Day 29. I adjust the LST to form the canopy. pH at 5.8
Day 30. It's not necessary to adjust anything, just a little the main stem. pH at 5.7. Growing well :D
Day 32. I change the water in the tank, I go from the vegetative table to the flowering stage, keeping the same Ec pH to 5.9. I make some small adjustments to the LST and remove a few fan leaves.
Day 35. Growth is pretty good. The pH drops about 0.5 by day, the plant drinks about 1 liter a day, (I think this is due to the decrease in pH). First defoliation.
In general, the week has been good. Now I have to deal with the daily pH drops I think caused by the water intake of the plant.
Possibly one more week of stretching remains, Auto Mandarina is 70% sativa 30% indica, so an Indica dominance would be better for my set up.
