Yea. Just some minor burned tips. You’re ok my man. The leaves are telling you it’s absorbing max nutrients for the current day and can’t handle any more. I max my plants as well - and when I see this - I give them a nice 2 day feeding of plain ph water to absorb what ever else is in the bag and then continue on with elevating nutrients. They will adapt. Like grannie said - it won’t repair - but who cares…ya don’t smoke or save that stuff mostly anyways. Focus on the buds.
I, becoming a fan of tps signal for end stage bloom. Ran it with two plants - one has it - one doesn’t….and the results were amazing. It’s drying now - but I think double yield. Safe during flush.
