Jelly Donutz - Why not?

Another solid week with visible daily performance. Plants are showing some yellowing and wilt on older growth, likely with the changeover to TigerBloom. 2 of the plants seem very stemmy with flowers as puff balls, which I am hoping to see expand and grow over the next 4 weeks. The one single untopped plant Lemon, seems to be growing normally and thicening now. No sign of rot or foul water, been very good keeping temps low this run. JR is the youngster here and we started flowering her at 21 days in. She is skinny but started showing flowers this week. Lemon is untopped and appears to be a normal plant that will have a massive cola surrounded by 3-4 large towers, ea at 1/2 oz top once dried. Tri-Leaf turned into a monster, with huge stems reaching to the light. Had to behad this one at the mail cola to slow down the upward growth and seemed to be successful by pushing back growtime an estimated week. No big changes this week, stable temps, PH, EB betweeen 1050 (b) and 1300 (a) with 2 feeds/week. The next couple of weeks should be exciting wth growth
