Looks like overfeeding/nutrient burn. I'd suspect potassium toxicity due the the yellow/burning tips. Thin new growth and ur large bloom feeding u just did. Dial it back fam. In most cases with cannabis less is more. Happy growing and stay lit fam.

The leafs started to look yellow in the middle when I checked on them today. They looked fine to me yesterday so I guess this happened in the past 24-48 hours, not sure why. It can be seen on Day 12 pictures. Is this normal or I should be worried?

Lowers getting blotchy yellow minor rusty spots? 4th week of flower...P/K issues?
What's making these lowers blotchy yellow with some 'rust' spots? Any ideas? I think it's probably a P/K issue, am I underfeeding? Blumat drip system, Promix HP, Maxibloom @3.5g per gal. Ca/Mg @ 5ml per gallon. pH @5.8-6.2.

Burnt tip deficiency?
On every grow I see this same deficiency, it doesn’t appear on new growth. It normally appears on older leaves sometimes from the node right before the new one and lower on the plant. I’ve feed cal mag 5ml all the way through. I was thinking it might be sulfur but not sure.

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Overwatered - Should i start over?
Heavily overwatered about a week ago. They never really recovered. I fed them some cal mag a few days ago and they perked up a little. Poor aeration in the soil. Last picture is a comparison with my 3 week old blue dream/gorilla cookies. Should i just throw these away and restart

Light yellowing leaves
Some light yellowing on the leaves, more on the smaller nodes towards the middle. Could this be related to my accidental topping, or possibly due to uneven watering? It was very bushy when i tried to water it last, so i am not sure how evenly the soil was saturated.

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

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?

Yellowing fan leaves
Larger, older fan leaves turning yellow slowly. Rest of plant still doing great. Also, leaves are reaching for the light. Is this due to maturity? Or might something else be going on?
