Personally to me it looks like K deficiency and mg deficiency starting, Kdef is often confused for nute burn when it first forms. If u are using tap water, or anything with Calcium in it (besides nutes) u need to stop! Ca will lock out K and MG when over applied.
If I am wrong and it is nuteburn then here is some feeding tips. When u feed soil u need to feed about 350-450ppm every feeding or 1000-1400ppm every three feedings, with plain RO water in between. If u use RO water the only water that should be PH corrected is the nuted water, the RO water should be left alone. If u use tap water, and have no other option then u need to get hard water nutes (nutes that don;t contain Ca and Mg).

go to walmart and buy the value brand drinking water (it's reverse osmosis), also see if they have a RO water dispenser and u can buy the water for about 30-40 cents a gal.

you can use distilled water too.. don't use spring water because usually has a 6-7 ph and still too high.
