my indoor system is 2 months old. All test numbers are in range. Cucumber plants grew huge and strong, 3 varieties, trellised and lots of light. Lots of flowers, became little cucumbers. After reaching 1 inch in length, they each withered and died, from bottom of vine, all the way up to latest cukes. Removed all vines, and planted 12 more plants in other grow bed, other fish tank. And ideas why the huge loss? Thx.
