im Just starting out myself but FFOF soil is good for about 30 days your close to that I’d say there probably hungry but you would need a ph and ppm run of test to say for sure I dont want to give bad advice. It could also be over watering if your ppm and ph test is in the right range.
What is the pH & PPM of the runoff?
people will need more info like ph ppm how often you water flower or veg what week your in
