In the northern hemisphere in an outdoor grow you are looking at an early October harvest. So you still have plenty of growing to go. Be patient !

Just keep them in the sun, provided you don't live in a desert. The first picture I think is starting to show a nitrogen deficiency. The bottom leaves are yellowing.

Best thing to do for the plants is dig 2 big holes in the ground and fill them with a good soil mix. The roots will then spread further and you will surely get a bigger yield.

Anyway, looking good. Keep up the good work.
