Mexican Airlines Auto - FastBuds

I saw some Thrips on the plant, i will be getting a pesticide for them, shouldn’t be causing a lot of problems other than a bit of “snail trail” and yellowing. I watered a gallon with the above nutrients. Water pH 6.5 Water runoff pH 6.3 I checked the ppm for the first time, water was 855 runoff was 1010, which means there is salt buildup around the roots, i will flush it next watering. Buds are growing well, no issues with growth other than the yellowing of the leaves.
