Well I’d invite the grower to the forum for a quick discussion but it seems to me they are using un ph’d tap water in their plant.

Slight curl/twist to the leaves is a good sign the input is off. They’re slowly killing it and not realizing this, have them get a ph tester and get within a useable range for nutrient uptake for the plant. 6.7 . Also how long have they been in that soil? It only holds for up to 6 weeks or so before it needs supplements


I’m here . I’ll check the PH last time I checked it was in the 6-7 range. Soil is about 5-6 weeks

Do you have a suggestion on supplements ?

These look to be munched on. Cats and dogs like to eat the leaf tips like that.
