Mold infested stem? Please help me

Hey guys,

It's week 9 into veg (I had to extend 1 more week because I broke the top 3/4 of the stem & I want to let it heal before going into flowering), and yesterday I switched from fluorescent to a 400W HPS.

With that much light around, I was horrified to see the bottom part of my stem be what seems to me eaten by mold.

This is my 1st grow. My little baby is a C99.

I cut the first 3 nodes because they seemed dead, and a few leaves were covered with a white powder that seems to me like mold.

The rest of the stem looks very healthy, but this bottom part looks scary.
I think it's because the drooping system (the brown circle) sprays it with water.

Is my plant going to be okay? Is it going to be smokeable?
I'm really worried, I invested so much heart into this, killing her would be like euthanizing my own child.

Thanks for your help!!

She will be fine. Get some neem oil spray and give her a good dose of that after you gently wipe the white powdery mildew off. Neem is both a preventative and a curative for several species of bugs/mold/mildew. Happy growing!

Thanks! I'll buy it right away.
By the way, should I be worried about dying leafs at the lower nodes?

And one more thing - I broke the stem trying to tie her down, so as I was advised by the kind people in this forum I taped her up and tied her to a stake. That was a few days ago and she almost recovered completely. But now that I switched to a 400w lamp I tried to bend her a little and tie her again so she doesn't come close to the light, but she broke again at the same point as last time. Can she recover from a 2nd break at the same point?

man I wouldn't count on it being fine, you're just opening yourself up for root rot and or fungus gnats, keep all vegetation out of your rocks at the very least. Forget the neem and get some h2o2 and sterilize that shit.

neem? in the medium? really?

Yes she can. Here is a pic of a young girlie whose stem was munched in half. She is growing strong and repairing at a 90 deg angle. I'd wait a week or so under a veg cycle to let her heal. Before and after shots.

That shit looks way too wet at the stem. You might have stem/root rot as the rockwool is probably staying soaked. That stuff sucks in my book. That thing should be way bigger for 9 weeks. What is your feed schedule? What is the medium- just hydroton with the rockwool or anything else? Is it always that wet?

My local store doesn't sell h2o2 so i'll go with the neem
Keeping my fingers crossed.

BTW does it hurt my baby if I cut her dying leaves?

really? neem oil ? in the medium??

uh h2o2 is everywhere man, the 7-11 got it.

plants luv it, now neem I can't see how they'd like. In the medium anyway.

Yeah it's really wet. I feed her for a 15 minutes drip for every 1 hour, during the 18h period only. The rockwool is really wet. I'm just realizing now that my medium (a 30 liters pot) may contain a water level way too high than I need.

Can I treat stem rot?

BTW she is quite tall I think - she is about 80 centimeters tall now.

Really? 90 days??? :/

so I guess you may as well put neem oil in the reservoir like the dude above advised eh? Not me. Get some h2o2 at the local drug store, the 3 percent is fine just make sure it has no perfumes or additives.

Whoops, she not 9 weeks old by 8 weeks - today is her 60'th day birthday.
I really hope she's not going to die on me

dbkick, can you tell me exactly how I treat her with the h2o2? Do I need to add it to the water? I'm a complete noob.

hope you can kill it cause its systemic. id agree on the food grade h2o2 treatment too kill the pahtogens. if you use any microbe it will kill that off to but can be replaced

Hey guys, I'm back from the store with a 3% H2O2 bottle. It's 100ml.

How do I use it to heal my baby?...

3%????...real week.usualy its 29% we use. and off top of my head i think for the stronger is about 1 or 2 ml per gal
dont get it on your fingers or will burn and bleach them white...the 29% does not sure that will being weeker

Yeah sorry. At the doctors office you could do a pint pet 5 gallons safely I think. And yes the 29 percent will hurt you and it mixes a 2-3 ml per gallon as stated above
