A pk burn if one of the worst things that could happen to this plants. The affected leaves will never recover and continually look worse but the flowers will benefit from the extra dose of nutrients. Just back of on the feed, alot. Keep using plain water maybe do a water, water, feed, schedule at half the amount or less nutes

Do these look healthy? Thoughts? I'm new to hydro/growing I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.
