ok so i have plants in 5 gal grow bags.. and as i was watering today.. i went to pick up the bag to see how heavy it was.. and boy was this thing heavy.. and it felt like it was a big dense bag of roots.the plants are 40-50 inch tall without grow bag..... just wondering if i should maybe transplant to 7 gal grow bags 3 weeks into flowering or not even worth it?
