Plants turned 30 days old today. Have them LST'd pretty low and even. Yellowing tips on newest growth on plant that started throwing pistils yesterday. Watered 4 days ago, 1/4 strength nutrients. Any clue as to what could be causing this? Will probably need to water tomorrow, and am wondering if I need nutrients added, or just plain water. Is she starving or overfed? or something else completely? Would appreciate any advice, and thank you in advance!

They look underfed to me.

Am a sunshine #4 user, its pretty mild stuff, good for a couple weeks from sprout, but then will need to be supplemented till harvest.

I find the SS#4 really nice as well.. I tried a 1/8 Str nute feed about week 3 and got a few burned tips.. nothing major so i held of for another week then went 1/4 strength.. now im wondering if thats overfed or underfed..lol

Can't speak to your nutrient line, I run Nectar for the gods, and it is a completely different beast that uses the calcium molecule to carry other nutrients to the plant, every other nute line I've run across is salt based.
Salt based nutes will burn easier than what I run, but I'm normally at 100% of feed by the time I'm into flower.
There are strains that are sensitive to higher nutrient loads, but, have found the majority of autos I've run aren't getting anything different than my photo girls always did.

Many strains, like ghost Toof and sour crack would take anything I gave them, was at almost 200% of feeds by the time they were done.
