Amnesia - Ganja Farmer growth test

Hello mates, here the second week of vegetation. The plants are very healty and, i think, ready to some HST so at the same day, the first of the week, i do topping at the fouth internode and i pruning a little in the lower part for both. How you could see from the photos, after four days the the plants cover the area of the vase, i think that they reacted very well. I continue during this week to nebulize those with the solution with neem's oil and potassium soap (10ml/L of water each) because i can't get rid of the thrips ( yes, unfortunally i only saw now they aren't fungus gnats) in fact I added also the chromatic traps. I did watering twice in this week: - 0.5 L of water + 2 drops/L pH-down (x2) T 22.6°C - 131 ppm - 0.26 ms/cm - pH 6.34
