    You may have a case of light burn/stress. How many watts are your LED lights and how far away are they from the plants?

        I have 2 - 300 W led lights at about 18" above the canopy also note the pic above of the single leaf is a bottom leaf below the canopy so it does not get a whole lot of light

            these pics were just taken within the hour this evening... I had done a flush 2 days ago, stopped feeding the cana A only giving cana B and canazyme, also am now adding tiger bloom... I can't say if they are getting any better or not yet I figure it will take another couple days to see if anything good is happening.. the first photos I put in my first post here were taken 2 days ago just for reference another thing I need to mention and don't know if it is right or not but some of the pistils in the flowers are turning brown/red color

              Today's pics look much better than those in your first post. Try raising the lights a few inches as well. Though they're 600W and run a bit cooler than HPS, the LED light spectrum is still pretty intense if put too close to the plants. Hope they continue to recover.

                        If you leafs are falling off it may be a Calcium deficiency what's that situation?

                            Yes I would push it to 5 ml per gallon. For a water or two to see if you notice a Improvement.
