Wtf am i dealing with?? Pest or deficiency?

Im new to the Hydroponics scene, this is my first hydro grow, im about 4 weeks into veg with this grape diamond and it started showing some issues about a week ago.
Everything's startes from the bottom and moved up. Also first signs started appearing 2 days after feed. Not sure if its pests, nute excess or deficiency?? There are orange spots on leaves with clawing starting from the bottom. A few black spots on top leaves not sure if they are turning brown or orange. Ive asked my friends that grow too they have no idea what's wrong with my plant either.

Any pic

Here are pics

I found a post with some answers:

Does not look like a pest... something going on with your feed or medium...

Thanks bro i been checking the ph alot more and it's been going up. I changed the water yesterday and made sure ph is always in check and roots are loving it alot of new growth. Will post an update tomorrow on it to see if it gets better or worse.

Specifically, it looks like PH is causing a cal-mag deficiency, which gets blocked out more dramatically the lower the PH goes.

Troll smarter, not harder.

My post is clear and precise, if you have questions about how PH works, use google. But, going by your previous posts of your garden, pretty sure you know what the hell it is.

As a master of 3 decades of growing you should know there is no such this as a calmag deficiency. C’mon man

Hey, welcome to the forums. A few long running jokes to get you started:

If anyone asks how much longer their plant needs and how much it will yield, the answer is always "2 weeks, about a pound"
If someone asks about flushing, we tell them "flushing is for toilets"
If someone asks about a deficiency you will always find someone saying the problem is "cal mag def"
