everything was going great I'm growing in a mix of fox farms ocean forest, steer manure peat moss and perlite. I been using fox farms grow and big bloom. It started on my medusa strain with dark brown spots and a dark stem. I self diagnosed as a phosphorus deficiency and I added raw phosphorus my npk some of the infected leaves dried out and died, now I am seeing what up see in these pics. I'm not sure if it is the same thing as I do not see the purple stalk. we had a heat spell last weak so I'm not sure if this helped create the problem. also I try not to over water but I may have the last couple weeks as it has been hot in cali.
