Light Damage? - Cannabis Infirmary - International Cannagraphic Magazine Forums

Hello there,

About two days ago I transplanted some well rooted (reads: OVERLY well rooted) TH Seeds Bubblegum clones into their respective deep water culture buckets. They were running on zero nutes for most of their lives, but got about a ML of micro, bloom, dark energy, and supernova per gallon last week while still in the cloner. Now, in the DWC, they have approximatly 800 ppms of lucas at a rock solid 5.6 PH complimented with dark energy, supernova, and supercharger (the latter three at half strength) all at a maintained 70 *F res. temp using only RO water as a foundation.

These plants are under a 1000 watt agrosun MH for vegative growth. They exhibited some curling of the leaves when first placed under the light. I wasn't exactly sure what it was so I left them for another half day or so. Then I realized it had to be the light being too close. It was between two and a half to three feet from the tops of the clones. I just (painstakingly) moved it up to just over four feet above the tops last night. I now believe the light should not present a problem. I know its too soon to see dramatic improvement, but the plants are still looking a bit ratty. I was wondering if anyone could take a look at these shots and confirm that it was light damage, so that I shouldn't be looking for anything else. I took a peak at the roots and so far they seem unphased, with the tips beginning to push through the net baskets.

Does it look like they will heal okay?

NOTE*** the plants in the following pictures look as though they are bent over or wilting. This is not the case. If you can imagine, in the jerry rigged cloner I had the stalks were laying on their sides. Conciquently, they rooted horizontally, then bent 90* and began going vertical again. When I placed them in the DWC, the stalk obviously had to face downward, with the bulk of the plant going horizontal at nintey degrees. There are no problems with the stems, just pay attention to the foliage and gauge from that.

The last photo there (if you look carefully) displays leaf margins curling up on themselves, which, if I remember properly, is a sign of light stress. I havn't had this problem in some time so I do not recall the exact symptoms. I believe I caught it early enough so that there was no burning, but the leaves kind of curled in on themselves. Hopefully this will straighten up within the next several days on its own accord.

Any input?

Thanks for your time.

Here are some more shots from today, and with a much better camera. As I said, there are no signs of improvement. Trying to determine if this is def. light damage, or whether or not something else is to blame. All other variables were and are completely within norms...so the light is really the only thing I can point the finger at...with perhaps some transplant shock factored in.

Potentate · 03-24-2006, 01:07 AM

ok, they are def. looking worse today then they were yesterday...and this is with the light up. In addition, the PH has risen from 5.6 to 6.2 and there is a slight odor in the res...i dont know if this is from a disease setting in or what but im pretty distressed...any help would be appreciated.

Potentate · 03-24-2006, 01:19 AM

Okay, I took off one of the nastier looking leaves...see anything indicative of some type of problem? I'm going to change out part of the res with straight RO to lower PPMs...maybe there is a chance Im running toxic.

Bummer, it looks like no-one cares!

Not light damage, that happens very rarely, and all it will do is cause white, bleached out tissure, most offen associated with buds that grow too close to the lights.

I dunno WHAT that is goin on, prolly some disease, DWC can be a bitch, it can also be great, I might reccommend trying a simpler technique first, then step-up to DWC?

Sorry, I dunno WTF is wrong with them!

Potentate · 03-24-2006, 01:59 AM

Ive been doing DWC for a while now...first time i tried it sucess, second time sucess...now im having troubles...damn

mace_ecam · 03-24-2006, 02:24 AM

whats your conversion factor?

Potentate · 03-24-2006, 02:37 AM

im nearly positive its .7, but ill check

Potentate · 03-24-2006, 02:49 AM

yea, def .7 I believe I'm beginning to see signs of root rot (slight, fishy type odor). I've added more hydroguard, lowered the chiller to 66 degrees, added a few gallons of fresh RO, and crossed my fingers. I really do not want to deal with a crop failure here, but if things dont start going on the upswing within the next day or so I'm going to have to cut my losses.

I'm hoping what is going funk in there are just some of the roots that got a bit mangeled in transplant. With any luck, they'll pick back up, as they had an enormous root system going in. Well, i guess I have to play the waiting game now.

I should note that the first time I grew DWC was with this strain, TH Bubblegum. I must have had a flaming case of root rot at the start, because the room that they were in stunk to high heaven. However, they pulled through with a little help from yours truley, and went on to become the finest plants Ive grown to date. Hopefully these will be a repeat of that experience...one never knows.
