Hydro, Jack Herer fem & Purple Punch fem

Photos are from 11/23/2022. 11/23/22 - ppm range is somewhere from 750 to 850 for 3 of the plants. The back flowering auto is at 550 ppm, adding 20ml of micro to all the plants, 30ml of gro except for the last one bigger auto is 20ml, Bloom is 15ml each except the big auto that’s 30, 15ml of cal mag for all & 2ml of hydroguard. Decided to defoliate all the plants except the flowering auto. For the two plants in front, I decided to top them and try to clone them using a rooting gel & placing it in the aerogarden. I noticed that the stem is a bit hollow for both of them. I'm planning to let the autos in the back finish and then flip to a 12/12 light cycle when they finish, for now, I plan on having a very long veg period. As of 11/25/2022 the ppm of big auto in the back right is 850, ppm of small auto in the back left corner is 1300, ppm of the two fem plants in the front is 1100 - 1250. All ph balances are between 5.5 to 6.0
