End of week 4 of flower and plants are looking good except for the one plant #2 which still has the copper coloured spots on quite a few leaves and purple stems as well, going to bump up the cal mag on next watering, was worried about fungus nats, only seeing a few now on yellow stickies, but thought maybe the larvae got to plant 2 so I added nematodes to all plants 2 days ago, can’t hurt right ? I WOuld really like to hear your thoughts and recommendations.
