Please save my dying plants

@b4rns 1.8 ec for autos?

Looks to me those pots are way to small for size of plant Repot them on give them only water pH should be around 6.5 water them for at least 7 to 10 days after that try a little seaweed kelp ..that should harden the plants up . Then introduce feeds but in small doses till plans tuffen up Then you should be fine Best of luck

Ok, accurate enough for me. 1.1 EC is for seedlings stage 😊 Increase EC to 1.8 including 0.3 of cal-mag (1.5+0.3)

Hi there, as you have no diary this is going be mainly guess work. Your 1st picture looks like its been overwatered, the 2nd picture looks a little like leaf septoria. Your pots look quite small and you may be flooding to frequently or for to long. Like I said bit of guess work. Hope u fix it.👍

Bottom growth turns yellow then brown, upper growth rust spots. I’m new to growing and this is my second grow.
