Weird leaf signs please help :(

when you use biobizz ORGANIC fertilizers, you aim to feed microbes, A few of them are in your Light mix when you start, but they will not survive for the entirety of your grow. thats why biobizz wants you to add them in every feed. your fertilizer works like this: Microbes get into the soil, you use biobizz as feeding so the microbes in your soil start to eat them up. They than will produce the food your plants need and make it avaliable for you. You are basicly a middleman with your kind of fertilizer. seems like not alot of microbes are left in your medium and the nutrients cant get to your plant efficiently anymore

I dont know if your diary and the quantities are accurate, buy why do you use so much bio grow and bio heaven. At this stage i sometimes dont even put bio grow anymore.

I'm kind of new still myself, but to me it looks like potassium deficiency as well as some ph problems. Potassium usually causes brown leaf spots on edges and ph will cause the leafs to twist like I see in your pics. Wrong ph means it can't take in the proper amount of nutes. I would give a good feed with ph balanced nutrients. At this phase should be some nitrogen, but I think you need to use more bloom. Also i see you mentioned a new light in your journal. Making sure its at the right distance or it can also cause the leaves to fade. Again I'm still kind of new and I don't use those particular nutrients either. Just my thoughts and I'm curious what others have to say.
