Hey there so i will agree that the plant on the left does seem a bit minimal with leaf count, and i see your burnt tips, i also noticed a few leaves that seem somewhat curled. If they got picky with nutes and had a small freak out it may be that this is what you have to work with, if you could not have any more damage to the remaining leaves that would be good...sometimes easier said than done though. But also you're only 6 weeks into flowering and this strain has a 9-10 frame...which in my opinion probably means more like 11-12 especially since its a haze and they typically have a longer flowering time. Id say keep her nutes low for a bit, watch out for wind burn if your fans are going, and watch your reservoir and roots closely. It may be just a matter of being patient and letting the flowering progress slowly. Happy growing, I hope things smooth out.✌️
