I have 2 beautiful girls who have had a minor over fert. problem from scratch. I used MG time release fert. soil and even added a cup of Osmocote time release nutes to the mix, with perlite. I,ve had very slightly burnt leaf tips and the claw from the beginning. I,m wondering if I can give them a long flush before entering the final phase of flowering and clear their systems of nutes. I,d also like to add my MG 7-50-7 at least once before the final 2 weeks, but with the time release nitrogen already in the soil, I can't. Would a long flush clear out all the time release nutes?
