    loooks like they could use some more light. What is your ventilation like? that can usually cause them to wilt too

    akslipped Member

    akslipped Member

    well i changed my rez with less than normal nutes and then they looked good i closed bedroom door and they went down.. but theyve went down with the door was open.. so wtf is it!!#@[email protected]$+_9 its driving me nuts!!!

    smallclosetgrowr Well-Known Member

    they dont even look that bad i wouldnt stress , althought that yellowing on the bottom leaves is either nitro deffiency or to much nutes , or not enuff light reaching them"which i doubt"

    smallclosetgrowr Well-Known Member

    i would keep the air fresh make sure your airstones aint clogged and theres plenty of air in the water .. try even taking out most of the water so only a little bit of the roots are touch the water.i would make a new batch of nutrient solution also

    akslipped Member

    well now i thought i had it all and again 4.30 am.. and ther down.. way down but i found another problem... humidity!!! its down to 35 percent must go down at this time every day and when i town off my light the humidity goes up there for the plants go up so i need to get a humidifier but for a temperarey sulotion i switched the lighting schedule so the dark time is during the dry time... 35 percent humidity can cause this tho?

    Earlymorninghigh Well-Known Member

    Still too much nutes. If there only 3-4 weeks from seed, water, maybe a ml or two per gallon of water, but that's all they really need. If your humidity is around 40%, that's fine, but you don't need 4 fans blowing on them if the air is that dry. Run plain, PHd balanced water for 2-3 days and lighten up on the fan. Remember, less is more. Droopy leaves can also mean you are over watering, remember, rockwool holds a ton of water. You should check out Uncle Ben's plant moisture stress symptoms, don't have the link handy, but easy to find on this site.

    I have very low humidity in my grow room, never goes above 45% and most of the time it's right around 30%. my plants were germed in this room so maybe that is why i dont have your problem. It might just be you need to flush with straight water for a couple days and see if they perk back up. good luck

    You say you have 6 airstones, what size airstones are they? And what size airpump are you using?

    akslipped Member

    Ive got i think 5 in this tub now. 2 of the 99 cent store 1's and 3 the middle sized i think 6 inches or maybe bigger i don't know. I have more of the smaller 99 cent store ones. I cant figure out which to use. I have 4 walmart dual pumps tho as well for 2 tubs and I'm using 5 of the airstones on the tub with the larger plants so get more because there roots are larger. O yeah the roots are still growing fast. The plants seem to be on a timer every night around 3am is when they droop it seems. I don't get it water level is low... ph is low i ordered a ppm tester and i used 2 diff kinds of strips for now and neither of them changed colors so i don't think its over fert. If it was wouldn't they stay droopy?? instead of perky all day until 3am droop i close the closet then in the mourning there perky again. I change something else Ive done pretty much everything everyone has told me on here. Drowning sounds reasonable i guess, but wouldn't they be drowning all day?? i dont get it the temp it fluctuate a little tonight before they drooped i had to turn on the ac a couple times to keep it down maybe cold air blowing on them made them droop?? its annoying as all hell figuring it out, but at least Ive perfected allot of things since now if i could just get past this!!!! i wish there was like a place in town i could call and have them come look at them lol. I have pictures and everyone says something different. I want to sex them, but I'm scared to traumatize them any could it be to much light from added the cfls maybe and they are were out towards they're dark time so they droop? I've been researching constantly and found several different answers tryed everything and i have gotten the same results its irritating. I appreciate everyone trying to help tho.

    OOOOOooooooo oooo Hydro!!!!!!!!!

    The primary reason I went back to soil :wall:

    Lotsa trying stuff in hydro is bad in water, everything happens fast.

    It looks to me like they are drowning. That rockwool looks soaked and
    thus your roots have no reason to search for a water source

    Have you been top watering and over-filling res. too?

    I really don't think your primary problem is humidity related,
    let the rockwool dry and watch those girls start to act right.

    akslipped Member

    yeah the res level is low they seem to be doing good except for drooping at night or if i turn the ac on and cold air hits them they droop thats the other reason they droop i figured out leaves are pretty dark maybe a small phos deficiency, but ima change the water again soon hopefully ill have my cheapo ppm and ph meter by then and ima get a actual teaspoon because ive been using the cap guessing on nutes thats probably bad to.

    I notice none of the pics show any of the root area (E.C, pH and nutrient temperature are all root issues). DWC and other forms of hydroponics are all about the roots more than the leaves. What state are the roots in and what is the E.C of the reservoir. If poss can you post a pic of the roots thanks.

    akslipped Member

    roots are awsome.. getting bigger than the plants themselves ill get some pics of the roots up tomorrow
