Magnesium deficiency looks like. Check the ph and try some calmag

you need more potassium in your diet, my lady! adjust the ph at 6.5 before adding anything (any npk solution will be appreciated) happy harvest!

Calcium or other deficiency?
Is this a calcium deficiency? Brown speckles on only 1 leaf but some other leaves gave mildly upturned edges. I had what I think was a magnesium deficiency a week ago and added calmag.

Leave spot burn
I fed my 3 week autos yesterday a compost tea of living soil with molasses. And I noticed some spots. Maybe it was too soon? Light is too close? I’m not too concerned since it’s just one and the rest of the plant looks great to me.

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.
Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Friends! tell me from the photo what kind of problem is this!!!
I need help only with photos! without a diary! since I have already tried all the acceptable values of EC and pH, then the problem is something else!!! I think knowledgeable and experienced people will be able to identify the problem from the photo!!!

whats wrong with the leaves?
Im sure this is nothing to worry about but i just want to know what it is. Is it genetics or is it a deficiency that i can sort out. Im only feeding water at the moment. Also is there a name to refer to this condition? Because its not twisted or wilting?

Strange fan leaf markings
So I have some markings on the fan leads that I’ve never come across before. See the pics ... could this be bugs? Feed? Or a heat issue? Or is it simply mother nature , and the fact that we all have imperfections somewhere along the line?

Anybody know what’s going on with this girl? All in all, she’s growing right along with my other but some funky coloration and growth. Not sure if I should start a new one or let her go and see what happens. I appreciate any advice and input.

The ladies are telling me something but I'm no weed-whisperer yet so I'm gonna need help. They are now 3 weeks since germination and I've only been watering them once a day with a spray. No nutrients yet. I have a 3-2-5 nutrient for Herbs & Tomatos but maybe only while flowering?
