Lowlife question, help!!!

I saved 4 out of 8 Lowlife AK 47 x Hindu Kush seedlings, after algae in my systems killed the roots of 4 of them. I repotted in net pots with other seeedlings. They are looking okay. Here is my question: I have read other posts on here that have stated that the autoflowers don't need a change in photoperiod to trigger blooming stage, that they flower at a time of 3-4 weeks automatically. I have delayed the initial vegetative growth stage with the algae problem. Today is week 2 since germination. Will my plants make up for the lost time now that they are in an optimum environment. Or is it a waste of time, space and energy to try to get these plants to produce good buds?
Any one who has experience and would share with me, I will appreciate it!
