Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves.
Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

First grow, calcium deficiency?First grow, help please.
As seen on the pictures provided, the leaves are getting brown spots on them with some kind of yellowing. I also do have some yellowing tips. I do suspect a calcium def. after some reading but would highly appreciate the input of a more experienced grower

Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Possible Nitrogen Deficiency?Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

Papaya - looks thirsty and starts yellowing on lower half :'-(My very well trained photo Papaya (Nirvana - Citric x Ice) is significantly decreasing in happiness since yesterday. She looks thirsty but the fabric pot is still heavy and moist (watered 4 days ago), also the leaves on lower half turned yellow today. Too much / little of what?

When to start using Cal Mag?Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc.
I believe this may be nutrient burn?
Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Help validating what this isMy plant seems to have developed some kind of deficiency/excess. I researched and think that it's CalMag deficiency, added CalMag to my nutes (1ml/l). Just wanted to check in with the experts here to get a second opinion. The growth seems slow I'm afraid I may have stunted her 🤦

What deficiency is this?What's my plant missing? Growth has slowed down, and I think I'm seeing veinal chlorosis, see last picture in week 2 / or attached pic.
I've been feeding A + B with a tiny bit of cal+mag at an EC of 0.8, now reduced to 0.6, pH around 6.

Yellow new foliageFrom my research it could be phosphorus toxicity, iron deficiency or sulfur deficiency.
Or it could be over watering.
Or it could be poor drainage.
Or it could be light deficiency (I have a 42watt Tled with some led strips until Mars 600 arrives)
