Purple Punch Clone

Let the ties off when i flowered and the side branching thickened up quite a bit which i didnt expect. Grew 2" this week with one of the branches slightly taking over 80oz every 4-5 days but it has not quite filled out the 2 gal pot. Too much (30%) runoff but hope it goes down next watering Nutes are alternating water/nutes with increase of BBloom for second week and no more BGrow. Might not of needed any of the grow as the soil has soluble nitro but trying to do what the bottles recommend until i do this nute line once.
