Unsure of nutrient burn or possible other issue? Outdoors first grow

[VTfarmerguy]

Hi all,

have three outdoor females doing pretty well - used LST on them to spread out potential yield - but am noticing that some of the leaves are displaying signs of nutrient burn/possible fungus? Again, pretty new to this but would like to figure out ASAP. Not I have switched in last two weeks to using fox farm’s Tiger Bloom Liquid Fertilizer so it may be related??

thanks!

Looks like a few different things to me.. more like a nutrient deficiency.
How much PPM you feed them?
Do you give them extra Cal-Mag?

If it was a nutrient burn the tips would be yellow.
