Help deficiency

Again, Your plants are suffering from nutrient lockout which normally has something to do with pH which I didn't see listed in your diary .... That's a problem if you're not checking it. This is why the plant is showing signs of so many deficiencies like potassium and calcium even though you're feeding them. Flush the plant, then make sure to keep your pH between 6.0 and 6.5.

Hello Growmie! I would firstly look at the PH of your growing medium. All your symptoms to me seem like imbalances due to lockout. Get some strips or digital tester and correct your PH! Good luck!

looks like a PH issue to me, whats your PH? I don't see it anywhere in your diary.

Watering 0.4L/day is not enough and that's why your plants show a generalised deficiency. For a 11L pot, you should water around 1.6L/day and enough for the pot to drain a little waste water from the bottom, carrying away residue and renewing oxygen in the roots.
