How am I doing? Day 35 flower

My babes are about 2 weeks with some visible flowers, how long does it take for them to fully grow into buds? I am day 93 into my hydro grow. Day 35 of flower.

Also can I put both plants in one bigger container? I have had them seperate the whole time but to gain a few inches in my setup I have to move them into one larger container to share water and nutes. Is this safe? They are two different strains and I don't want to damage anything but I will gain like 3 inches in head room because my one plant is max out.

I think they look abit burnt to be honest. A HPS would be an advantage because I see mostly pistils right now. Lots if foliage also which would be counteracted somewhat by a more powerful light. But they don't look too bad.
