hi busybee, thanks for the reply, i started off with a basic soil for seedlings, and after 2 weeks under the light i repotted in to larger pots, and then used 35% batmix, 35% seedling mix and 30% perlite, its been a week since then and the last watering i watered with 1/5th of the biobizz grow stuff. I had to admit i think alot of my issues may be related to NPK diff but how long does it take and should i be adding more of the grow stuff?
