Best way to switch from 18 to 12 of light?
m0useanswered grow question a year ago
change the timer on your next off cycle.
eg if you are on a 18/6 currently, like lets say 5am till 11pm
when it goes past 11pm in its off cycle chnage it to your new 12/12 be it 5am-5pm or 7am-7pm whatever you want.
you can do it slowly over the coerce of a week or two like nature does in 15 min intervals a day but the plants don't care. one stop shot, get it done and over with.
Good Luck!

Hi there
So, as you to into pre flower. You want the most even temp for the 1st few weeks (pre flower) so, I'd have lights come on at the coldest part of your day. And lights off at the hottest. Or whichever way gives you the least temp fluctuation

I’m trying to keep the midnight point when switching to 12/12 by giving the last day of veg several extra hours of darkness and the same amount on the first day of blooming. For example, if the midnight point was at 14:00 (no light from 11:00 till 17:00): the next day I switch off the lights at 8:00, and turn on at 20:00.

18 weeks, but I'm not sure she's ready.The plant is 18wks old. Leaves are getting yellow, some buds are so fat the branches bend under the weight.
I'm worried some pistons are still white and I can still see some clear trichoms, but she's 3 weeks after the recommended date of harvesting.
Do you think she's ready?

3) Exceso de fertilizantes?

Why dont my plants grow towards the middle/light and instead concentrate near the walls?Looks like my plants are growing towards the wall and not towards the middle where the light should be the best.
Why do the plants behave like that and what should I do?
Raise the net, rotate some of the plants, then redo the net?
Remove the net completely?
leave it as it is?

What do you guys think?It's my first grow (automatic, 6 weeks old) and compared to other plants, my plant looks a bit small/ridiculous. I give her 24/7 light (I read that on guides) is that maybe too much? What's your impression of her? I use two growlights (one from above and one from the side).
