You need an EC/TDS/PPM pen! Without knowing soil makeup, and from the looks, it appears to be Potassium deficiency.


Hello @Nofkkr and welcome to the forum. That super low pH is the source of a lot of your problems. If you have baking soda there use that to bring your pH up and then have a go at finding out why it’s so low. Pine needles or peaty soil could be a starter for 10. I’ve stuck a pH chart in for you to give you an idea of what happens when your PH swings away out :sunglasses:

Are the leaf tips curving up and crisping all over?

Its cal mag issue wich might be a uptake issue caused by a tox of a macro like potassium or silica. U might have a high ph ground base wouldnt know it untill u have dirt tested or do a ph slurry test id do the slurry test with a powder reagent falllout a few minutes to follow match up the color …i bet you got basic as in abover 7.2 ph dirt if thats the case dig up your baby and your gonna have to clean up roots and dig a big prebed ir burry a kiddie pool fill it with dirt and it will keep alot of the surrounding ground leaching into your choice soil
