Severe calcium deficiency?

Defeciency's are always caused by overwatering or ph issues.

That may be a fungi infection. I would first try to spray for that and rule it out.

Make sure your plants are very dry before watering. Dont be anxious to give them a high ppm count of fertilizer. Less is always better and overfeeding can cause tons of issues.

Try doing a ph test of the very first drops of water that come out the pot after watering. Lime in ur dirt will really help with keep ph in check if you mix in before you plant.

Your problem doesnt look so bad now but trust me if you dont correct it will get much worse. Anytime you try to correct something give 1 week to see if it helps, dont expect a miracle over night.

If leave start to really discolour use advanced nutrients "revive". This stuff i have seen with my own eyes green up a plant in a hour. It will be a great help keep them healthy until your problem is solved.

Fungicide first while foliar feeding revive then wait and see.
 
I have similiar problems with my plants, I thought it was LED lighting that was the problem. But I also use Canna nutes and have the EXACT same problems with every plant.

I will take and post some pics when I get home. I've been banging my head on the wall trying to figure this out also... driving me nuts.
