Northern Light Automatic - GHSC - My First Grow

The two fast growing plants exceeded the maximal height I thought for them would be 120 overnight, so i decided to bend the main stem a little bit down and I accidentally broke the main stem of one tall plant. Fixed it with breathable tape and waited for everything to heal up. A shame at this point, though completely my fault. Otherwise I am very happy about the two plants growing way higher than I initially thought. Both are going into full flower without changing any light (This is good because the other two are still fully in the vegetative growth). I started giving the taller ones the first nutrients too, just basic canna terra flores 5ml/l The two smaller, low stress trained are growing even slower but are getting so much bushier. Also they don’t show pretty much any signs of flowering, just slower growth all in all, no nutrients are given at this point, next week is planed
