All of my plants have yellow spots on parts and more on others. One plant has lots of yellow spots on the leaves all over.
New growth has black tips.
There are also holes in some of the leaves that i thought were from mites. IDK though

I hope this is enough, but ill will get pictures in a bit.

Black on new growth? Is it a slimy type of stuff? Use a q-tip to see if it rubs or flakes off. If so, likely you've got mold.
Fish emulsion is a veg nute, not for flowering. (unless it's to correct a problem)
If your humidity is getting up to 86%...that's way too high. Would keep a fan on 'em.
A clear picture would be helpful.

ill get a picture later tonight.

i only used the fish emulsion during veg. and the humidity usually stays at 50. I dont know how it got up to 86, very random. ive touched the black growth and its just the leaf not mold. some leaves and stems fall off easily as well.

ive flushed several times and have been adding cal to the water and small amounts of tiger bloom. growth isnt stunted, everything just looks abnormal and out of whack. If its not a def and a lockout ill need to get a ph tester i guess.

ok this is how it is
it yellows then browns and sometimes is black inbetween the veins on the leaf and then it takes over the leaf. it is worse at the bottom, but progessively seeming to climb my babies.

The spots in the middle of the leaves looks like nutrient solution was dripped on them and left to dry, which can kill leaf tissue. But the fingertip and leaf-edge neckrosis looks like overfert. Since you've been flushing them (too much) I'm sure there's no salt build-up that FF is known for.

On most plants, black is death, not growth. :thumbsup:

Why the calcium additive, and what kind? This will keep throwing your soil ph off whack. And how much of the Tiger Bloom, and how often. Have you seen their nutrient schedule? Fox Farm Nutrient Schedule (http://www.foxfarmfertilizer.com/feedingfox.html)


growth isnt stunted, everything just looks abnormal and out of whack. If its not a def and a lockout ill need to get a ph tester i guess. Knowing your water ph is fairly important, and a question you'll be asked whenever you look for troubleshooting help.
If you are cash-strapped, a freshwater aquarium ph test kit goes for around $7.00 or so. Otherwise, a ph pen goes for $60 and up, plus calibration solution.
The aquarium test kit is ok for ingoing water without nutes, but is unusable with nuted water and runoff. It's a color-coded result, and any tinting of the water will skew accurate results.
