The one looks like nitrogen deficiency and I'm not sure about the other. Without more details it's hard to help. What's your pH? What nutrients are you using? What strength are you feeding at? These are all things we need to know to help you better.

Your ph looks high to me, for my grows I try to keep it around 6.0 Not sure how old your plants and I'm not familiar with the Rhizotonic, but with the spots I would think your PH being high is blocking nutrients. From the pictures you may also want to up your CalMag a bit, but it could be PH blocking it, so address PH first.
Nice Looking grow!

hi tgo,
i'd agree with the above, N deficiency and somewhat with pH.
pH can be between 5.5 - 6.5 , and nutrient uptake varies across that range.
N is fairly universal across that range - if theres not enough, you see N deficiency.
the spots, i think, are more calcium related - early sign of calcium deficiency.
if i'm not mistaken, the spots are only on the parts of the leaves that get light...
those parts in the shade of other leaves seem unaffected.
if the GH calmag has N in it, (1-0-0) all you'd have to do is add a bit more calmag...
i'd suggest to up your base nutrient with N with 25%.
Calcium is best absorbed at pH 6.1 up.

To me everything looks good except the MaxiGro. The Rhizotonic looks like something similar to Hydroguard, and I use CaliMagic as well. The MaxiGro however, is a one part solution so you can't really adjust NPK ratios individually, they all raise and lower equally. With a 2 or 3 part system you can adjust individually if needed. For example, something with a grow bottle and bloom bottle, and if it's 3 part it usually has a middle one. I use GH Flora trio at half strength-ish personally and it works great. Been playing with the levels on mine a bit, you may try the same. As was also mentioned, the CaliMagic is a 1-0-0 ratio, you may just try upping that a little first. I'm definitely not a pro or anything but my ladies seem to like what I'm doing this time around so I'm sticking with it. I've also used the Flora duo with good success.

Does anyone have a clue about this??
Is it nuts burnout? It’s the only plant with that deficiency.
im using Calimagic, Max Gro and Rhizotonic.
ph: 5,8 - ppm: 1000 - Rh: 50%, c: 22 - temperature of water: 20.0.
