Black Sugar

On 10/01 I switched from a 24 hour light cycle to 18/6 light cycle. I slowly increased the LED light wattage from the starting point of 80 watts, to 150 watt on 10/3, 225 watt on 10/04 and today it is at 300 watts. Tomorrow I will be removing the LED and installing a 400 watt MH hood light. I am going to start that one around 200 watts and slowly bring it to full power as to not stress out plants. I've been hand watering just enough, every other day, around the base of the stem to wet the soil around the tap root. I will begin a full water schedule this upcoming week. I am rotating the plants positions daily because I think it might help strengthening the stem by slightly moving them in the direction of the light. Its most likely not helping at all but I also don't see any harm in it. I added a small fan just for air flow and turned on my vent system at its lowest setting.
