Your nutrient levels are very low for week 5/6, you would do well to increase this to 2 or 3ml per litre, Your light is perhaps either too close or too far away. Grab yourself some calmag and add it to your feed at 2ml per litre, makes a massive difference 🌱👍

She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Is this more nutrient deficiency?I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?
