Day 60 Gelato feminized auto from ILGM. There are 3 plants in aeroponics in this 3x3 tent and this is the only plant showing this growth. About 1/2 of the top colas are showing this bright yellow/green area. They are hard and feel like stems. The only thing I can figure is that the colas topped themselves due to light intensity. They are under 3 Mars Hydro ts1000s and the top colas were within a few inches of the lights until I could figure out a way to raise the lights to the very top of the tent. pH 5.7, RH 45%, res temp 65f, around 900ppm of GH Flora 6 part nutrients according to schedule.
