutrients until they really start to grow, and most folks think that you can't grow a good crop without dumping a ton of potions and powders on them. Some folks are able to pull it off, but I prefer using a lot less nutes than the makers recommend... they are in it for the cash. Using 2-3X what is needed results in 2-3X more $$$. Look around at the healthy weeds and stuff all around you... who is feeding them constantly? A little help is great, nute wise, but stuffing more nutes into the soil doesn't make things any better for the plant beyond a certain level.
