I don't think as many people read the grow journals as they do this section so I'm moving a post from my journal here: The yellowing on my plants was spreading a bit, so I decided to take action today. The single leaves on the bottom are yellow, and dead I think, but the plants are both beginning to yellow a lot around the outside of their leaves. Here are a few more pictures of them. I think they look worse in person, then they do in the pictures, but here they are anyway. I gave them ferts for the first time a few days ago, but today I just gave them water, with hydrogen peroxide, and a bit of epsom salt, in case the yellowing is from a Mg def. Hopefully this will help cause the ferts didn't seem to have much of an effect on the plants, that I could notice anyways. I don't know hoe to post the pictures here after they've already been uploaded to GC, but here's a link to my grow journal, please take a look. http://forum.grasscity.com/grow-journals/121910-first-ww-grow-2.html Any suggestions would be appreciated. I don't think it's nutes anymore, and the temperature in my cab is a consistant 80 degrees. I checked my soil ph the other day, before I added fert. and it seemed right on. I know ferts can mess with the ph, but the problem doesn't really look any better, or worse, so I'm assuming it's still good.
You need to get a better digi-cam, or set it to take bigger pictures. It makes it easier to see the trouble accurately. It does look like a magnesium deficiency, so the Epsom Salts you gave it will have helped. You can also foliar feed (1/2 tsp / gallon) for a quick fix, but I'd leave it now that you drenched the soil with it. I dunno about hydrogen peroxide. In hydro it's a good idea. In soil, probably not; it will kill beneficial bacteria as well as the bad ones. If you shake your water bottles for a while, the water will be plenty oxygenated. Remember to let the soil dry out between waterings. -mu
Thanks for the response -mu. I know I suck with my camera, it's new so cut me some slack....lol. Anyways I'm hoping in a couple days they will be back to a nice forest green color, and I have been careful about how much water I give them. I know I've read that giving the water a good shake will aerate it some, but from what I've read H2O2 is fine to use in soil also. I'm pretty sure the post I read the person said that they use it every watering, though I think that may be a bit much. Again I thank you for responding, and any other input on the grow will be appreciated. Peace.
Not sure if anyone cares, but maybe I this will help someone down the road.....lol. I repotted my plants, and realized that even though the soil felt dry, the bottom part was still very damp. From here on out I would just reccomend lifting pots to check if water is needed. Also even though the plants are still young, the roots already looked very cramped in the pots they were in. Since I repotted a few days ago, they are both taller and yellowing has gone down signifinitly (sp.?) Anyways if anyone's interested keep an eye on my grow journal for updates. Peace.
