Saggy Leaves

[dejayou30]

One of my plants is starting to look sick. The leaves are looking saggy, leaf stems feel limp and noodley, and some of the lower leaves are starting to yellow around the edges. It looks similar to the way the one I killed last grow by over-nuting looked when it first started to die, but then I was running like 1800 PPM and now I am only at around 850-950 so I don't think it could possibly be over nuting.

My pH is normal 5.6-6.1, temp is 69°, PPM is 850-950 and the roots look healthy. I am feeding 100 mL of PBP Bloom, 50 mL CalMag+, 100 mL LK, 75 mL of Sweet Berry, and 75 mL Hygrozyme. I am running an E&F system and I just flushed for a whole day 5 days ago and then changed my res to 900 PPM the next day.

Its night time in the room right now, but I will get a pic when the lights come on in 2 hours. Until then, any suggestions as to what the problem might be?

Hey Deja....
watch your ppms.....are they dropping daily? If so up your nutes. I had that happen in my grows with the CalMag/ProBloom....turned out I was too LOW in nutes and the plants got what i THINK is a copper def....the newer growth wilted. Is it like that? I bet its same damn thing.

I found I got the problem in later flowering if I let my nutes go UNDER 1000. See the buggers were EATING the nutes down and when the number got to low they''d look wilted. (they were eating a couple hundred a day down.

Yeah, changing out the bins I my biggest concern. It is a bitch right now to take the lids with the plants and put them somewhere while I clean the bins. I would have to incorporate some kind of drain with a plug to make that work.

As far as the oxygen, the bins aren't even close to airtight and I don't think an airstone would stay submerged in there. I do have an airstone in the res itself and I use H2O2 every other day so oxygen shouldnt be a problem. My roots did the same thing last time where they grow to a certain point and then stop growing so I didn't think it was that big of a deal but that just shows what I know.

Actually I remember you mentioning it several times and I didn't think too much about it (or your PONTIFICATION about the plants in the corners) so that shows what I know. I was very convinced it was your nutes somehow but couldn't figure out how.

Are you using a zyme product at this point? Something that the roots are sitting seems to be burning or rotting them.....and I'm honestly not sure why.

I'd just stick an airpump line down into your containers....not necessarily in your water. I have a feeling there is less 02 flow in there than should be. It's fine that there is H202 in the solution but the roots still need to breathe even when no solution is present.....extra air pumped in would help I think but it's just a guess. (Ps...H202 level is not too strong is it?????)

Rhizome!! Always good to see you. Would temps that low destroy those roots like that? I've just never seen such a thing.....

You know I love both Jorge's book and Greg Greens book but I honestly don't use either one of those as a hydro guide. I have a feeling both were written slightly before hydro took off so madly but I'm not positive. I AM sure that I don't use their hydro information as a rule. Most of it is too vague anyway. BUT I do find both those books VERY useful in general so I refer to them constantly for other information.

Heh- then Jorge f*cked up. Or the editors/proofreaders.

Way too cold.

Shoot for 70F.

Only things that I know of that get best growth rate/ feed conversion @ 50F are trout and toothfish.

OK, thanks rhizome. I guess I paid $25 for some false information. I wonder how much more bad advice I have read out of there then... I have the heater in there still, just not plugged in. Its actually being used as an anchor for my "bubble curtain" that won't suction to the bottom of my res. :thumbsup: Need to pick up a new stone tomorrow.

Have you looked at any of the pictures I have posted? If so, any idea what my problem is? Or is it just cold temperature related?

What was EC prior to maintenance?

[dejayou30]

Around 1100. I think the highest it read one day was 1140. Oh, and I forgot, today is the 27th day of flower.

What's the media?
