I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Hey Mate, Just want to add, may you wanna have a look at this: https://www.agrobest.com.au/news/How-Soil-pH-affects-availability-of-plant-nutrients-7.htm Helped a lot. You know that your soil can easily puffer the pH of 5.2 for a short periid of time. I would adjust water pH through the whole flower on 6, and I would stop checking your run off when growing on soil. I think would just consternate. Good luck and happy trails for the rest of the way 🤞 Servus✌️ OimRausch

Seem to be doing a dance between nute burn and lockout as the ph swings in the soil. I think I may just have to flush again. using more water over more time idk.

They are still in veg and the reason the soil is so low ph is I amended it with high P bat guano. Apparently it has a ph as low as 2 and my first flush did not remove enough of it from the soil.

Not only do you need to retain a good pH for your soil, you should also be feeding phosphorus rich nutes while in flower. Make sure you're feeding your plant enough!
