Yellow leaves and curled down. Update:Week6 flower

She's yellowing everywhere fast and still has several weeks to finish. Don't see any dead areas on the yellow leaves. Nitrogen deficiency looks like this but also leaves will look this way when the plant is feeding off of itself. Like Grower Tom said, check PH and TDS and determine possible lock out. Plants still need Nitrogen in flower

@John_Kramer sorry I’m just basing of what I see in pic 3, the others the color is hard to get real definition for me. What I see is drooping and that yellowing is uneven which is why I’m leaning away from senescence. I think the best advice anyone can give him is to check runoff obviously, high ppm or pH is out then need to lower salts. His other diaries he’s using synthetics.

@Grower_Tom if it'd be lockout then there'd be signs of Ca,Mg,K lock also i'd progress from top to bottom not other way Mo deficiency is also highly unlikely but not excluded K deficiency ? pfff xDD NOPE there is no signs

You don’t have a diary so I’ll go out on a limb and say you’re using liquid nutes and have salt build up and nutrient lockout. Judging by your other grows I don’t think you’d starve this one, that’s why I say lockout.

looks like n-deficiency and some senescence / fall colors. As far as the droop, either poor watering habits or maybe a pest chewing on roots? Something is off in rootzone, i'd assume.

That is a natural Autumn fading xDDD seriously now, this is clearly N,P starvation due to underfeeding i see a Co2 bag so u definately 'd've increase ur feeding

No diary, thats already a challenge to give right path. From look, its either cold temps ( natural fade or lack of molybdenum ( very possible )), plus lack of potassium and maybe ph drift ( from look of plant or leaf position ).
