Probable phosphorus excess nutrient block
Hi, I was wondering how long are the nutrients blocked after an overfertilisation ? I lowered my EC to 1 (day 24) since they are growing a 3rd internode. Thanks !

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.

Magnesium Deficiency ? How can I fix it ?
got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?
