good job that a big stretch either you are doing nutes, right on the money, or you have a genetic freak; either way ride it out. and you are right, when pots feel light, water them. I weighed my pots when a 3 gallon is wet it weighs 10+lbs when it got lite it weighed just over 7lbs. so just over 3lbs change, hopefully you can apply that to you. You might have to do lst or scrog to spread out the large calyx sites, and allow the Fan, and sugar leaves to help in the Photosynthesis. good luck
