I know the problem... I have brought them to my friend for babysitting (in the winter -30 C), well wrapped but there, they had CFL's instead of HPS... And all this stunted the growth for few weeks and here the bastards hit!
Super Thrive is a ER IV for plants. It's good shit, but I'm scared of it. 1/8th solution. Baby Sitters will never take care of the kids like the Parents.
