Hello, I am having some leaf issues with my frisian duck plant and can't tell whether this is leaf burn or nutrient deficiency due to being colourblind, can anybody help a fella out?
They're in biobizz light mix and I have been giving biobizz fish mix liquid nute, small amounts of fulvic acid (root boost) and unsulfured black strap molasses. Usually i have no issues but I had to hide them at a friend's for a few weeks and had no way to give her anything but water and now it looks maybe deficiency or light burn maybe? :/Tell us what medium they’re in and your feeding routine.
Looks like phosphorus deficiencyThey're in biobizz light mix and I have been giving biobizz fish mix liquid nute, small amounts of fulvic acid (root boost) and unsulfured black strap molasses.

Far moreI thought phosphorus was unimportant during veg..?
Well when you have phosphorus deficiency it doesnt properly injest zinc , iron calcium and magnesuim. So on lower leaves it will show thisThat looks like magnesium to me. It seems like Mg deficient leaves are prone to light burn.
That's all fine and good, but the symptoms this grower has don't look anything like the pictures you're showing from Dutch Passion.Well when you have phosphorus deficiency it doesnt properly injest zinc , iron calcium and magnesuim. So on lower leaves it will show this
Suggest a P/K boost of your choice. Might as well give both.It could make sense as I did give her a dry fish blood and bone mix with a 4-2-4 npk but this was about 2 months ago and I've not given her any phosphorus based nutes as I thought they were just for flowering lol I shall update the results soon when I add some phosphorus in her diet
I've given her 1ml of biobizz bloom as well as the original nutes, I pruned and milk+water sprayed her a couple days ago due to a small white powdery mildew issue which seems to have cleared (for now) but from my past three previous grows I've never had any issues like this so I think ik where to come for advice from now on, thanks guys!Suggest a P/K boost of your choice.

Is the an NPK test for soil?Far more
“Phosphorus is, therefore, important in cell division and development of new tissue. Phosphorus is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.”
