Dark phoenix and blue cheese

Hi guys So end of week 4 and entering week 5 now. Few issues this week with the feeding of the plants. Dark phoenix are hungry well half of the plants are anyway 🤔🤷‍♂️ so I upped the feed to 1200ppm the dark phoenix didnt mind it as it needed it but my blue cheese suffered and has significant burnt tips on every leaf 😅 I will disconnect this from the auto feeder and flush and add half nutes by hand in a few days. Othere than that the plants buds are growing and getting frosty. Thanks for looking and happy growing guys👌💪💚 Day 37 flower I changed the marshydro tsl2000 to a 400watt hps to finish the job on the scrog along with the bloomplus bp2500 250watt led light. So cheese got burnt quite bad I totally disconnected it from auto pot system and feeding ph 6.5 water only for a week. Dark phoenix is really frosty now still loads of pistils standing on end and filling out now and smells amazing. The next 2 weeks I will keep feeding bloom and top max then I will start the flush on them. Happy growing guys.
