Getting hit with a burst of "there's cannabis growing in there
" smell at lights-off is not unusual. Especially if the exhaust fan is tied to the light timer and shuts off at the same time.
I thought I saw just a bit of upward leaf curl on the serrated edges of some leaves in recent pictures. What is the high temperature at the top of the plants? It could be a sign that things are running just a wee bit hot. (Is your humidity high?) Is there also a bit of yellowing on the newest leaves? If so, the two things could be indicative of a
slight bit of a potassium deficiency. Or (possibly) that plus a little too much nitrogen (does your calcium supplement also include nitrogen?).
On the other hand, I'm nearly blind as a bat, lol, and also have color perception issues - so I might be imagining things and your plants are in perfect health. They certainly don't look "ill," regardless.
By the way, congratulations on getting the new light! I was sort of hoping I'd get to see your plants go all the way to harvest under - only - the TS-1000. However, I do understand that little lights produce (relatively) little bud, and that more lights... Well, you know. My most recent lighting acquisitions are a TS-1000 and a pair of SP-150s, and I'm thinking that I'll really need all three to optimize my tent - but I was also wondering how well the TS-1000 would perform on its own, just in case I end up being able to run only the SP-150s (or those plus one of the other lights I have here) and had the opportunity to stick the TS-1000 by itself somewhere. Or... In case I find myself worrying that I won't be able to pay the electric bill at some point this Winter and start thinking about trying to "just keep alive" some plants with only the one light, I suppose. IDK.
