Daily watering is done either 4 hours after the plant wakes up or 4 hours before it goes to sleep. My photoperiod is from 6 a.m. until midnight, which means I water either at 10 a.m. or 8 p.m. When it gets bigger, I plan to water at both times to ensure good root oxygenation. Even when it's small, I use a raw ppm (parts per million) reading. From the beginning, I calibrate it to a minimum of 800 ppm and increase it according to the plant's growth. I maintain the pH at 5.8 throughout the entire cycle. Watering is done with 200ml of solution, and the runoff is checked daily. If the ppm rises too much, I perform a flush. This week, the soil's ppm was already reaching almost 700, so I did a flush with 500ml of pure water and calibrated pH. Soon, I will begin pruning, considering Topping, LST, and Lollipoping.
OBS: I have been adding H2O2 to the waterings to prevent gnats and unwanted pests.
Same thing happened to me man... me Hulkberry Auto is MICRo but that's cuz I LST it, didn't even Top my plant.. it just got pissed from me bending her over once. Idk what it is with the Hulkberry but mine is super small too.
