I'm growing Jack Herer Autoflower. The older leaves are yellowing, and now some of the newer leaves are also starting to yellow. At first I thought that the light was too close to the plants, but I moved it so it's about 3 feet away from the plants. I started germinating them on April 23, and these pictures are from today. They seem to be stunted, but maybe I'm just expecting too much from them. For the last 2 weeks I have been using Cal-Mag (2 ml per gallon), and Botanicare pure blend pro grow (10 ml per gallon). This drops the PH of the water, so I use the general hydroponics PH control kit to up it to btwn 6-7. The humidity stays btwn 45-60. I am having a tough time getting the humidity to increase. The temps stay btwn 70-75.

I'm sure it's a nutrient deficiency somewhere, but I'm not sure where. I read about nutrient lockout, and I'm tempted to say this is what my issue is. I flushed the soil tonight, just to see if that could help. Does anyone else have any other suggestions? If you need any other information from me, I will do my best to answer it.
Thank you!

I think it needs to be transplanted into a bigger container with more soil. I would add some perlite to the soil mix too.

Thanks! I was planning on transplanting in a day or two anyway. I’ll try this first and any other suggestions I get next.
