Help with Kindsoil

[Chelu]

Hi guys, recently I stumbled upon some problem with my plants. I grow in Kindsoil (3gal smartpots). Like a week ago I started to notice some yellowing on the bottom leaves ( on all the plants, 4)
. It wasnt bad in the begining but now they starting to die and the yellowing is happening fast. Im worried that I wont be left with any leaves till the end of the flowering cycle. They just entered week 5 of flowering ( out of 10 ). Is this nitrogen deficiency or is something else? And if it is, how do I fix it? With teas? Thank you

Can an admin please delete this post? Didn’t realize that I didnt post in the right section. I moved it to the sick plant forums. Sorry for the inconvenience.

Chelu, Morning, i use KindSoil sometimes, too.
How have you been watering your plants , like how often, and are you getting run-off out of the bottom of your pots. When you water ?
