4x2 tent, organic grow FFOF, dr earth fertilizer, 3 gal fabric pot, es300 light, 2nd week flower, temp 77 and 70 lights out, humidity 50%, 2nd grow ever. Thinking it magnesium deficiency but not sure. Found on net that adding epson salt (1 tbsp) to water would help for organic grow. Tried for 2 waterings leaves appear light green and more spots forming.
Any ideas tips or suggestions would be gr8ful. Thx
