How are you checking PH? Reason I ask is I suspect you have some kind of nutrient lock out. If using a ph pen be sure to calibrate it regularly (every couple weeks).

i’m using Awda ad11 pen
and a aquarium ph test to check if my pen is alright

1L water - Biobizz fertis - check ph thens i use phup

Are you checking run-off pH? It could be a phosphorus deficiency due to too low pH.

 

[Rwise]

Not what with but how, what is your procedure?

 

[jonnthelad]

1step - 1L water
2step - add nuts ( im following this calendar: https://images.tcdn.com.br/img/img_prod/594227/kit_biobizz_biobloom_biogrow_325_4_20190829171753.jpg )
