New grower here. Partner and I have around 25 teenage plants indoors under MARS ts1000 lights.
Growing medium: mix of coco (1/3) and ProMix (2/3)
issue is that the growing medium pH is stuck around 7 which Im pretty sure is causing issues with nutrient uptake. Some of the smaller ones have red stems and dehydrated looking leaves.
I had some luck watering with 5 pH water previously and saw another post on doing an acid drench of 4-4.5 water, but my partner wants to keep using 6 pH.
What should I do? How can I get this growing medium more acidic and have the ph stay there? It always seems to return to 7 within a day.
Using Rootfarm pH down.
