plants yellow, brown and curling help

i was wondering what is going on i thoght it was nute burn but ive have flush them but i dont know how much water to use. i might not of used enough.

start ph-ing ur water
since u have flushed,apply 1/4-1/2 nutes at 5.5-6 ph

my plants leaves started twisting when my soil's PH was WAY to low. since ur using rock wool check the waters PH

i have checked the run off and it said 5.8-6.0 that should be fine.i flushed the first four pics but havent added any nutes again. the temps are on point and they are two weeks old if that helps thanks

And what was the ph of the water that was put in before runoff???

it was 5.7-5.8

yolu may use right ph and i use lower than that for wool...5.5, but if you keep them to wet it will kill the roots o2 and this can also effrect in htis way like a ph. it does look like ph with the twisty leaves and burnt edges. that twisty is usualy a k issues caused by pH

so i should use 5.5 next time to get it down a little on the run off. and should i flush them again to get the run of down or use nutes i put in 350 ppm nutes thanks alot for the help

these are all rooted right???. id use 5.5 always in wools. 350 seems ok for age if well rooted.

how often you watering or feeding these. and what light you using...

im using 2 t5s and watering every couple days the first watering i did over water them. well most of them have roots starting out the bottom about 1/4 inch. are they ready for veg or should i wait

wait for veg?..how?. your vegging now if they are alive.
id just drop pH to 5.5 and keep doing what your doing. see how they do over next couple days

i mean move them under the mh with co2 how long do the roots out the bottom be before i put them in my hydro dwc

why wait. you`ve gone to the bigger cubes i see so get em in there. ???. roots arent going to show out till tis healthy and growing again. be patient. lots of us try and rush them and it just does the opposite for us

and your hyfro..so feed feed feed..dont water. they need food always as its a hydro and no medium to hold foods. man just woke up here...lol may make sence to why its deff but ph and food is fine.

thanks alot main u have been a big help first hydro grow. will the smaller ones catch up

dood. i appologize for sounding like an ass..i was. but anyone i see dive in this deep right off the bat fall on their face.
with co2 and so on you need a real set up to get what they claim it does from it. and for never growi8ng before it just dont make sence to try yet. keep basic and learn a few grows then move up. youll be bale to set up and use it alot easier and then be happy in the end. or youll just keep being frustrated as why things arent working like a book said so. take the books with a grain of salt. most arent even growers and have no more exp than you do at it. they are publishers not growers and are owned by money and selling their books..not all are crap

its all good man ive grown outside but never did hydro or rw so just a little worried. as for the co2 i know its jumping into it ive put in alot of time reading and running test on everything i can think of to see if i can do before i even started it was like a month before i planted.i can understand about the co2 thing and alot of my friends have not done good with it, but they didnt take care of it and just didnt care. this is what i do and am in college trying to take hort. somewere. now i dont mean to sound like a dick i do thank u for all ur help

ok well it takes alot of money to make co2 work as they say to gain the up to 30% more. need to have a completely sealed air tight room. and vent the room by scrubbing not filtering it or you will just pump all the co2 out and be a waste. in my last home i had 10k invested in it for equipment and so on. co2 didnt even do as it claimed for me in there and was a sealed set up. it helped bu i never once got 30% more. there are alot more important thinbgs to spend on before co2.
kinda a weird comparison here but may make it easier....look at it like building a car. get the thing running and tuned up first and painted nice. then once its all good as a reg daily driver then we can customize it with superchargers...get the basics down first. ive also done schooling and the real world isnt always as they say in the books or classes. youll see that practical exp is the best for anything we want to do in life rather than classes or books. they help but dont think that is the only way to skin da cat....lol
