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

Could be multiple problems. Is the problem getting worse or better? How many days was this plant in Veg and how long has it been in flower? Maybe you added the bloom nutes a little late.
