Twisted blades?

[Chronic Chrissy]

OK the plant in question is a 3 day old Northern. I grow in sunshine mix 4(soil w/ perlite) and use chemicle nutes, the pH is at about 6.5. I use a 400w MH bulb. The temp is a steady 79-80, and humidity is 28-35%. Today I flushed, transplanted then fed with 1/2 concentrated 10-10-10. Then a few hours later once they had a chance to absorbe the water I LST'ed a little to expose some branchs. Now it is only one blade on one leaf that is twisting. I don't know what it could be from...blushing...it could be any one or a combo of everything I threw at her today. On another one of my Northerns(Exact same for everything above) one of the leaves blades seem to be slightly tilted but no where near twisted. Is it just my plant recentering itself, or WTF????

I wouldn't worry too much, they grow out of it. Sometimes cool night time temps can do it and some strains like BlueBarry are more prone to it in their earlier stages of growth.

Single twisted leaves is nothing to worry about but are you already fertilizing at 3 days? :eek:

LOL! Only 1 leaf? hehehe... I have over a dozen leaves curled in odd shapes, another 2 dozen with tip burns & side burns (CFL light, not nute), and quite a few pointing in weird directions. I figured it's because of the macguyver lighting. The plants look otherwise healthy & lush, so I shrug it off as a "bad hair day". Bad hair styling don't mean shit to the body underneath. And cosmetic leaf damage don't mean shit to plants.

I grabbed the cam and took some example shots of what I mean.

Volker you seem to have a heat or overfert problem. That isn't cosmetic damage.

If the leaves curl up then there trying to keep cool.

The next step is they start fanning themselves [FAN LEAVES... get it...durrr] and then they will ask you for a cold beer.

Volker you seem to have a heat or overfert problem. That isn't cosmetic damage.Nope. Soory, that is not nute burn. That is from the tips of the leaves bapping into the CFL when they stretched. It is localized heat stress. It can only happen in CFL grows.

I wish you could look in the closet in person, you'd see the difference much clearer than mere photos can show: large, healthy plants with scarred leaves from bapping into the CFLs during the "stretch" phase of bud. Check out my tubgirls (http://www.yahooka.com/forum/showthread.php?t=115842) thread for detail on my battle with stretch.

The "curls" are from me adding sidelights. Since lights are now in all directions, different parts of some leaves will orient towards different bulbs. A very, very mild form of "hot spot", I guess. But again, merely cosmetic.

[Volker]

Bleh. Best I could do. Does this really look overfertilized & stressed? You can see the sidelights, which are causing curling, and the bud tops in amongst the CFLs, which I have to be careful not to let the BUD touch the light. Leaves can and do hit the lights all the time.

When the door is closed, that dark area in the lower left does get light.

OK first off this isn't one of my clones this is my 31 day old northern. Just thought I would clear that up first. Now that you mention heat though it got me thinking. After I transplanted I had to adjust the height of the light and the temp went up to 84(which they aren't used to) for a breif point and it was only after that I noticed the twisting. It is on the top leaf after all(forgot to mention that). I'll go check on them and get back to you guys(very hectic morning). Thanks

Volker, check on those red petioles of yours. The plants look okay but there are a few trouble spots... can't see too well because of the odd lighting, but in the bottom right of the pic there's some fan leaves that may be showing def/burn/lockout... better lit pics on those?
