Question for the Pros!! PICS!!!!

Hello, thanks for taking the time to help me out. I have posted some pics below and wanted to hear a few opinions on what may be causing the discoloration of my leafs. My temp is 75-80F, 45-50 hum 5.8-6 ph,1100-1200 ppm and im in an ebb&flow using t5's for light. These plans are about 2.5 months in and getting ready to transfer to flowering.

Your thoughts ?????

What nutrients are you feeding them?

when was the last time you flushed and refilled your res? are you constantly adding ph up?

Im using soul grow and roots organic. I flush every 7 days and did about 3 days ago. I am constantly adding ph down, but recently some ph up when I last changed my res.

too strong nutes, too often???

looks like too much nutes to me, back down to 800 or so.

The nutrient streetlight you are using is correct for hydro, in soil that is way too much, I would stop fertilizing all together. In soil I use 400ppm

gonna agree to back down the ppm's. also watch for signs of salt build up

It is hydro and the nuts have been the same for a few weeks with no problems. I did change from feeding 3x a day to 4x a day but for the first week they loved it and only one a few are showing these signs? Thanks for all the coments keep them coming )
