Is it on new or older Leaves and do you have perlite in soil?

That's why I said to water only for a bit. When you fed and didn't get good run off it caused salt build. Had you not watered with water only to good run off those spots would have been worse.My plant did stall for 3 days, but fkkkk what's happening!! Out of 2 plants, only one has the yellow spots
You running tap water? If running distilled or r/o water you need to add a bit of cal/mag every time. Those two waters are void of minerals and will rob them from the soil.
Carry on with water only a couple more times then start back to feeding with good run off. A bit of cal/mag wont hurt.

Yea I would let it ride for a bit like kids they will grow out of it lol
i didnt get to fully read all the posts above, but i dont think that is calcium deficiency.... calcium deficiency is more pattern like...
i do think its boron deficiency because of the current location at the tips, and the age of your plant. the growing tips will eventually start to die , and youll see dead spot scattered across the leaves (dead spots wouldnt be large)
remedy... better irrigation practices. boric accid is the easiest step, but making use of compost, compost teas, or borax will get the levels back to normal...

Just to add my 2 cents...if you just started feeding them, I assume in week 3?, then I would doubt its a salt build up. It does look like the start of a cal deficiency, and while it's early for it, you have to make sure its not a lockout issue before adding more to your medium. You say your water's ph is 6? Try to test your soil as well because at ph 6 your running on the lower limit of calcium uptake. Try to raise the ph to about 6.4 for a few waterings. The awkward yellowing is something else though. To me, it can be the leaf getting stuck to another one due to moisture and if it stays stuck for too long, it can yellow like that. Splashing ferrted water on it can do it as well. Becareful with that cal deficiency though, because as you start losing calcium, your soil will also become more acidic as a result, and watering with ph 6 and soil getting more acidic, your opening yourself to other lockouts/deficiencies in no time! Im going through the same thing in week 7 of flower though..started a week and a half ago and it began with calcium, finally got it under control, I think lol 
I actually used some organic coconut water with higher amount of calium and magnesium and it had a bit of iron.

Thanks for the input man! I got crushed eggs in vinegar waiting to stabilize while I'm basically flushing my plant... I don't have fast access to cal-mag therefore I made my own fertilizer (crushed egg shells with vinegar) while I'm waiting for result from my run off results...Just to add my 2 cents...if you just started feeding them, I assume in week 3?, then I would doubt its a salt build up.

I did that on my first grow as a foliar feed, I also added dried crushed up banana peels for the potassium mainly. Even though those two plants didn't exhibit a cal deficiency. I don't have cal mag either, I used Epsom salts for the mag and coconut water, either organic or fresh from a coconut. I will get cal mag as Epsom salt is not a great idea in the long run if you use it for watering, it is a salt afterall..it is good for foliar feed in veg though.Thanks for the input man!

Looks good to me the lower leaves will not heal but tops leaves look good that's all that matters it is not spreading
