    looks like the start of magnesium toxicity to me especially with the upper growth being affected first,
    just flush/feed with water a few times, skip a few feeds matey ''jmo''

    Makes sense mate since I use MagiCal 5ml in 5l water with every other feeding thinking to actually help the nutrient intake but maybe she doesn’t need it?

    Ok so I have skipped a feeding once and now I’m worried if it’s not a potassium deficiency? I am so confused with the rusty leaves





    Thoughts?

    Also it is happening at the top and middle of the plant and not really the bottom... potassium deficiency moves bottom to top right?

    you damaged them slightly with the excess magnesium dose, once damaged they won't repair mate
    all you can hope for is it doesn't spread before it gets corrected,

    -added
    people have killed plants by overfeeding cal/mg/epsom when the plants weren't showing cal/mg deficiency

    Wow I hope I didn’t fuck up! I have stopped the magcal completely. Next feed I’ll go half strength of nutes. What do you think? Thanks again for all the input it helps big time

    if your in doubt simply flush the medium with plenty of water and feed at a reduced rate like you are already,
    soil shouldn't need flushed but sometimes it's the lesser of two evils

    magnesium in a high enough dose is absolutely toxic to your soil/plants hence why they yellowed so quickly,
    but looking at the before and after images it hopefully hasn't spread down
