Demande de confirmation de diagnostique: J'ai remarqué des taches noires aux extrémités des feuilles. Je pense qu'il s'agit d'une carence en phosphore? J'ai un peu tardé à nourrir ma plante. Dans mon dernier arrosage: Ph 6.5 EC : 1.8 Terra bloom, green sensation, pure zym. Merci

At week 5 in flowering I wouldn't worry to much but if you want to know what goes on for sure the you need to diagnose. Check your runoff waters ph and ec levels, and make sure their in order for the substrate you use. If ph is out up or down, that's a form of lockout. If your ec is low for your substrate then it is a deficiency. If the ec has creeped up, then you would be experiencing lockout as well..
