Nitrogen Toxicity or Deficiency?

Hello all and happy growing!
I have two plants and two different strains.

Gelato - seems to me a little bit dark green. Not sure if it could be genetics or not. Has some purple stems on the fan leafs. Can it be a toxicity? I don’t see the falcons talon where the tips curl downward so I assume it’s not a Nitrogen problem. Obviously I can be way off.

Skywalker OG - Next to the gelato plant it looks super light green. Lower leafs are yellow from previous deficiency. But can this deficiency be ongoing since I see some fading between leaf veins and discoloration overall.

what do you guys think?

In my opinion the Gelato is looking great and the SkyOG's deficient in N probably since it always starts from bottom leaves. Medium? Nutes?

It’s what I was thinking (or possible MG def also) because of the leaf colors as well as picture #4 you can see the lack of color in between leaf veins. I have them in FFOF and watering them one on one off using FF dirty dozen. Last water was 5 days ago straight PH’d water.

I really don't see the MG def. Maybe it's the lighting. I see slightly lighter colour between the veins of the leaves on the left in the 4th picture but it's very subtle. I had a battle with MG def in the past and it looked way worse. I haven't used FFOF so can't really help you further. I know it's a hot medium and people usually overfeed but it truly looks like N def. Wait for more experienced replies and good luck bro!

Just realized you are using FFOF ,,,,, simple feed bump by way of Top dress More GFOF and water in at PH 6.5 . I run FFOF in my layered mixes. This will recharge medium if plant needs more from the soil.

Also ... let soil medium do the main feed ... alone.
Dont start dumping this or that on FFOF , it is already nute charged. Some strains look like this as they acclimate to it sometimes but it will grow out of it.

The plant in the picture is magnesium deficient.

The picture posted by Eugenios or OP? I was thinking on giving Cal-Mag foliar feeding twice a day to see if fixes the problem. But I am also afraid to be off and hurting it. I guess one true way to really find out.
 
I Just repotted these so I was thinking on letting them feed off the FFOF soil alone since I know it’s good for some time. When is it usually time to begin feeding additional nutes?
