Indoor When to switch from mh to hps? Auto assasin, and himalayas (250w)

[159]

I have 3 plants here, Blue himalaya, Blue himalaya diesel and one auto assasin.
Auto assasin is in front, and then two BH and BHD behind. In close ip you can see the biggest plant, they all have white pistils now.
Can you tell me is it time for switching to hps lamp?
Thx

1st time grow btw, they looked pretty sad at the start, yellowing leaves, all the time droopy, but now it went the right way.

also another question, do i still need feed them nutes for vegging or i need to start use some bloom nutes ?

Yes, the hps is very diff color spectrum be sure and keep ya cat away from ya plants as cats will urinate in the soil if given any chance at all.......... with nutes, just begin blending in some bloom....Looking good with ya 3 ladies....

heya, my cat is only there with me, i'm watching him, after he ate one bagseed seedling i don't trust him anymore
ok, so i will add bloom nutes in next watering, gonna use biobizz bloom nutes.

Autos can be grown full cycle with HPS but since you have the MH, I would use it through veg and preflower, then switch to the HPS at week 5 or 6. Even though buds appear at week 3-4, there is still a lot of veg growth through week 6. At that time I would also suggest switching to bloom nutes.

I would keep kitty away from the garden at all times man. At a minimum you'll wind up with cat hair in your buds. My wife's cat once got in a boxing match with one of my plants after sneaking in the grow room. Pretty much destroyed close to an oz of what would have been good nuggets. Although I didn't go after the cat since she's just an animal and didn't know any better I really had to supress the rage on that one.

alltho they are "pre-flowering" they are still growing vertically and need N to continue proper growth. once they stop growing vertical(6-7 weeks) they are in full flower and can be given bloom nutes.

thx for replies, pictures from today, changed back to MH lamp.
one more question, can i switch cycle from 20/4 back to 24h straight? because it's getting colder and light can heat up that stealth grow pretty nice.
some pics from today, I watered them like two days ago, now they look a little bit droopy, dunno why actualy, gonna get my water ph meter in some days, still don't have it.
