super young plant prob

so yes im using 4 t5 ho 3 ft . and only 1 fan so ther i no real air outake or anything just a crack in the bottom of the door the humidyty is always about 60 to 80 prcnt and temp beetween 23 and 29 and i have this young plant its my biggest one by the way and its starting to get the tip of the leaves brown and all the litle point on sides of leaves are getting yellow it was like 2 inches from de fluorescent so i brought it too 5 inch and it seem to be worst ive never fed her and i use cheap potting soil from wallmart that as perlite and other stuff in it so if i dont water really much but the soil seems moist at least 3 inch deep here are the pics do you think its hungry or thirsty or maybe lack of fresh air ??
sorry about the quality i dont even have a camera so i used te cam on my compute so i cant even see what im shooting but you clearly see that the tip is brown and sides are getting yellow what te fuck is thatt shit !!!!!!!!!!!!

too much nuts in soil it will be fine just give it 6.4-6.8pH water

ok so the
soil we buy can have too much nute aleready ?? and its real cheap soil so it make sense so i shouldnt give it anything just let her do the work ??

its also funny that dont have any idea of the strain of thar baby cause i bought a indoor mix in a headshop here in QC and it was the only thing they had it cost 30 bucks for 10 seeds its real cheap and only one ever got out of the soil lol and its tat little motherfucker you see here

know it is turning very very ligth green are they burning or what ?

it gets to almost 29 degrees during the day maybe theyr too hot ??

Nah, I think that the above posters are right, more than likely a nute prob, just keep on a ph'd water regimen until more new growth appears, at that stage, the nutrients in the soil will keep the plant going for some time. Wouldnt hurt to check the ph of your soil either, I've heard of cases where 1 low ph watering can cause this sort of thing as well.

also what is your soil makeup? May not be enough "n" in the mix, personally I've went down that road and its a pain to get the plant back on track, BUT it can be done with some extra tlc and attention. If its the soil I would look for an organic solution before turning to chem nutes to amend your soil. I have used coffee grounds that have be used in your coffee, then dried, and sprinkled lightly on the top layer of soil before watering, this acts as a slow release Nitrogen and in my experience you dont need a whole lot, besides using too much will send your soil acidity wonky. just my thought on the topic

thanks a lot darknesslives ill check my ph for sure ... and like that coffe idea since im into natural stuff ... now its a couple week later and the plant is looking realleay nice just some kind of ligther stains on the leaves a little bit like if somebody dropped bleach on it can you figure out what i mean ?? here a pic of the motherfucker
