Advice Welcome - First Grow

Transplanted into 5 gallon container, which is the biggest size. Don't plan on growing these too big, just a small harvest. I've started feeding Bio-Grow, starting half-strength from the recommended schedule. The biggest plant seems to have some heat-stress or deficiency, maybe both. The temps have been high, maxing at 31C, which is simply just too high. I've increased airflow in the tent, raised my light, and will be starting seaweed extract to help recovery / prevent further damage. Since I've only just started feeding, the yellowing might also be a deficiency which I hope will resolve itself. --- I hadn't watered the plants prior to transplanting, so the soil pretty much just crumbled up. I was a big too rough with one of the plants, but they both bounced back almost immediately. I don't think I'll be topping this grow, but will probably do some LST during week 2 (or 3!), if all things go well.
