Spider mites on seedlings in solo cups. When to transfer?

I just like pics of weed, especially soon to be sexy weed plants like these babbers

I used that GoLine to one time

How'd you find it Stevie?? I used it the very first time I grew years ago...it came with my tent, I'm still in the process of mastering nutes, so I doubt I could tell ya if it worked well or not.

It worked okay for me but I'm growing in Coco so I don't know if maybe I just needed to do some more adjustments to receive some benefits from it but I think if you were growing in soil it would be a good line to use
