Plants don't seem to be taking water

I have two plants that seem heavy,and some of the leaves have yellow tint and brown at edge. I did a flush and ph is 6.5. Any other suggestions. My eight other ones are fine. Won't let me upload pics.

sounds like a "flush" may not have bee needed after all

I've seen this happen in flower when I've over fed, soon as I see it refusing to recover I throw the plant in the compost and learn.
some are fussy, and those are the ones that have no place in my life lol

what stage are the plants at, what are you growing in, what are your temps like night and day ?
