Discolouration of leaves
These plants were moved outdoors recently, 2 of them are showing strange discolouration on the leaves.
At first I thought it was a pH issue as the soil was reading around 8.5. I amended with vinegar until the pH was 6.5. It has now been two weeks and no improvement. Picture number 2 is taken from today.
200L base soil mix
5.6kg plagron worm casting
5kg plagron bat guano
÷ 5 = 1 pot
Both are Holland's hope, I live in the Netherlands so the temperature outside is ranging from 15C during the day to 5C at night. I realise this is far too cold but I had no choice in moving them outside
It looks like you maybe have a bug problem mate, signs of thrips there. Also, that whiteness looks like powdery mildew, does it wipe off or has they leaf lost colour?
ah this will be down to the neem oil solution being too strong i think. Sray the plant just water to try and wash off any excess neem oil. What neem did you use?
Looks like an Iron deficiency causing leaf chlorosis, new growth bright yellow, older growth brown & crispy at edges...
Is likely caused by bad Ph (as this will block Iron uptake) and maybe over watering...also vinegar is not a good Ph down, its only really a temporary fix as it breaks down in water
What is your base soil ?
