Pin pointing deficiences - Good pics included

I have two plants going, they're around 2 and a half months old now.
-Plant A is an indica dom, unknown strain.
-Plant B is sat. dom, tangerine dream.
-they're in 5 gallon smart pots with 70% fox farms ocean forest/30% verm.
-they're under a 400 watt hps and a 215 watt t5 4' 4tube.
-their source water is city tap. water is let to stand for 24 hours of dechlorinate. water comes out of tap at 7.4ph and it's adjusted to 6.8-7.0ph with ph down.
-feeding is done with a organic tea mix. i make my recipe into 1 gallon so it's 2x strong then I cut 1 part with 1 part water before feeding. recipe is: 2 tbls. sunleaves mexican bat guano, 2 caps of maxicrop liquid seakelp, 2 tbls. organic blackstrap unsulphured molasses into 1 gallon of the ph'd source water. it's then aereated with aquarium pump for duration.
-feeding schedule is: water until a little runoff, let dry a few days until pots are noticely lighter, feed until little run off, let dry a few days until light pots, water repeat. the indica Plant A drinks and feeds almost twice as fast as Plant B.
They started out in life rough, damping off almost killed them as seedlings. They've stunted a few times due to either lockout or lack of nutes, also had to deal with them both "clawing" due to watering issues. they took right off once I transplanted them into the FFOF though, they cruised in the FF for probably a month until I started feeding them. 2-3 weeks a go I saw a few little changes in the leaves.

As for the deficiences I've noticed. Plant A I know has a nitrogen def judging by the older bottom leaves turning a consistent yellow which I'm treating by feeding it N more often. It's showing I think two other problems as well... Some leaves on plant A are experiencing bleach blotches running along the middle vein, I have no idea what this one could be yet. Also, there's a few leaves that have dark blotches as well, my reading is leading me to think the dark blotches might be lack of phosphorus? It's already not getting enough N so this makes sense to me but I'd like expert opinion.
My sat. dom Plant B is showing different issues I think. I'm seeing on a few leaves bleach blotches, again, not sure what this may be yet, possible nute burn site?
The main issue for Plant B is leaves turning not entirely yellow with dead brown spots and tips turning inward, there's also several leaves with yellowing tips which haven't progressed yet. From my reading on this one, it could be several things. Calcium, Magnesium, Manganese deficiences all sound like this. I have both epsom salt and lil miller super sweet limestone. I was planning on trying an epsom salt foliar spray to start checking things off the list but I figured it'd be wise to get any leads to narrow things down first.
I've tried to include everything but if i missed anything, just let me know.
Thanks for any help guys!

Picture 3 is phosphorous deficiency picture 5 is heat stress/ light burn. I got the easy ones but the rest could be manganese but ill let the experts give their input

thanks for the input wubstepp and hotrodharley.
That reminds me, I forgot to mention the 400watt is being kept 15 inches from the canopy.
And also, about that vegetative tea recipe I have listed in my previous post.. I forgot to mention I was adding 1 tbls of sunleaves jamacain bat guano for a phosphorous bump.

hotrodharley, those deficiences you see are for Plant B?

On hand, I have the lil miller super sweet for calcium, and maxicrop liquid seakelp for potassium. I'm brewing my flowering recipe right now of: 1 gallon source water 6.8ph, 6 tbls. sunleaves jamacian bat guano, 2 caps liquid seakelp, 2 tbls. molasses. I'll be cutting this 1 part water/ 1 part tea for a full strength feed.

- For the K and calcium fix - would it be best to make seperate foliar sprays, one calcium, one potassium, or one foliar with them combined?
- For the P fix - would my flowering tea be the ideal fix for that, or maybe just topdress some dry jamac. bat guano?
- The tea will also have a good amount of K, so maybe just need tea in a day or two for the P and K, then limestop foliar for the calcium?

They're going to be put into bud in about a week, if Plant B has got a phosphorous problem, it would probably be best to wait on taking clones from it do you think? Root growth for the clones might not be too hot if mom doesn't have much present right?

Drop pH to 6.5 . No clones until healthy generally unless a save effort. Top dress soil with the lime...say 1 Tbsp each to start. work into the soil with a fork or something. I'd feed with watering vs foliar.

add lime, mix with fork then water that's ph'd to 6.5. thanks for the info coho, i'll be doing that tonight and i'll post results

the plants seem to be stable, the night I added the lime I removed all the problem leaves to see if any new ones start to turn. If they are indeed stable, should I add in another tablespoon of lime to give it extended stability. I dont want to have to wait for this to start to turn again before figuring out I only added enough lime to give them peace for a few weeks.

wanted to to update, plant B still has leaves turning spotty brown. few new ones that are green but the the ends of leaves are getting the rust spots. is another tablespoon of lime recommended as the fix?

nadda huh. well thanks for the help up til this point, i guess i'm going to have to figure this one out on my own even if it kills my plants.

I see you added the lime, but did u address the P def? It looks pretty large.
U can of course add a flowering tea, but of course, this raises the question if your veg feed contains the required nutes.

you're saying the P def. looks major?

flower tea is as follows: 6 tablespoons sunleaves jamacian bat guano, 2 caps of maxicrop liquid seakelp, 2 tablespoons of molasses - aereated with aquarium bubbler. this mix is cut 1:1 ratio with water to make a full strength tea. Veg tea recipe is the same only difference being i'm using 3-4 tablespoons of sunleaves mexican bat guano for the N source, and only 1-2 tablespoons of jam. bat guano for a P boost.
been rotating a veg feed, then water, then flower feed to try to meet all the demands right now ever since I started seeing the brown spots. up until this point, i was feeding strictly a veg. tea, then pure water next water, repeat.
I added that first tablespoon of lime and watered as directed, looked good for a day or two since no new leaves were turning. then i noticed leaves that were previously green, are now turning. so i added that second tablespoon of lime last night. question is... how many tablespoons should i not exceed while dialing this strain in?
also, should i be considering adding any epsom salt to the mix to give a better magnesium source or does anyone see a need?
thanks for the continued help, there's still hope in getting these girls back in shape.
