Fast Buds Gorilla Cookies Auto Indoor 4" x 2" Grow - Mars Hydro FC 4000

The Gorilla Cookies grew taller and bushier. I started to LST her on day 15. Every 2 to 3 days, I renewed the training stakes and gave her new LST. I broke one the bottom notes (picture 3) off but since the where 2 branches lower they just replaced the one node. I only fed her once a week, this week it was on day 20 with 1ml/L of BioBizz-Grow. I also set the light to about 60% power on this day. I didnt knew it, but I think this is where my problems started. I didn't add calmag to my water which later turned out to be a problem, because I gaveher very much light intensity and she was going through the calmag in my tap water very fast. Especially in midflower her calmag need was very very high.
