Leaf browning in mid bloom

I have a few issues with these 2 plants. They are showing leaf curl and browning on the older fan leaves. I dont think its due to overwatering, I am feeding them 5ml per 2 litres of water, Thrive Tomato liquid ferts. They have been budding for 2 weeks but they seem to be slowing down now. They are on 10/14 light cycle. Yes one is male and yes i want seeds so that is why its still alive. Attached pics for any comments.
The plants have suffered a bit of stress in a recent house move and some of the smaller stems snapped but I have tied them up and they look like recovering. Dont know what else to do. Any help welcome...
