Ethos Cherry Gar-See-ya R1

That's some very tall growth patterns on that plants main cola. I think you may need to keep your light closer next grow. Or get a higher output grow light. Its looking like some potassium deficiencies. Maybe the soils PH is off or the salts have build up so much its causing a lockout. The feeding schedule suggests that Big Bloom is to be combined with Grow Big and Tiger bloom. I'm not seeing any grow big in your feeding plan? https://foxfarm.com/download/13115/ This is their soil feeding guideline. It looks quite hot though I'd maybe cut this back by 1/2. Best Of Luck!
