nope its not overfert your low magnesium.
Magnesium (Mg)
Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.
Magnesium (Mg) deficiency:
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.

Hmm ur ph seems right, let it cycle between 5.8 and 6.3 instead of keeping all the time at 5.8-5.9

How much nutes did you use?

I would have to agree that it is some kind of def, progably a cal/mg def plus some form of npk def (red stems might mean P def rather than genetics)

1- Before the browning around the edges occurred, did you notice that the edges were becoming light green while the middle of the leaf was darker green? If so, typical mg def

2- Your stem color (redish) tells me you are def, prob in phos

3- Like said previously, ur running a light green color, so how could it be an N nute burn? they would have to be dark even purplish green for an N burn

4- U can try foliar feeding with a very light dose and see how she reacts.

But again, how much nutes did u use

And you might also be running the light a bit too close, I see some curling up on some of the pics. What's us humidity like?

I would say you need nutes for sure then and most likely a micro-supplement with mag and cal do you use R/O water or filtered water if you do then you most likely need mag and cal, zinc, ect.... when was the last time you changed your rez?
