HELP!!! I got problems

[zacmaster]

Can anyone tell me what this is. It has happened to pretty much all the plants. The yellowing starts at the older leaves and keeps working its way up. They are growing in soil and we have been giving them a kelp mixture each watering and use 20-20-20 once every weak or two.

Looks like you're in need of a transplant. When these plants become rootbound, the roots aren't able to absorb nutrients as effectively, which can cause deficiency symptoms even if they're regularly being fed. Take it out of its pot, and if it's obviously rootbound, then get it in a bigger pot.

Take care. :jointsmile:

Thanks for the info, my roommate and I pulled them out the pots to look at the roots and seems to be rootbound and going to buy the bigger pots tomorrow to transplant them. Hopefully this works we were getting worried. Thanks again.

[Mr. Clandestine]

No problem, bro. The bottom leaves obviously won't be brought back to health, but you should really notice the new growth start to take off after a few days of being in a bigger container.

We have another problem also...One of the plants is around 7 inches taller than the rest. I've read that you can bend them over for awhile and that should slow the growth. What do you suggest that we should try to slow the growth to let the others catch up before flowering starts?

[Mr. Clandestine]

In veg you can bend them and secure them with some string, a stake, or something similar... or, you can simply snip the top of the plant at the last node, which will halt so much vertical growth and produce two new shoots at the site of the cut. With bending or "training", the plants seem to get a bit bushier. You still will have a main cola, and you'll also have all the side shoots at the same level and receiving the same amount of light. Essentially, you'll end up with several top colas.

Hope that helps.
