Problema con mi Runtz Muffin
Buenos días, Tengo un problema con mis hojas, (puse fotos para que podáis ver). He visto que podía ser un deficiente de fósforo. Pero también puede ser un problema de calcio y de magnesio. Alguno podría ayudarme con eso ? Que tengo que hacer ? Añadirle un PK 13-14 ?

I'm still trying to raise my soils pH, I'm using Olympus up which has lime, should I give a higher dose or jus pH water till pH runoff goes up?
If I use nectar for the gods Olympus up which has lime in it and I'm having low soil pH probs, should I use more Olympus up and adjust my pH and would that help raise my soils pH? Or should I jus use pH water until my pH runoff is where I want it? Advice greatly appreciated.

Another round of Name That Deficiency
5 weeks into flower and this plant seems to be the problem child but she’s also the one showing the most growth. PH is 6 on her, was originally 6.2 but was having a manganese deficiency so went down to 6.0. Gave 3/4 of recommended nutrients in last feeding. Not sure what to do.

Soil pH is surprisingly high. What's the best/safest way to lower soil pH (without eliminating nutrients from dry amendments)
Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?
