hydro problems - clones are drooping yellowing curling, all of sudden! HELP!

[dubstepa]

hey guys im a first time hydro guy with a diy system.

4x4 grow tent.
great ventilation
6 inch fan 8 inch filter inside vortex fan
70-77F throughout the day inside the tent
first week veg t5 lighting
20 gal res
ph/temp/ppm
6.0-6.3/65-74f/330
i have a 300gpm pump with and air pump hooked up to it blowing air into the water pump before the out take.

i gave 9 bucks draining down into the res each bucket has a 3 inch net pot with a clone from the club coverd in hydroton.

using a drip system that origianly ran for 3 hours/ off for an hour.
roots organics complete nute system.

so guys i ran my system for 5 dayz and it was awsome. i hadnt recieved my meter yet so i was basing ml/gal on 25% strength according to the feeding schedule. about ml/gal of all roots veg products including all the extras and i added a little bit of b1 because i tore off most off the rockwool before i stuck it in my net pots. also added a bit of prop o gator for root take off. remind u less then a ml/gal of each extra addative.

i noticed a bit of burning so i diluted my res with 5 gal of filterd water, saw yellowing and curling thought maybie i lacked magnesium. bought some organic soluble mag AND NOW a couple of my clones are even bending over.

i have 9 strains and there all reacting diff, the purple kush leaves are curling and dying. the mass super skunk is turning yellow and burning and i woke up today and two of them "cheese and urkle romulan are bending over and drooping.
the funny thing is 4 of my clones are thriving showing great root growth and perky like a college freshman coed at a water balloon fight.

im guna empty my res and flush them right now hopefully i get some help from you guys before im done.

no pics sorry use ur imagination i tried to be descriptive. thanx

do you have root development on all clones? if so what does it look like? all white or brown? also how much root mass do you have? are we talking a just a few tap roots or a full blowen system?

what lights are the plants under now? you should keep them under the T5 untill everything is growing, not just roots.

you need to give clones a lot of attention. sometimes it can be a mistake to take small clones to the full setup to early. personal i use a bubble cloner to get my clones from rock wool to the system. if i put them in when i see the first root break the bottom of the rockwool, then in about a week i have well developed roots that are about 2 feet long. i use pure water or about 100-150 ppm of bloom and micro formula. the clones dont need a lot of nutrients to survive. you could grow them fine for a month on pure water without running into problems.

if your plants are buring, flush with water. mix up a solution that is 1/8 strength. i doubt this will change things much but its better to be safe then sorry with med-clones. sometimes directions on nutruent solutions will make a ppm around 1500-2000, so at a quater strenght it could be too much for your plants.

you should also post some pics its very hard to diagnose without visuals.

best of luck. i hope the problems vanish in a cloud of smoke!

also, after re-reading your post, what strains are prospering?

the shiva skunk romulan and a sd mix have been fine through everything. no burns no curling just doin great.

i flushd and have a nice filter, because the bottom of the buckets have a certian level of the water from the batch in them the ppm went up to 240 after a half hour of flushing, i also took a cup and hand flushd each net pot thoroughly. i changed my watering time to 30 minutes every 3 hours, before i was watering for 3 hours and stoping for one hour after watching my friend drip 24/7 and have no problems.
ofcourse i calibrate my meter high low accualy every freakn day so all my ph/temp/ppm are on point.

im going to lay off all nutrients for the day not sure what to do. i worried i should just youthinize the fuckd up clones but what a waste of money, i dnt understand how some could do so well and others give me so many problems.
i took pictures with my mac book, lol
man, i wanna get going already i just strated and already i have problems.
i work in oaksterdam as a vendor and im around enough big crops to know the basics and even above that, but my dumb ass cant do it on his own.

oh and they were all rooted clones, i ripped off most of the rockwool then put it in my system. they perked up right away and were doin really well, i noticed the burn and diluted my solution by a third and today im flushing.
i had the blue chease a couple dayz before the others and i gave it some prop o gator which is a 0-3-2 i added it to a light organics solution according to there formula then added some organic magnesium and i guess i fuckd them up more.
all the plants that are doin ok have roots coming out of the net pots already and the blue cheese had two big roots hanging but there was nutrient all over them making them look brown and sludgy but u could tell the accual roots were white and thriving.

They look severely overwatered to me, like the roots have root-rot. Also, the nutrients should be higher than 330. For their size, it looks like they should be closer to 1000.

i think your right about the over watering but 1000pm would kill my plants man, lol 1000ppm is a mature amount, i must of been around 500-600 when i burned my plants, this is my first attempt at hydro not growing i suggest you dont give out advice, but thanx anyway.
