SOIL Please help diagnose

[Lilbit6586]

Looking for some guidance, as there are some definitel similarities between different diagnoses. Please see pics, this is one out of four plants in the tent, this has advanced symptoms, one other is just showing small signs of this, two others are absolutley fine. I am thinking calcium deficiency, as I had this with a plant before and CAL MAG seemed to have stopped it, but with the elevated PH I am not sure. Also, just minutes ago purchase a ph pen meter and will have more accurate readings. Any help greatly

Setup:

Clean 8'×4'x80" tent
LED light panels, adding panels as needed
100% Happy Frog Soil
Just transplanted from 5gal fabric pots to 15gal fabric pot
Fox Farm Trio-Grow Big every other watering, water every other day as needed
Strain-White Widow
PH is high, almost 8, but that is with a $6.00 3 way meter u stick in soil.
Well water, PHd at 7-8, high, tested with drops
Have not been able to collect runoff for PH reading yet

How about a pic of the whole plant, better yet the plant under natural light or atleast with the flash on. Would make it alot easier to diagnose the problem. Could be a call mag problem or lockout with the pH problems you're having keeping the plant from taking anything from the soil but water.

If you have 10 gal. of fresh soil in the pot I would flush the center of the pot where the old soil is with a couple of gal. of water, if you get one of those plastic squirt bottles of lime or lemon juice concentrate from the produce section, give each gal a 2 or 3 second squirt to lower the P.h. then, final gal with a dose of cal mag also. give em a week or so to snap back. Good luck. Oh yeah, lose the lights and get some better pics.of the whole plant.
