2 Chrystal Plants 5 Weeks Old

I have these plants growing indoors at 75 degrees f constantly. They are in nice sized pots and fox farm ocean forest soil.
They are huge for only being 5 weeks old. And they are real healthy, lots of green leaves, even some with eleven blades.

My First question is since I gave the plants their first fox farm liquid grow at the date specified on the bag of soil (1 month no more nutes) And the tips of the new growth are alittle burnt, do you think they would do basically the same thing without the nute burn and no more nutes? Or does nutes help to achieve higher THC levels? And if I quit the big grow now and dont use the big bloom at all am I still going to have to flush them a couple of weeks before harvest?

My Second question is when should I go to 12/12? I bought the seeds from Nirvana. It says grow height medium which I was concerned with growing in a closet. I have probably 2 to 3 feet left and am thinking what if it goes thru super vegetation while on 12/12? Also on Nirvana's site it says "Flowering Weeks" "9/11 weeks". What does this mean? Does it mean when my plants are 8 to 9 weeks old I should go 12/12 and harvest at eleven? Or does it mean that whenever I start flowering that it will have to flower for 9 or as much as eleven weeks? I really need to know.

Also I included a pic of one these plants when it was 4 weeks old.

TIA

Plant looks great, sure a small amount of nute burn.
Here's what you do. Top it down 2 nodes. That will make the bottom branches grow up and even out on top, also that will keep you from having one main stem way above the rest in 12/12. I urge you to do this being height restrictions and your plant will yeild more and Beautifully.
2nd After topping wait 2 weeks then go 12/12
3rd Make sure you keep up with the nutes, easy though and switch to Tiger Bloom 2 weeks into 12/12 and 2 weeks before harvest flush.
When they say 9-11 weeks, thats 12/12 weeks.
I would say that is a 9 week strain judging by leafs.

?#1)FFOF HAS ALL YOU NEED FOR 1.5 TO 2 MONTHS then I use Organic guano teas. Guano is what makes OF so good so it is better to stick with the guano VS FF NUTES IMHO ya she is a little burnt do not feed her the next few times around
?#2) You better flower now or you will have a jungle. You will prob want to SCROG if you only have 2-3 feet left of grow space. how big are your pots

I would pinch not top, and by pinch I mean cut the top 4 fan leaves off, this will slow the top shoot without stunting the plant and the side shoots will fill into a bush.

Thank you very much for taking the time to help me. I don't understand what Topping it down 2 nodes is? And did you mean that after topping it down 2 nodes I can go ahead and start 12/12 today. It just seems alittle crazy when the plants have been vegging for only a week.
TIA

The leaves on the plants are several with eleven blades and I dont think there are as many with nine. I dont know if that makes any difference in when I should start the flower or not?

If the plants are five weeks old, they've been vegging for more than a week.

The number of blades on the leaves means absolutely nothing.

9/11 flowering weeks means, once you switch to 12/12, it will take another 9/11 weeks for them to finish flowering. I would do it pretty soon - once in flower they will double or even tripple in height - so you're going to run out of room fast. Look into LST for sure.

There are a ton of great threads here that will teach you a lot just by reading, spend some time browsing the forum and see for yourself.

Good luck!
