It was the same light and just so everyone knows it was........ Wait for it......... Magnesium def. I got some Epsom salt after I did a huge flush and did a spray and in two days I'll water with 1 tablespoon of it in the water... I sprayed and they already look so much better
1 tbs is a lot
I wouldn't continue with that much
cut it back to 1/2 tsp moving forward
also consider your not magnesium def, you could have magnesium lockout from over fertilizing or from to much of another lement like potassium or calcium locking it out .. theres also a chance you could have a PH issue as magnesium can get locked out if the ph is out
all of which a foliar feed would help
so theres some questions you still have to figure out
foliar feed and adding Epsom alone might fix it but it might only be a temp fix
