Are those plants thriving other than the yellowness? Either way, I know some eople that ride teir nutes at double what you are thiking of gowing, so you should be fine either wat... I just know some strain and some plants just use all the life in the when flond some I have see stay green from head 't toe.. Just make sure you do what is best for all your girls, don't get too caught up in a few that aren't perfect and jhealth of any others. It will bug you more if that happens[/
