help me please

i bought some skunk no.1 clones from a dipensory here in colorado. they were aero clones and i use a 45 gallon bubbler with 30 gallons in it. there about two and a half days old they had about 7 inch roots when i bout them really heathy root systems didnt look like clone the roots were so well developed. i dont know why but i added nutrients last night and the leave ends curled and the tips turned brown. i changed the water to regular ph water right away and it doesent seem to be getting worse. i'm using a 400 watt hps soon to be 1000 and just want to be shure i just over did it on the nutrients ph and everything is ok the light was 3 feet away when it happend so dont think it was that using floro grow nutrients only used half recommended dose so any advice would be helpful in that department its my first grow so any other advice would be helpful the roots were growing by the way checked them today and the roots have been growing well so i dont think there in total shock but any advice would be helpful thanks guyskiss-asssorry the pics suck

nice acting quickly man. my most nervous part is that morning i wake up after i added nutes.. with those leaves turning brown that quickly it probably would of killed them. They should recover fine.. wait til the plant is 4-5 inches tall or 2 weeks, which ever comes first and then add 1/4 strength. next week 1/2. then 2/3. then full after they are 10 inch.. some people give it full strength when they are 5 inches tall but i play it a little bit more conseritively than most

yeah, you should be cool.
good job acting quickly.
you most definitely saved your girls!

thanks for the reply i'll try that. i shouldn't have added nutrients so early on but the roots on these clones were so good i thought they would be ok. do you know how long it will take them to bounce back these pics were taken tonight and i changed the water out last night?

yah a week or longer before they get back on the headie growth spurts, but this isn't taking a week away from it just adding a week to it.

cool thanks man

Absolutely no nutrients till they are at least a couple of feet high otherwise you'll burn the roots and f**k the lot of em. How to fix; flush with water and allow to drain. Keep the humidity around 60 if you can this is the most important thing for clones otherwise they grow skinny and lanking as f**k, remember its a weed which strives off a damp environment. Don't water everyday, while they are young like this give them around 2-3 days in between water and soak on the watering days. Have your lighting around 2-3 feet above, doesn't need to be any special lighting at this stage, maybe fluro now then HPS once they are over a foot high. Easy really. Cheers and best of luck.
