Some on leaves - Help!?

hey there , looks like a (rare) magnesium lock out, most people have the opposite problem but seems there has been a build up from using two souces and plenty of things to make it available. it's the worst possible time to disrupt the plant but you do need to flush : water until run off then water again with 30% of the initial plain water quantity to get a good amount of runoff then next watering cut back the nutrients quite a lot and hope for the best. Hope this helps ! 🚀

Hey buddy :-) If you haven't even too much before fertilized and it is a lock down, then I would say that you have a deficiency. Raise the feed a little and keep it up. looks great 👍🌱

Hello, I think it's a lack of phosphorus, don't hesitate to give it more phosphorus, it will do it good. I add some as soon as I switch to 12/12. I hope my advice helps you, feel free to come talk to me if you need anything. I'm also open to any good advice! 😁
