Power Plant Problem Puzzler

OK, so this isn't anything that I'm overly concerned about, but I wanted to throw this out here for any more experienced growers that want to throw in their opinions and diagnosis on it. I'm thinking it is one of two things. 1. I've over watered it or 2. I'm about to burn it with Cal/Mag.

I have a Pure Power Plant seedling that is looking sick. This plant is being grown in Botanicare Ready Grow Moisture, which is Coconut coir, Perlite, Leonardite ore, Earthworm castings, Montmorillonite, and Yucca extract. I've been watering with tap water PH adjusted to 5.8 every couple of days. No nutes besides 1 ml/g of General Hydroponics CaliMagic, and I add 1 ml/g of Botanicare Hydroguard.

Here's the other plant that has been on the same schedule using the same water solution. The reason I added the CaliMagic is from advice I got in Ed Rosenthal's Marijuana Grower's Handbook. He recommends for low testing tap water, you use a Cal/Mag supplement to bring your PPM up to between 125-150. It made sense to me since I seem to always wind up with a Cal/Mag deficiency. My PPM has been from 130-144, brought up from 57 to 65. Its hard for me to think that it is being over done. I have other plants at about the same age using the same solution. PP-2 is the only one showing these symptoms,

What I've done is to take the seedling and put it back in the humidity tray, and switching it to plain water, PH adjusted to 5.8 to see if that helps. Do you think I'm on the right track to get this seedling healthy and growing again?

Thanks!

I think your seedling looks good. Doesn't seem that you are doing anything wrong , its doing a whole lot of downward growing right now. That may be why it looks a little different to you?

well, you're on the right track thinking you're over-watering because relative to the size of pot it is in, you are because of frequency, but i'm not sure why you think putting it into a humidity tray is going to help? take it out, and back off on the frequency of your watering schedule. in the beginning, they need a couple tablespoons of water every day or two but then that needs to start stretching out farther in between with more water as they get bigger. and for now, just use plain water.

Haven't grown one out for a while from seed but I do remember the PPP seedlings being finicky when I did about 8 for a pheno hunt. 1st one looks maybe over-watered, second one looks fine imo. looks Just keep an eye on them but I wouldn't do too much at this point other than keep an eye on them, some seedlings can be a pain in the ass until they root/establish and fine after that.

undercovergro, well spoken.

Jimbob, just to offer some clarity, the humidity tray is used to get clones to sprout roots, not for putting already germinated seedlings into it.

The little starter containers you get when you buy cucumbers, tomatoes, etc, those work nicely on seedlings. Once they get a little bigger than what you have, put them into a larger one...On the grand scale what you're gaining by doing this is control. Control over what's going into the plant and the frequency of these activities. Growing hybrid cannabis has become such a picky, finicky endeavor. They are a very demanding plant species.

Yes, it is the curled, or downward pointing growth, and if you look closely, you'll see discoloration on that big primary leaf there. I didn't notice it until I put my glasses on and inspected it under the light but it is looking kind of bronzed or copperish looking around the edges.

I suspected that I was probably over watering, but the Botanicare Ready Grow Moisture instructions say not to let it get dry. The recommend leaving water in the tray at a half inch to an inch or so. I haven't done that, rather I would just eyeball it and add water when it looked like it was getting dry. After being in the humidity tray overnight, the downward pointing leaves have perked up and aren't as curled, but the color isn't any better yet.

Undercovergrow, thanks for the input. I'll back off the watering, :) A grower that I have been talking to on Facebook recommended putting it in a humidity tray, or rather, he said I could make a dome out of a soda bottle and put over it. He didn't elaborate on why. However, after it has been in there overnight, the leaves that are pointing at the soil have picked up. I have no clue what that's about. He also recommended that I take it off the CaliMagic for now. I wonder why all the other seedlings in the veg tent are doing fine on it, but this one seems to be unhappy? :D

I appreciate all of the replies! Thanks to you all. I'm a relatively new grower, with only a handful of grows under my belt, so I have lots of dumb questions. I think sometimes that new growers like me get overwhelmed with information, and possibly misinterpret what we've read. I read a lot on the subject, but there's nothing like actually learning from your mistakes.

underwatering and overwatering can look very similar; if the leaves on the droopy one perked up in the humidity dome, then to me that would indicate it was actually needing more water. try to remember to treat each plant as an individual and water accordingly instead of watering/feeding all because you're in there.

there are no dumb questions...well, wait, i've seen a few here on RIU bongsmilie but you're good 8-) :eyesmoke:

Probably over watered. Don't adjust the tap water that low. 5.8 ph is low end for hydro try 6.3 ph I don't think a seedling should have any food for about 3 weeks to a month plenty of nutrients in the endosperm. Ed was probably talking abut ro water lacking calmag. you shouldn't need to add calmag to a seedling.

I think so. It looks better on the newer growth today, no drooping, but the discoloration on the leaf looks worse to me. I'll PH some water to 6.3 and give it a little bit when the pot gets light. It didn't get any water today, and its vegmates got just a couple of tablespoons worth. I think it will get better. All of my other seedlings are OK. Even the other PPP, and none of them have been treated any differently. This one is just sensitive, I guess. :)

Do the ph adjustment for all of them.
