Is This Calcium Deficiency?

Title pretty much sums it up here's pictures to go with it, i had it down to calcium or manganese deficiency then i was looking through my nutes and i seen that there's no calcium in any of my nutes there was plenty of manganese in them plus other trace elements but no calcium. but i still don't know for sure if it is calcium deficiency never had this problem before so need some opinions.

I don't think so...are you using tap water? From a well or city water? because if you are you ar unlikely to see a calcium deficiency unless you create one yourself by adding too much nitrogen.

yes that is calcium deficiency. some plants under leds are more sensative to calcium. i have one that the leaves closest get cal deficiency bad for some reason havent figured it out competely yet. but i would add some cal/mag to your water. if you are using r/o water it is a must.

ive had that same problem as a calcium proficiency before to. if you havent flushed your medium in a while try that let it dry for 48hours then get back on schedule with feed. be sure to use clean water to flush i use distilled. but ive cured that problem by using this method.

what kind of cal/mag to you use? ive herd that the magnesium can build up and then block out the calcium.

i use the city's tap water from my sink, it might have been to much nitrogen but the nutes i'm using barley have nitrogen. also i don't check my ph but i haven't had this problem before with my other grows same nute same water just different genetics.

yeah...I don't see anything on those leaves I would even worry about if they were my plants...
If you aren't using distilled or reverse osmosis water than your plants are getting calcium already in the water you give them...which is why it is left out of most nutes...I don't use LEDs so if they somehow cause a calcium deficiency then alright...
but I would say try some cal mag, bit if everything gets worse after you use it then you will see what a calcium and magnesium deficiency looks like...sometimes overages cause deficiencies...it's strange the way everything works together...but only way to know for sure is to try something and then move on...but Like I said before, I wouldn't even worry about a couple of spots here and there...Trying to fix such a small issue will sometimes make for more issues than leaving the plant alone...

What are your water's ppms?
Do you have your municipal water report? It'll have cal/mag info, along with other interesting things like presence of chloramine.
Also, "excess P can interfere with the availability and stability of copper and zinc". I see no zinc issues there, but maybe copper; who knows. cn

Hmm.. I would be checking PH if I were you. For all you know the PH is out of whack and causing a lockout, so even though you may have Calcium in your water, they aren't taking it up because your PH is off. Without knowing the PH of the water, everything is just a guess, and that deficiency can get worse really quickly.

Today the problem looks worse, i meant to also add that i'm growing three plants all the same strain and watered from the same jug but two of my plants have this deficiency and the other has no problems what so ever. Now would this be normal that the one is not effected when the others are? If it was PH why would the one plant not be effected just kinda boggles my mind. Anyways planing on buying a PH kit and some Cal-Mag, first checking to see if it is a PH problem and then if thats not the problem then apply a few doses of cal-mag. In the mean time im going to give the girls a flush see if it helps and hope shit doesn't get to bad.

You could always buy some Epsom salt and egg shells,making your own cal/mag *take some egg shells and clean them with some water,let them dry out.Grind 4 shells into powder and add 1 tsp salt and 2 tsp powdered egg shell into 1 gallon of water.Let set 2 days or (even better) aerate before use.

Dont buy the PH Dropper kit, they only work on water that does not have anything in them. Once you put the nutes in the water, it changes the color of the water, and now the Test kit wont work, cause it uses color to tell you what the PH is. You need a PH Pen..
