It’s getting worse

Ok so the discoloration and burnt tips are spreading and becoming more visible amd i haven’t water them in 3 days(the last time i fed them too), I’m planning to use only water this time hoping it will go away. But can this be happening because of a potassium deficiency? It has just started flowering and i’m still using veg nutes. I was planning on switching next week.
Please, i’m so worried. It’s my first grow and the flowers are just starting to form so i want them to be healthy and have everything they need

I believe we are looking at signs of Phosphorus or calcium deficiency my good sir. A potassium deficiency will start from the edges and the leaf will begin yellowing out. Phosphorus usually effects older growth first though, whereas calcium will effect new growth first (typically). From the pictures it looks like we're dealing with newer growth as opposed to older growth.

What are you feeding now, what's your EC, and what is the ph? Are you using tap water or RO?

i really have no idea about ec and ph as it’s my first grow and i haven’t find any good testers here or i have to do more research as the terms from english to my language is pretty complicated and it’s also illegal so i have to be careful about what i order online…i’m using tap water and 7-4-5 nutrients. I’m glad something even came out of the seed as they were the only “feminised” seeds i could find in the city in a cbd shop. I was lucky to even find them…so i really need to learn mire
