My plant is having a few issues.

OK there are 4 plants, all have these white/ yellowish tips on the very tip of the leaf. thos leave tips are curling upwards lik a rams horn. they have been on 12/12 for 3 days now and no pistils (i thought i saw some on day two but they are greenish and very long now?) today the closet was linned with tin foil and a 70 watt hps was used to supplement the t5 fluro its under. pro bloom nutes are being used. there is also a fan on constantly with new air coming in, i dont think temp is at all a issue but i dont have a thermometer. water is super oxygenated yet roos are sowing brownish ues where they are thick . is that just a stain from nutes?. there are a few other threads of mine that have this same grow at a younger age.

ps i dont think this condition favors any certain part of the plant

thanks, any advice would be

Cant tell need better pics.. but they look pretty good

my camera kinda sucks so im limited to the pix but in the second picture you can look at the leave on the left side od the pic and you can see what i mean

Looks like that could be Nute burn, maybe Nitrogen.. don't grow hydro though so I don't really know how to help you.

appreciate it i also have done a good amount of trimming ass you can see to get tho shoots shooting out every which way

hey if i were to go by a really nice aquarium filter with a bacteria/metal/mineral/chemical filter and put it in the resivour for a few days would that work to flush/leach my growing medium and plants of all the excess salts and buildup that could be aling them? i have also heard that using some horticultural grade H202 solution could give them a little vigor and correct problems. what about foiliar feeding during flushing? i need some help. gotta lotta ideas but i dont wanna kill anything
