That is not damage from foliar feeding. It is very hard to get damage from foliar feeding when you are using fluorescent lights. The most common damage from foliar feeding results from powerful lighting being magnified by water drops on the leaves, and fluorescent lighting is nowhere near powerful. What you have is the beginning stages of Nitrogen deficiency (the slight yellowing between veins) and a cal-mag deff (the darker spots on the tips of the leaves). Good luck.
What "foliar stuff" was that?
Lemme guess you for forgot to spray with plain water after 20 minutes and let dry? Only reasons to foliar feed is when you know your plants aren't getting enough food or has a deficiency.
From the looks of it your new growth is yellowing which means you have some cold nights? Also looks like ph too high and the start of a calcium deficiency,which temps and ph can lockout.
Also looks over watered and heat stressed,did you spray when the soil was dry and then water?
folier still must be phd
and must be a weak spray not as strong as feedig
Couldve burnt?
From all the research I have done deficiency is not the only reason to foliar feed I don't know who told you that, but there are plenty of foliar appliations that are dierected to be used once a week or once every other week.
Also if you look at the pictures they are in cubes not soil.
Also new growth is not yellowing it is just light green because it is new growth....
I feel like I shouldn't have to say this... but perhaps you should try and not be an arrogant asshole to the people TRYING to help you. A shit attitude is pretty much a deal breaker for most.
I realize this may be a difficult concept for some people to understand, but there's no reason for that. Good luck anyways.
Yeah i said REASONS =food and deficiency,sorry i missed the cubes.
