per NebulaHaze " Extra Growing Tips for Autos

Low to Medium Nutrient Needs


Whether you grow in soil, coco coir, or a full hydroponic setup, auto plants often tend to prefer relatively low levels of nutrients compared to many other cannabis strains.

When it comes to adding extra bottled nutrients, start at 1/2 strength of the recommended dose or less, and only add higher levels of nutrients if needed. In hydro use “vegetative” nutrients until you see “budlets” (little bunches of white hairs) which is often around 4-5 weeks. In good soil, you don’t need to add any nutrients during the vegetative stage. After the first signs of buds, start adding “flowering” nutrients at very low strength (1/2 strength to start)."

thank mate,, so what do you think ok the photos uploaded? dose it look like nutrient burn?

maybe a leetle bit. I don't think you really need anymore nutrients until you start to bloom.
