You do not have a diary so we are guessing based on one photo. It could be a magnesium deficiency.

Natural or Problem?
Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

The clone has bad leaves. Need help
Tell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Leaves have developed "claws" at the tips that bend downwards
My leaves have developed "claws" at the tips that bend downwards. I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate) Now my question to the professionals: what can I do to fix the problem? Green greetings! 👽

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Yellow leaf tips
Hello, I think I have a slight over-fertilisation. Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.
