Magnesium, potassium, phosphorus, or pH?

I'm not too sure which one it is. I'm assuming it's all of them. 5th weeks in hydro. Sour Diesel. 300W LED (140 true w). 5 gallon bucket. Hydro with clay pebbles. I can't figure it out if it is magnesium problem due to the pictures and or potassium problem. There seems to be a lot of problems altogether. I can't figure it out. Can someone take a look and help me out?

If the ph is out of wack then it prevents the plant from taking up needed nutes. Which would make it look like an everything deficiency...you should monitor ph at least once a week. if your ph looks good then add stuff for vitamins and minerals

Yeah, I kept the pH at 6.2 for 2 weeks. I think that's why i was missing some vitamins and minerals. I just put it to 5.7-5.9 so it can absorb the other nutes that it wasn't able to. I hope that'll work, will try that out for 3 days to see if anything will change.
One question tho @pockitsPM , now that I had switched it to 5.8pH, would the old leaves that was affected die out and fall off or will it stay the same color until harvest?

if you feed them, they'll get darker, but the damage won't heal. that doesn't mean the leaves will immediately die or should be removed, only that the genie can't be put back in the bottle.

need to know some details to give any real input and/or advice... also need to see pictures in natural or warm lighting (ambient sunlight or regular bedroom light). the coloration of the leds make it nearly impossible to be absolutely certain of damage, as it alters the image and natural coloration of the plant material.

what are you feeding? when/how often? what ppm?

what are your water temps?

what is your lighting schedule?

5 weeks from sprout or root (if cuttings)?

what is your humidity and what are your day/night high/low temps?

what kind of 'hydro 5g bucket with clay pebbles'? ie (dwc, top feed, recirc, ebb and flow, hempy, etc)

it's not damaged to the point of 'oh fuck' by any means, please provide details and i or others will provide you with more detailed answers.

good luck @Onetimeonly !
