Canoe-like leaves?

[Socrates]

Hey all, I posted something about this in the indoor soil forum but I guess that was the wrong place for it. Anyway, S.W.I.M. has these plants about 4 weeks into 12/12, and the small leaves close to the stem are sort of drooping. Except they're not really drooping so much as folding down and in on themselves...it doesn't seem to be over or underwatering, and the plants are otherwise healthy. Any ideas?







and the same plant from a bit farther back:

What are temps? Ph of water/runoff etc?

 

[sproutco]

More information will get you a better answer. What is in the soil? What is being fed to the plants? (be specific and include ppm of each element or % in the fertilizer) What is the ph of the fertilizer plus water when mixed? What is the ph of the soil?

N overdose...

Temps are like 78-85 with the lights on, they're in miracle-grow soil (I know, I know) with added perlite and vermiculite, as well as a little bit of bone and blood meal. They are fed every couple of waterings with 10-30-20 in pretty conservative dosages. Only a couple of the plants are like this, the others are fine.

hey,

nextime use organic soil youll see a big change and make sure u flush really good that miracle grow stuff taste pretty nasty

goodl cuk

You need a source of calcium and magnesium if the soil does not contain dolomite lime. I will guess that 10-30-20 is peters bloom booster. It does contain a slight amount of magnesium (.5%). You should use about 1 teaspoon per gallon of water plus 1/8 teaspoon epsom salts plus 1/4 teaspoon powdered gypsum. Add the gypsum/epsom salts if the soil contains no dolomite with every fert. If it does contain dolomite, you might add it every 3 or 4 waterings. Ph of your fert. water after mixing is important. Aim for about 5.8 to 6 At least use ph test strips so you will get an idea of what is going on and not grow blind. If you are not using peter's fert. and your fert contains no magnesium, increase epsom salt from 1/8 teaspoon to 1/4 teaspoon instead.

Peters ferts are correct, that plant that I was talking about just hermed I think, so it may be a moot point. However, there were only like 4 male flowers - unfortunately I only saw them because they'd already opened. I'm hoping they didn't really mess everything up, even though I have a bad feeling that they did. I searched the plant thoroughly and don't see any more flowers. Do you think I should just kill it, or is it possible that it was just a few freaks?

 

[sproutco]

Different plants have different degrees of being hermi it seems. Some plants may produce only a few flowers that you can remove and they don't hermi anymore. I think I would keep them another week or so or until they finish blooming but check them everyday for more flowers forming. I used to have a skunk#1 hermi and you could remove the few male flowers that would form under the main buds and have a seedless crop. I did this for years. I don't recommend keeping hermi's longterm cause they are really a pain in the %^&.

Thanks for the quick replies sprout, you're always very helpful and well-informed. My friend who is also on this board mentioned you by name recently, in fact. I'll leave them in there under flouros separated a bit from the hps area, just to keep an eye on them and see if it's safe to put them back.

Any tips on how to spot male flowers in among all those female buds? The male flowers look awfully similar until they open (at least to my untrained eye).

 

[sproutco]

Been a long time, 15 years, since I did hermi flower removal. I do remember that you have to go over each flower carefully like a surgeon. This was with my plant and they were somewhat easy to spot. Only a few would appear right under the main bud along the stem. I have seen hermi flowers in pictures that were imbedded into the main bud and it seemed like those would be impossible to extract and find. Who knows...your plant may only hermi once and not anymore.

 

[Socrates]

That's where I found the ones so far, but I only found them because they were open. I'm really hoping that's the end of them, because that Jack was smelling and looking great.

Damn, 15 years, no wonder you know so much. Lots of respect man, I'd throw a lot of K+ your way if I could. Thanks again for your help.

Jack Herer has known problems with hermies...your nute/environment issues may have caused the hermie, but most likely it's just the genetics. If you like the smoke keep it...but if you're got a bunch of other known females then it's going to cause hassles most likely that aren't worth it IMO.

If you've got excellent airflow and ventilation, then you can spray the buds with water to make the pollen unviable...but you run the risk of bud rot if you can't dry the buds out after spraying them. Definitely not my first choice, but it works.
