Top and flower more?!?!?! Or no?

heyy im at week 9 in coco, tops look great but 60% of buds are premature. Tried Scrog net and used to early, so it really didnt do its job. I have 9 plants in a 4×5... already flushed half 2 times... so my question, can I cut tops to make even canopy and get rid of yellow leafs. Then nute and flower bottom half for 2 more weeks until my veg is ready????? Will they mature anymore after cutting most tops?

They definitely stop doing anything when you flush. Too late to top and it’s pretty much too late in general.

you will find that top colas are finnished b 4 the lower ones, so by topping the main cola out now, the lower colas will get some extra light and they will finnish later on. but as hotrod says, you stop feeding them and theres no much nutes for them to work with
