OOOOHMMMMM, OOOOOOOHM, now breathe karl, good in, bad out. OK, My plants will do that sometimes after applying calmag. Karl, this is hydro, If you're using a complete regimen, and suspect a deficiency, this is what I'd do, this is deep water culture if I remember right, next time you apply nutes, mix your solution to the bottom end of your acceptable Ph range, go ahead and run it, and let the Ph go all the way to the top of the acceptable Ph limits. This will ensure that ALL the necessary nutrients will be available to the plant as the Ph rises through the ranges that the plants can utilize them. If you do have a deficiency that should fix it. You have alot of foliage there karl, at this point you need to be looking at the overall health of the plant in general. I have things happening, I'll post pics, that are abnormal, possibly, but at this point they are still super healthy, and will finish just fine without a lovely cosmetic appearance. Your plants are LOVELY!
