Auto flower preflower

Hey so I'm new to growing auto flowers and wondering How long and what to expect from preflower stage.

I have 2 plants , which showed stigmas about a week ago , the plants look healthly and have been growing rapidly up until this stage but things seems to have stopped. No new pistols or any flowers forming.

What should be happening at this stage and what could be going wrong?

What strain is it and how many days since they popped? They look fine and most likely are just entering the stretch phase of flower when they should be going nuts in growth. Pistil development and budset would come a little later as in a week or two, strain dependent.

They are transitioning to flower, give them time.

Hey thanks For the input, 1 is a formula 1 auto and the other white widow, they Are 33 days from seed. They Had explosive growth in veg but things seemed to have slowed down. How long does the stretch last and is it after the stretch they start to bud?

Stretch is the first two weeks usually of flower and it's when they start getting pistils but as far as defined buds it might be at the end of that period before you'll call the clusters of white hairs buds. Then the growth upward of the plant will slow and eventually stop and all the energy goes into pumping up the flowers for the remainder of time until harvest. Giving the plants enough nitrogen during this time and not prematurely switching to bloom nutes only is important in my opinion as they are going to go through a big growth spurt and can use some extra N. I like to mix bloom and grow 50/50 during the transition but I use organic dry amendments. You can also do it with salt nutes but maybe some people that use them can chime in with what they do as far as that goes.

That's What I've been doing, as soon as I seen preflowers I switched to 1ml grow and bloom.
