Having some issues with my AutoFlower GG4 strain . The leaves looks to as if they are rusting and she is 50 days old as of today . Thought it could be a cal-deficiency or even nutrients burn , I have tried to flush with still the same results . If anyone could help anything helps thanks .

What are you feeding them and how much? Also, what are the temps and humidity like with lights on? When you say you did a flush, did you use just water or a weak nutrient mix? Those answers will help you get better responses.

Nutrition I’m running the fox farms trio. -Big bloom 4:1 Tiger Bloom 3:1. Teaspoons to Gallon Ph : 6.5

Temp- stays on the low end around 73 high end 80
Humidity - 55-60% Flushing meaning ( Fox Farms Sledgehammer 0.5/1
Seen no change so done another flush with straight water ph 6.5

Sounds like the temps and humidity are good. When you're flushing to do a reset of the ph or ec in the media it's a good idea to use a mild nute solution so you don't strip all the nutes out of the soil and leave the plant deficient. I'm not very familiar with the fox farm trio to be honest so I can't say if that's overfeeding. However most auto flower strains do best with lower feeds than photos I've found.
