It's only 73 outside the box, in the rest of the apartment, so its not the outside temp. I Superthrived them when I watered last night, and they're looking a lot better, although they still look rough. Should I trim off the dead/nearly dead leaves, or just leave them on? Smokedoja, how big are your intake holes at the bottom of your grow box? Thanks All!

personally i would leave them on until they come off with a gentle tug if that, but some may disagree, and my intake hole is 2 inches

hey here's a big warning for you, these plants get DENSE FAST, but only near the end. If you want to flower them for the full 11-12 weeks you'll need some type of mold prevention if your ambient humidity level is over 40%

Hey all. Got some new pics. They're starting to come around again. I didn't have a chance to add that plexiglass like I was hoping.... maybe it will happen this weekend. I think my biggest problem is that although my fan theoretically can change the air in the box every few seconds, the boxes are too big (30 gallons) for it to pull the air effectively from the other side of the box. Smokedoja, how big were your containers? I guess its ok, though, since I was hoping to build another smaller one for moms and clones, so I could use that fan for that one. If it happens. Anyways, one of the babies is getting yellow spotted leaves again, even with less watering (third pic). I was wondering if a little H2O2 (Hydrogen Peroxide) could be mixed with my water to deliver more oxygen to the roots. Does anyone know if that would work/has anyone tried that before? Thanks All!

NOOO H202 is like alcohol, it kills the good and bad, along with delivering oxygen to roots, but it's not worth it. You need the beneficial microbes in the soil to turn organic and inorganic compounds into usable plant foods. along with(sometimes) getting rid of plant wastes in the root system.

I had the same problem on a few of my Jh, I could never figure out what was causing it. just be careful not to overfeed your plant trying to correct it. I did and it burned FAST.

here's what you have to look forward to. after 10 weeks flower.

The fan is 63 cfm, inside a 7.something cf space. So it should be changing the air every 8 seconds or so. But I think its not powerful enough pull air in, because to do so it would have to move most of the other air in the box. Thanks, Kieahtoka, for the warning. I guess I'll just keep on keeping on. Thanks all.

my boxes are each 35 gallons.... do you think that the heat is causing the yellow spots?

thenoffya · #30 (**permalink**) 10-31-2007, 05:26 PM

With the second fan I have at the bottom, it's maxed out at 82F lately, so I don't think that it is the heat. Man, I can't wait til I have something that looks like Kieahtoka's pics. Thanks All

smokedoja · #31 (**permalink**) 10-31-2007, 05:30 PM

hell yea dude keep up the good work and you will

OK, I think I may have figured out what is partly to blame for the yellowing leaves. I was looking at the watering device that I use for my plants, and I realized that I have been giving them half a cup of water, not a quarter like I though. So instead of them thinking it rained every other day, it flooded every four or five. I bet thats why they aren't doing so hot. I posted a pic of my new watering device, with accurate ounce measurements. You can see on the sticker right underneath the triangle the line where I thought a quarter cup (2 ounces) was, right on the four ounce line. Hopefully, thats the end of the yellowing.

P.S. They look almost the same as yesterday

Kieahtoka · #33 (**permalink**) 11-01-2007, 03:58 AM

honestly my friend.. it doesn't matter between a half and a quarter cup, the plants don't notice a difference, I DRENCH my pots every 2 days, giving about the same amount of water as there is soil. No matter how much water you give the soil will hold as much as it can either way, but if you give too much(3 times your soil volume) you can leach nutrients out. That is not the same as over watering looks.

I think it might be iron def, here's a pic, tell me if it looks similar.

that's not mine, I copied it from google, but that is definitely iron defficiency.

No, its the old leaves on mine that are turning yellow, not the newer ones. And theres black spots, too.

blakeb · #37 (**permalink**) 11-01-2007, 01:39 PM

blavk spots? what causes that?

#38 (**permalink**) 11-01-2007, 04:39 PM

Black spot? that means you could have some bug problem. If its on your bottom leaves it could be thrips if its on your top leaves it could be mites.

ClosetDWC · #39 (**permalink**) 11-01-2007, 04:51 PM

Thrips make shiny spots on the leaf where they extract the chlorophyll from and it will eventually turn brown then black. if they are at the very bottow and dont look to be productive you may want to remove them .but that is imo

mabee i should have made this clearer you can add h2o2 but only in small doeses like 1% in your water...an only if you use the highgrade stuff not the store bought kind..i forget the percentages but the lower ones are cut different...also useing h2o2 to kill bactiera between grows is great..u.s farmers use h2o2 solutions from everything from killin bacteria to supplementing it with the nutes...i have an artice about it in one of my can.culture mags...if you need i can give you the issuse number so you can refrence it off the site..peace
