Yellow and dead curled leaves, 6 week into flower

Im sure you get this question all the time, but am wondering if someone could take a look at the attach pictures. I have two lemon haze with good looking buds but, leaves are dying all the way up to main cola. Its in some fox farm dirt, 5 gallon buckets. I water once every 4 days or so (depending if its dry 1 inch down). Using some foxfarm big bud nute's once a week. These 3 are sitting under 1 , 1000watt HPS. We have an AC set to 67 (room itself stays around 75-79f. Reading up the one with the real yellow leaves looks like a nit deficiency. but the lemon haze leaves are curled and just dropping like flies. Could anyone take a look and tell me what they think?

Been doing this for a few years now and the past 3 batch's all have done this to me. Could it be root bound, root rot? Thank you for any help guys! Let me know if you need more info.



This one is lemon haze, notice the crispy leaves

I've lost too many plants with similar symptoms. They might be too big for 5 gallons. Another grower told me to keep them under 2', 3' max.

Seems like mostly N deficiency. Nitrogen requirements taper down during flower but the plant definitely still needs healthy amounts. What's the NPK of your nutrient mix and how much do you use? Btw I recommend a ppm meter even even for soil. It makes gauging you nutrient schedule so much easier and also helps to keep your strength of your feed consistent even if you have to change brands

remember too guys, that nutritional requirements are higher the bigger a plant becomes. Every haze I've grown typically stretches a fair amount and become huge during flower. Next run maybe feed with every watering and see how that works for you

Thanks for the responses. So its possible a combo with 5 gallon bucket not being enough and then a N deficiency on top of that. I can't tell you the NPK just yet because i'm not there atm. I was always afraid to give them too much Nutes but I guess when they are that large, they really do need more help.

The small girls I made before flowering i'm putting in a 7 or 10 gallon Breathable Fabric Planting Containers and pay more attention to the nutes i'm giving them. Now the PPM meter, do those have the metal spikes in them that stay in the soil? I will have to get one of those.

Thanks for the replys!

any other thoughts?

how close are the lights? are they on 1k? light bleaching maybe? did u water them enough?

That's not what light bleaching looks like and trust me, a five gallon pot is more than adequate for an indoor plant. I honestly believe that they just aren't getting enough nutrition so they are pulling it from the leaves. Next run either up your dosage or feed with every water.

have 2 mothers that are suddenly going to shit like OP's.
