Purple lemonade + dr jack $$$$$$$

The bad boyz r growing rapid, the purple autos reacted to the fish mix a lil as the tips went slightly yellow after adding this to the feed but it’s not a major issue Not sure if it’s that or some other problem, I will add cal mag later on in the week if it continues to worsen but it seems to be only the new growing leaves that have reacted if any1 knows why this is plz feel free to help a gal:) started defoliating the plants not to much tho just enough for the plant to open up more. Ahhh there just bloody beautiful aren’t they 🤯
