@MidwestGuy true. But he is in veg rite now which is easier to nuke. So starting low and gradually getting to reccomended dose is best.
Thanks for all the input!!! I’m learning so much… I trimmed the bad leaves off… rip to my fallen heroes who gave they lives so the plants can flourish! 
Looks like calcium won’t be absorbed with a PH above 5.9 so although it could be lacking in the water it could be there but just not being used due to the PH
As far as removing the leaves…if on there they will supply other areas of the plant some calcium from those leaves. Until things are corrected the plant will take calcium from other fan leaves to help with new growth…up to you on removing or leaving them on.
I’m not hydro so as far as PH/cal availability I may be off but charts I’ve seen for hydro show cal and PH as posted above
