hello all, this is my first post. Second grow, and I'm in dire need of help. My girl is 7 weeks old and fan leaves started yellowing and developing huge rust spots at about week 4 and theyre slowly dying off. I know lower fan leaves are supposed to die off naturally (depending on the strain)_ but it seems to be climbing up plant. This is an all organic grow, started out in fox farm light warrior until 3 weeks old. Then transferred to a 50/50 mix of light warrior and ocean forest. Ive only supplemented with big bloom once so it cant be nute burn. Im sure its a deficiency, maybe calcium/magnesium ? Shes 18 inches tall and my temps are at a steady 76-79 degrees wiith humidity at 40% while the 400 watt metal halide is on. Im using distilled water, ph at 6.5 every watering, ppms are at about 200 at this point. Any help on this matter would be greatly appreciated.
