Nutrient Deficiency or Nutrient Toxicity? I CANT TELL!

@Mr. Grow It Will do. Last question, Im putting my plants into flower and was wondering how long it should take to change the lighting schedule (Maybe a week?). I also have a RED bloom setting on my LED and was wondering when I should turn the light to plain red. Thanks so much, you're a legend!! 🙏👏

@Aidan Kenealy Once you flip the light cycle to 12/12, many count that as day 1 of flower. Although, others will wait until they see pistils and then count that as day 1 of flower. I think that answers your question? If you grow light has a switch for Veg and a Switch for bloom, most likely it's best to keep both switches on for flowering.

@Mr. Grow It Okay yeah I got it, I just thought about something. My coco must of been at a PH higher than 6.5, meaning that iron was not able to be taken up by my plants. So I did a flush last night with just calmag. Now when I feed with nutrients on my next watering ill be sure to aim for a low ph around 5.6ish so I can bring the ph of my medium down. I also sprayed all the new/yellow leaves with chelated iron to hopefully bring back some of the chlorophyll I lost.
