  1. My plants are on the 23rd day today...1 is about 10 inches and the other 2 are about 8 inches...all are very bushy...

    when can i ad my 20-20-20 ferts?
    when and how much epson salts do i use?
    when should i send my plants into flowering?

    they are in 4 gallon pales and the strain is northernlights#5-blueberry.

  2. hmmm, I'd wait about 5 more days till you fert. I'd use 10-10-10, but 20-20-20 would work...just a bit powerful, be careful how much you add.

    As for when to flower, its up to you. Keep in mind it grow double the size during flowering, so start whenever its half the size you want it to be after flowering.
