See why the form is so important.

You MUST check PH. Shoot for 6.5 as the goal.

This is such a small grow area I am not competent in this. Need someone experienced in these small grow box setups to chime in. I concern about the amount of air exchange.

The plants are showing need for nutrition, should not be that yellow at 12/12 for only 2 weeks. Can you repot into a little larger container with decent potting soil, MG only as a last resort. That should provide most needs, give a very, very small amount of nitrogen, which you probably gave with the MG nutes, so hold on that.

After a couple weeks in larger containers you might give a little unsulphered molasses.....a little.
WashougalWonder Reviewed by WashougalWonder on . Another Yellow Leaf Problem! :stoned: I know its another yellow leaf problem but I have yet found a definitive answer for my plants... As you can see from the attached pictures I have two plants with the same problem, some leaves are turning completely yellow, others are on their way, while a few remain completely green. The yellow leaves are not dry! Our indoor grow area is a 1.6ft X 1.8ft X 2.6ft converted old dresser with white painted inside walls. A 150 watt light hangs above with about 4 to 6 inch separation Rating: 5
