Window Sill Auto Grow

Week 8 Our evil Landlord had a Problem with the plants on the sill. She made the suggestion to put them on the shed roof in the backyard.. but that would be illegal because they have ro be inside the flat/not reachable for others. We put them on the sill behind the window on the inside for a few days. shortly after I spotted powdery mildew on one leaf.. and it progressed.. a few days later we removed some leaves and started to treat the leaves with milk. And we got predator mites for the thrips infestation. Bili ordered a 4x2 tent, 6 more LEDs with not so good quality in 3000k. (they sent the wrong model) We now have 9 bulbs with a total of 159w So from now on we finish them indoors. It sucks because they looked massive for a sill grow so far. Some people still don't accept that it is legal now it seems. The PH problem/nutrient lockout progressed. too much yellowing. We initially decided to guess the amount of ph down (when the ph pen still worked we figured out that 5ml/10l makes a ph of 6).so we wanted to bring the ph down with ph'd water. but billy was too stressed out to remember and watered with just tap water and topmax/mg. next watering we will give them a good dose of (guessed) ph 6 water.. hopefully this will help.
