Do you guys think it would be alright to stall to stay on week two for three weeks in total to catch the little guys up?
If you have a plant(s) that are thriving more than others, you can't really cut nutes to hold them back. You'll get nutrient deficiencies. You'll see some ca def, nitrogen def, etc. Same things you'd see if overfeeding and salt build up. (I tried it once, trust me.).
If you want to keep the height uniform you can engage in low-stress training (LST), or "super cropping" which is more extreme. Or, "FIM" to force vertical growth to occur in lower branches. Or, "topping" or mainlining which is topping with training to hold the lateral branches down creating more of a candelabra appearance.
