I actually started this seed the same day as my Purple Punch Cookies (PPC) grow, but the seed head was stuck on this one. I removed the head immediately, but the membrane was still attached to the seedling and it took me a few hours of research to get up the nerve to remove it, and it's been about a week behind the PPC development-wise. :( Lesson learned for next time.
Started of nutes at ¼ strength during seedling stage and worked up to ½ strength.
