Plants are still in bloom

[AandKdaddy]

My plants are still in bloom stage and aren't showing buds yet is this normal? they have gotten very tall now...look like they are showing alot of pre flowers tho...I switched the light cycle about three weeks ago...although I did mess up on the cycle a couple times...could this be why they aren't blooming yet? I finally put the light on a timer..hope this works?

also my rubbermaid tub looks like a huge pot of spaghetti with all the roots I think I should have kept trimming them back ...Is it ok to cut roots back now or just leave the alone till harvest....there is a lot of small root particle floating in tub as well...from emtying and refilling res...I added another duall line air pump due to all the roots sitting in res... are my plants going to be ok? I think I only have 1 more month till harvest?
