Cal/mag , nitrogen deficiency, or over watering?

Hello all, this is my first post here, really interested in any feedback I can get!
I have A girlscout cookie clone that was cruising through veg stage for the first 3 weeks of life, in FFOF 5 gallon and with ph'd water around 6.5-6.8. After about 3 weeks i noticed that the lower older growth was begining to wilt and curl a little bit. I trimmed the dead leaves then thought nothing of it after that. Recently however, it seems that the wilting is moving up the plant. The lower leaves started to claw and droop, but the upper plant still looked dark green and healthy. However, about 2 days ago, I noticed something that appeared to me to be a cal/ mag deficiency at the top of the plant. The new growth (meristems) has also changed color to light green/ yellow. I just watered this plant yesterday with about 1.5 L's of water...
So pretty much my question is can I try to water again today, with new nutrients including a 20% cal and 2% mag powder from aurora organics? Or do you believe these are over all symptoms of overwatering? I have been watering every 3 days, however the top leaves dont claw. Its only the lower ones, which makes me assume it isnt overwatering that is causing the lower fan leaves to claw...?
Additionally, I have heard that clawing is also a symptom of nitrogen toxicity, however once again the tops of the plants dont seem to experience the same symptoms as the bottom. Finally, I have heard that meristem yellowing can be a symptom of nitrogen defiency as well... Many hours spent trying to figure this out.
Here are the pictures, the first one is the top of the plant and the second is of one of the bottom of the plant.
Would be grateful to hear some opinions!

it doesn't look that bad.. new leaves can start out yellow, not an issue....a little bit of clawing ain't the end of the world, relax and smoke a joint

That's probably a nutrient problem. Those cupping/wilting leaves are signs for nitrogen toxicity. Your leaves almost look bluish! Nitrogen is first stored in lower leaves and then is transferred to new growth when needed. That's why older leaves always become affected first. Too much nitrogen can also lock out other nutrients, like calcium. So stop feeding N!

It looks like your feeding it just a bit to much nitrogen (leaves curling in and down). The yellowing tops is just normal growth. No need to flush just water when needed for 2-3 weeks and the plant should recover on its own. It doesn't look that bad, but your right on the edge of nute burn.

yes, thank you for the quick response! I do agree that the top fan leaves are turning almost blue. Are these symptoms of n toxicity as well? or was i right in believing it is cal mag? Additionally, I have another girl scout in with the same conditions,( 5 gallon FFOF) with none of these symptoms. The meristems on this plant are bright green and healthy, not as yellow,

Dude, GSC can be very finicky in veg sometimes and I've seen many growers having weird problems with it. With this class of strains, a small problem can give birth to some larger issues.
Dark green/blue leaves are symptoms of nitrogen toxicity.

This is the best way i can describe the problem, except with more curling. I also just realized that I added a new layer of soil on top to fill out the rest of the pot, im wondering now if that could cause ph or nutrient issues. anyway here is my comparison:

all new growth continues to get lighter green/ yellow and pale with skinny wave shaped leaves? please help? I cant imagine its a nitrogen toxicity.... its been about 4 weeks and from what ive read, FFOF runs out of nutrients around then and i havent added nutes until today... I watered again today with ph'd tap water at like 6.5 and foliar fed with a tiny bit of cal/ mag and age old Grow. I havent checked runoff yet, but i will the next watering... Do you think it is a PH problem/ nutrient lockout of some sort?

Yes it is. And thats a general window..it looks like n tox..a little and newer leaves can be rounded but the serrated edges will usually "wing out" with growth.

I had something similar my new growth looks like yours also and it turned out to be Nitrogen Toxicity caused by HOT soil and a little fert feed, I thought cal/mg so sprayed her and it made things worse as it upped the N she was getting.
