Cannabis sativa from the looks of it 🤭. Plant looks fine. It's in flowering and using up nutrients. Be sure to water properly and give enough potassium and phosphorus.

Bottom leaves yellowing at beginning of flower
So my plants have been flowering for about a week now and the lower fan leaves are yellowing with brown spots. Should I be feeding them more of the flower girl I’m using or is this a deficiency of a specific nutrient? (following dr earth feeding schedule designed for cannabis)

Is she too far gone or can she come back?
Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

Struggling with deficiencies (nutrient lockout?)
Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.

Yellowing leaves and nutrient lockout. How do I fix this? This has been a long time problem. Definitely overfed for the first 3 weeks of flower.
Lemon Cherry Cookies locked out for weeks. She's yellowed up big time. Took in less than a quarter gallon water yesterday and a half gallon today. But then she had a higher EC and TDS before adding plain pHed water both days. After topping off it went back down. Check my diary.

Is this normal new leaf color growth?
It seems again that my leaves are a touch shiny, slightly curled down, and are a touch yellow. I water only 1 Liter every two days and do not use any fertilizer apart from coffee grounds and aquarium water which has slight minerals. Thanks for the help in advance
