Hello! My dad poisoned a lot of stuff in my garden w/ roundup (not what i would’ve done but it’s cool) and now the new growth on all 14 of my tomatoes is a light yellow. What should I do? Thank you! (Pictured above is a plant that’s struggling a bit more than the rest, most of my tomatoes only have light, but noticeable yellowing at new growth)
