Eeeewwwwwww. You drink alcohol? Yuck. (Anyhow, technically it's against site rules to discuss any drugs.)
Rarely do I get mad, but I am often...passionate.

Nice to see ya back.
-But-
regardless of the reason, we are all responsible for our posted words. No excuses the next day. "the dog ate my homework" or "I must have been drunk" are not valid excuses. (ok...life lesson over now)

The 150 is a much better tool than the cieling light and incandescents. You can still use the t-5's for side lighting, which would be a benefit. I keep my 1000 watter (enclosed hood, no cool tube) about 20" from the tops. Likely you can go much closer with your 150. I'd check and see how close to the light you can get your hand without disconfort. If your hand can take the heat for over 30 seconds, so can the plants. But best to ease into it over a day or so. This way you don't set 'em and forget 'em. Coming back to crispy buds would suck.

If you start seeking parts for the 150w unit now, you'll know where to get replacement parts and bulbs before they are necessary. (plan ahead)

Old growth is old news. Your leaves won't fully recover, but keep an eye on the new growth. That will be the indicator that you are on the right track. (or not)

You're going to need to feed tham pretty soon, too.

My ladies start to stress under 65ish. Somewhat more importantly, is keeping the difference in low and high temps to as narrow a range as possible. The plants seem to love consistentcy there. Proper ventilation is more important during the daylight hours. It's not nearly as important to vent during the night, as it is to vent during daylight hours.

So homework for the week...

Find an aquarium ph test kit, and some phDown. (freshwater) Do not adjust the ph unless you know the numbers, first.
Get some nutrients with an N-P-K proper for growing cannabis in it's two different cycles. Lower phosphorous for the growth phase, higher phosphorous for flowering. Canna or Fox Farms are a couple with good results.
Check prices for No-Pest srtips. Try and kill 'em before the need for more neem.
(no excuses that the dog ate your homework)

If your soil is holding water too much after a good soaking or flush, you might want to consider adding perlite to lighten-up the soil and/or turn-up the circulating fan a notch.

Good luck with 'em. Glad you got the HID light. You'll want to go even bigger once you see the difference. :thumbsup:
