Leaves have weird Spots on them

she had enough nutes.. I see this often with BioBizz.. ( i dont use it btw) seems like a very strong nute that can cause nute burn very easily (and nute lockouts) just give her some fresh water for a while and just continue with half dose of bloom nutes (calmag and fishmix i would stop with those) so it wont get worse good luck

This one could be K-tox Would need to know how it progressed and even then may need to eliminate multiple possibilities. High potassium can lock out Mg and Boron. High P could lockout things that look like this too. This looks like more than 1 thing, so nute lockout or pH is something to investigate or consider. the messier it is to diagnose the more likely these 2 things are the cause.
