How to handle burnt new growth from CFLs?

Overnight, the new growth on my tallest plant stood up very straight and ended up touching a 26w 6500k cfl. This si the third day since then and the new growth is weak and wilted looking but is still growing, although slowly and leaves are still thin and twisted.

Can I do anything to help them out? Should I trim burnt tips on sensitive new growth and is it ok to trim dead tips on old growth?

As long as I am talking about trimming, I have some leaves on that same plant that are curled down and inward and are blocking light to undergrowth. I know fan leaves take in energy, but should I remove a couple of those curled leaves? On my healtiest plant, I have a great deal of nice secondary growth underneath a gang of healthy fan leaves that could use some light from my 55w bulb... shold I remove a couple of those healthy leaves to benefit the undergrowth? I just switched to RO water from distilled and started Cal-Mag(already using Dyna Gro Grow and Liquid Karma which I have adjusted their ratios) a three days ago and the curling and slight nute burn seems to have stopped on new growth, but I am not sure if it would uncurl those curled leaves so more light can get to the undergrowth.DSC01038.jpgDSC01039.jpgDSC01041.jpgDSC01036.jpgDSC01035.jpg

Those still in veg? If so I'd just top it so instead of it repairing the burn damage it will direct energy to two other shoots making two tops. You can just leave it alone and it won't make the leaves look better, but it will continue to shoot up unless the top is so damaged it stops producing new growth from it, in turn should direct the energy to the lower branches just like topping it, but probably not as productive(holy runon batman)...

In a nutshell its up to you...it will recover eventually, but its up to you if you want to top it to make more colas or leave it be for now and just let it ride out the damage :)

Tomorrow will make six full weeks of veg and I JUST started flower cycle last night. Does that mean I should not top it at this point? If I can and do, where should I cut... right near the node where the burnt new growth shoots start? The freshest new growth, although of course still small, is a little weak looking and leaves are thinnish but not burnt and look to be on their way to growing decent. Hard to decide whether to top(if I can at this point) and just start new shoots or let this damaged growth fight through since this plant, although the biggest, has always been the more unhealthy of the three. I'm hoping the addition of Cal-Mag sets some shit straight and it seems like it already has.

It's best to let a plant recover from stress(burning/cutting/pruning/topping/LST/etc) during its vegitative cycle so when you go into flowering it doesn't have to repair itself and can focus on giving you flowers and resin...you can stop the flowering cycle no problems right now by just putting it back to 18/6 since you just switched it yesterday. There are plenty of tutorials on where to top/how to top around on the forums, but being 6 weeks into veg already how much longer do you want to keep it there? If you are going to top its probably best to let them veg for another 3-4 weeks to recover from it and start beefing up the side shoots. If you just want to finish it out then just leave it in flower and let it run its course and next time you can use some training techniques to increase your potential yield :)

Yeah, I think I'm going to just leave it alone and let it run it's course through that bit of burn. I'm not going to wait another three weeks with vegging, especially since I'll bet that particular plant, stressed as it has always been, will end up male anyway. This is my very first grow(hydro at that) and things have gone fairly well and trouble free so I can't complain. This has been great practice for the next time.

Id just leave the bud and let it grow the way it would normally, but massah is right it would be easy to top it and just let it get another month a veg since you just barely began frlowering it. Somthing ive noticed about the small watt lights are if you have a stronger fan (i used a square box fan) then the lights can touch the plant without burning.

Ha, interesting, but I'm still not going to chance that :). I have one 55w, three 26w, and one 23w on three plants all growing within an 18x14 space. I have the lights as close as possible, about 1-3 inches away.

Theres nothing wrong with those plants that won't fix itself after a few days. Yeah the tips are just barely burnt and they will never repair themselves but the burn is so small it's trivial. Personally, I never cut off leaves. I let them die off on their own unless they are so dead and burnt from over feeding that they are just getting in the way. Even then I wait until the leaf is ready to fall off. Everybody is different and you should do whatever you think will be the most rewarding. Cannabis can take a beating and still produce great results. It won't hurt anything to take a few leaves off. It may slow growth a tad but not enough to really notice. It's your choice in the end.

All in all, you're doing great man! Keep up the good work. Do you have a journal going?

That's what I'm thinking, I hate to cut any healthy, energy sucking fan leaves. I guess I'll just keep my lower lights adjusted to keep hitting the secondary growth. I don't have a journal but there are several pictures in my posts that basically chronicle my grow. I do need to start one.

Maybe you could try out LST! Once you go LST, you'll never go back. LST will get those bottom leaves plenty of light.

I was trying to keep it super simple for this first grow, but LST seems so simple, I just might do that sometime today or tomorrow. It's just leaning and tying down as many upper branches as you can safely do, right? Is there a good video or tutorial with pics that I could be directed to?

It is extremely easy. I never understand why people post LST threads in the Advanced Growing section. It's really a piece of cake for anyone to do. Virtually impossible to screw it up aside from attempting to tie down too thick of a branch and having it snap on you. And really, what is a screw up anyways? Just a lesson that needed to be learned ;)

yarly...its not hard at all...tie string to stem loosely...attach to pot pulling gently...increase tension over a few days if needed...its not rocket science :D

Yep, I gotta quote myself.

I knew it, just started flowering and already he couldn't wait to pull his dick out. I know that pic isn't clear because I stink at getting up close, detailed shots... maybe it's my camera, but aren't hose are balls? There is a little round ball on the right side that should be clear enough and there is a second half hidden on the left. Is this definitely male or should I give it time? The roots are somewhat tangled with other plants at this point... how should I remove a plant without damaging the root system of the others(assuming it is male).

I am now sick to my stomach and have no appetite. lol jk Sorry man, wish there was something I could do to take away your pain.

Don't take this as confirmation. I can't really see well in the photo to judge.

I think I better give it a few more days. Do female preflowers ever appear roundish when they have JUST started forming? They are brand new and might have a slight onion/pear shape... maybe. There are two magnifying lenses around this house and I can't find either.
