Hey bro your grow looks GREAT! I've got a couple 2K HPS grows under my belt, SOG, and mid size plants (around 3' finished flowering height). And weed has always been a simple plant to keep happy and maintain, your doing a fine job.
I did however experience a bunch of problems when I tried to re-veg. My advice to you would be right before you flip the lights to 12/12, try to snip some clones and have a small veg setup.
That's only my two cents though, and I believe other people have had great luck with it, maybe just didn't work out for me. I'd either snip some clones before 12/12 or plan on ordering and growing out some seeds.
Good luck, keep up the great work! Looks like your distance from plant to light is PERFECT, try to maintain it (I can tell from the tight node spacing, heavy branching out, and there is absolutely no heat damage up top).
If flowering stretch has just started [2 inches in 2 days] does that mark the beginning of flowering as the 5th july?
Just wondering when flowering officially starts, so i can gauge when abouts i'm going to harvest.
Flowering begins the day you went 12/12 IMO. I think most people measure it that way for the sake of consistency so we can all have a common "yardstick". [DUH I just noticed you are growing from seed 12/12. So your flowering date is essentially when you planted them. So I'd say your looking at harvest at about 9 weeks from when they sprouted...mayybe a bit longer. You will just have to wait and see how trichomes look at around week 7 or 8. I wouldn't think an Indica like NL would be much over that. ]
Stretch period variesd but you are obviously in it now if that plant is growing 1''-2"/day. Mine grew from 18" to 42 inches in about 2 weeks then began to slow down a lot. Final height was 48" on two of them and about 44" on the other two. I let mine veg too long though. Big plants don't necessarily mean bigger yields. I only got 7.5 oz from my four plants, although they were huge plants that really "looked" good.
How long they stretch and how much is somewhat strain dependent. Sativas stretch a LOT more as a rule than Indicas do. Other factors include, but not limited to: nutes you give, light intensity, color, distance from plant to light, temperature. Your plant will probably double in height, maybe more. I would keep your light as close as possible without burning the plant. And you might want to LST your plant to keep the plants canopy as even as possible. A 250W lamp will not penetrate down to lower nodes/buds very well.
Good Luck

Here they are at day 59 of flower(59 days of 12/12) about a week before harvest.
LSTing a plant isn't hard. Where to tie it depends on the plant and how much room you haveUse something that won't cut into the plant. The big flat shoelacing is good. The idea is you want to bend the plant over gently so lower nodes will ber exposed to the light. The plant will then have more than one "top".
Use the search function for "LST" It is tedious to look through all the threads that come up but there is some good info on LSTing out there
