looks pretty clearly over-watered to me
I've been checking the ph all day and trying to keep it just below 6 I'm looking at the drop test with incandescent light cause they said hid messes it up and flouros seem to make it look goofy too...I have a 5 gallon tank sitting out ready to be switched in with 1/4 teaspoon of food so that should keep the ppm down way below 300 I know the ph of the 5 gallon waiting to go in is just below 6 so I'm hoping my fluctuating ph is taken care of now...would it make sense that ph would climb really fast for a bit after over nuting? I'm hoping that's the case cause it should level out once the plants stop pushing out the extra we'll see I'm keeping my fingers crossed that this next flush resolves the issues atleast the severity anyway thanks so much weedhound for all the help so far I'll keep this thread posted...
running at 1/4 teaspoon for the 5 gallons at just under 6 ph maybe right at 6 the res is at like 73 right now and the air by the plants is about 75
Good! Hopefully you will see a change soon. The really crispy parts of your leaves will die off so don't be surprised but you should the rest of them begin to perk up within a day or so if you are on th ph thing.
The drop test deal is fine.....if you hold the tested water against a white background it helps...(I have fish :) ) If you can stay between 5.5-6.5 you are good. Keep your nutes on the very low to none side for awhile.
Some ph issues simply are caused by the water you use...some tap water is extremely hard to keep ph stabilized which is why many people use RO or distilled. Fixing your ph several times a day can get old REALLY QUICK and those types of water stay more stable in my opinion. There are also cool setups you can buy that do nothing but keep your ph adjusted. Just some other cud to chew on ....:D
Somewhere on these forums (I think in the indoor growing section somewhere) I started a thread on my trying out molassas in my grow and the resulting ph horrors that I caused in my plants and had to fix. If you have time to read it you may find it interesting. So yes....overnuting, among other things, can cause quick rises in ph.
I put it in at just under 6 last night and checked before I went to bed I added just a touch of down to put it closer to 5.2 - 5.5 for the night and when I got up it was decent at around 6.5 so hopefully it will even out quicker than before the plants already look a ton better but like you said (weedhound) the really brittle leaves are doubtfully gonna recover...on the bright side none of the leaves are hanging straight at the side they are all atleast trying to fan out so in the 2 days time they've seemed to show life again I just took a pic I'll post it below *keeping my fingers crossed* tonight I'll get a pic that isn't distorted from the hid
Yes they do look better! Keep it up!:thumbsup: I will check back tonight.:)
That's what I thought, but the wilted appearance seems to say 'overwatered'. But working out some of these other issues should help.Quote:

The only brown you mentioned was spots... That says either pH shock (highly likely considering the info below) or hot spots from the foil around your light (also likely).Quote:

75 is high for rez, but great for room temp. Move your space heater further from the rez maybe?Quote:

Yikes. Okay - pH shock does all kinds of bad things to your plant, to say nothing of the nutrient problems it causes. Some nutrients are being locked out at your lower and higher pHs, so you get deprivation, but other nutes are not locked out, so you get overnute of those. Gotta get that pH under control before anything else.Quote:

the nute issue seems to be better left super low currently at 1/4 teaspoon for the 5 gallon res From now on I'm definately going to let the water sit out for atleast a day as this does seem to help the ph stabilize a bit I've been checking the ph for the last couple days and the roller coaster seems to be running out of steam as the ups and downs are limited to about 1 full point rather than 4
The dehumidifier was the only meter I had so I just put it in there to check it...it's not running in that area cause like you said being tropical during veg stage I'd rather have em be moist as possible
I'm thinking about getting an interval timer for the pump and a heat rod as well so the space heater can be removed from the loop not only is it expensive but it's not easy to estimate heat by guessing how far to move it from the res I want it as self sustaining as I can get
you mentioned wrinkly leaves as a sign and I do notice that the new leaves definately appear quite wrinkled I'm not sure if new growth starts out wrinkled and then gets flatter and smoother as the leaf itself matures so I'm going to keep an eye on this...I'm sure at night I could leave the pump off for much longer than it could be during the day but I've heard that you aren't supposed to turn the pump off at all so I'll tweak that over the next week or so like you said about the ph I don't want to change a bunch of things drastically and not learn what changes brought about what effect
as long as yer sure the res can be as low as 60 I'm going to make sure the space heater is angled away and started above the res to avoid heating it unnecessarily I'm trying to keep as close an eye on it as possible...all the help has been wonderful they're starting to look like they might pull through *hopes*
when it comes to aero I'm still not sure how fast they should be growing I've heard as much as 2 inches or so on an 18/6 daily cycle but it doesn't say at what height the start was so maybe that's only with older plants and a more established root system I'm really thinking that the over water problem was more apparent before the roots were hanging out through the nets as now they are hangin in misted air the over water issue should subside I'm trying to pay close attention to this so I can better help myself and others that might choose to grow this way in the future
again thanks a million for the help I'll be posting again later tonight with an updated pic and info:thumbsup:
They definitely look better, and it sounds like you're on the right track now. I'll keep checking in!
Honestly, this was a complete ph problem, the wilting was not over water, but underwatering, becuase the plant cant get what it needs at >6. They dried out once they became so dehydrated. The plant doesnt really need to take in nutes at this stage so it has nothing to do with under over fert or lockouts. They have all they need but good plain ph'ed water, No one seemed to realize the fact that there to young to take in nutes yet or were. I cant belive u were having this much trouble with the ph, every res change shoudl ph twice a day for 2 days and then after once a day or when needed. I find my ph levels out a couple days after a res change.
