December 30th:
Finally installed the Hortilux 1,000w HPS bulb and ballast, during this week. I decided it was time, since the plants finally simmered down on the stretching side of things and started putting on flower mass. It is set at 50% on the dimmer at the moment and I'm going to gradually dial it up to around 75%-80% throughout the rest of flower.
I've been feeding them BuildABloom every other day, now. I'm going to continue doing that for the next 2-4 weeks.
@Ju_Bps, thanks, friend.
I'm bummed the timer melted and I didn't notice until the leaves changed. I got comfortable and lazy with this set-up, so I've been making sure to check on everything at least once a day. I learned a terrible lesson and I don't want to repeat it!
