They look like the soil is pretty soggy- I am a big fan of drilling extra holes in the SIDES of pots for the roots to breathe. Many problems are exacerbated by mucky wet soil. The runty one looks overwatered.

The big plant showed leaf edge curl from heat stress. I'll bet your deck gets awful hot. But it was still healthy.
stinkyattic Reviewed by stinkyattic on . Genetics problem?? or?? 3 plants all started at the same time, all in the same size pots, and same soil... Miracle Grow Moisture Control feeds up to 3 months (0.21-0.07-0.14). Of the 3 plants, 2 are kind of weirded out, almost deformed, and the 3rd is normal. I am wondering if this is a genetics problem, or is there something else going on. The strain is Afghani Hundu Kush from High Quality Seeds(bought through Rhino Seeds). I dunno... if you need more difinitive pics, let me know. Rating: 5
