Phosphorous and potassium deficiency. A P/K booster will fix this. The damaged leaves will not recover, but it will prevent this from getting any worse. Both these nutrients are needed in larger quantities during flowering.

PLEASE HELP! See former question as well.
Continue to see deficency or burn in leaves. I have fed her only ph water for 2 weeks and it continues. I asked for help before, everyone just tells me what they think is wrong and not the reasons why. If you have an answer it would be appreciated to know your reasoning. Thanks🤘

Lime green leafs
I noticed the top leaves are turning more lime (see pictures of day 74). I used the same nute ratio for weeks. Should i do something, or is it simply the plant reaching the end of its life?

Delaying Senesence?
Delay Senescence in cannabis while employing a staggered harvest? Is this possible? I'm thinking about cherry picking my top colas as they are milky and starting to turn to amber. There are also new bud sites that I wish to feed and maximize yield.

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.
Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?

Lower two sets of fan leaves have gone yellow, leaves on internodes in between haven't changed colour. Not sure what's causing this. Nutes? (3-4 more weeks of time released nutes in soil) Too much water? Did water a bit extra because I wasn't going to be home for a couple of days

Deficiencies? Brown spots, yellowing and purple stems
What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.
