Leaves curling and fading in week 3 flower

[MacAttack]

Hey all, this is my second grow and I’m running into a bit of an issue it appears. Veg went really well however these last 2 weeks I’ve been noticing a slight curling and discolouration of some leaves and tips yellowing.

Any tips would be appreciated!

I’m currently watering every 2 days - feeding every other water (so once a week roughly) with green rush following the dosage on the bottle (1 scoop/tsp per 1gal of water) however admittedly I’ve might’ve let them go 3 days before a water once or twice since beginning flower.

They’re sitting in 1gal pots (I’m doing full grow in the 1gal pots) under a SF2000 at roughly 14-16” from the TOPS. Tent temps seem to be hovering around 22-24C & 50-60 humidity.

Cut back on the fertilizer, and only water when the soil dries back.

I recommend never following the the fertilizer recommendations on the bottle.. Try half strength to start.. Seedlings I give about 1/20 strength to start from first sight of real leaves.. In coco I never feed full strength.
