Should i start flowering these?

The taller plants are right around 45 days old. The smaller plants are about 24 days old or so. They really have not grown much since i transplanted them about 2 weeks ago.

i was thinking about topping the 3 small ones so i can maybe get some more growth when i flower.

Two of the plants are 25 inches tall and i will have to move the light soon.

let me know what ya think i should do.

if the nodes are alternating,she is mature enough to flower

should still be growing quickly, u got a fan blowing on them?
could be drying out the leaves?

i have a large fan blowing on them. They are a sativa blend. I planted the 3 tall ones in the 3 gal pots 14 days from seed, they became nice and bushy fast. the others were in the dixie cups for about 21 days then transplanted.

Im just not sure if i should start flowering now with the others being so small.

@VICTORY - sorry this is my first grow so what do you mean by that.

the leaves that come off the main stem when young grow directly across from each other,when mature,they will alternate

u could try topping the big ones so the smaller ones catch up, and try blowing the fan at the light not the plants?

ive started to flower my kush straight after seeding stage, these buggers never stop growing all threw flower!

their ready to flower. Keep in mind that plant double and sometimes tripple size during flower. Over vegged plants will lack vigorous growth.

The nodes are not alternating.. They are symmetrical with 2 stems on either side of the node.

I have not used any nutes as of right now. I did water one time with foxfarm grow big but had nute burn so I flushed them and have just used ph'd water.

Switching them to flower I just need to swap in the MH light and switch to 12 - 12??? I also have foxfarm big bloom nutes. When should I introduce those?

Moved the smaller plants close to the light, topped one of the larger plants. Will have them close to the light till Thursday then switch them to 12-12
