I'm now thinking that she just ran out of nutrients because of her topping and the following vigorous growth. So I upgraded to the BioBizz feeding chart for the Light Mix. I used the feeding chart for the All-Mix because BioBizz recommends it for autoflowers.
Hello buddy 👋i had the same problem one time!
In my opinion the PH at the root is too acidic thats why you have a lock out.
If you have a PH pen you can check the run off water to see if you are in the correct range.
Hope it can help 😊
@valiotoro, I only checked pH here and then when watering, was always around 6.8 which is Fine singe this is an organic grow. The microorganisms should do the rest. I will test the run off next watering tho, thanks for the feedback, buddy!
