Need help diagnosing issues

[Triple R]

I have 2 white widow Auto flowers week 2 of flower. In coco/pearlite 3 gallon fabric pits. Mars hydro tsl 2000. 24 light cycle started seeds in pots temps a lil warm from 79-84°f. 50% rh. Smaller one green and healthy. Bigger one is getting issues, leaves turning yellow with brown spots curling tips. Feeding with humbolts call/mag plus iron and GH trio about 3 ml each per gallon. Need help identifing what's wrong with her. Nitrogen? Potassium? Only my 4th indoor grow and I'm still learning. Many years gorilla grows in woods never had issues. Just plant in spring harvest in fall. Nothing in between. First pic is the small one. Rest are large one with issues. Anyone with indoor exp. Help please

hey @Triple R
i dnt know those nutrients but give them a bit less. you said 3ml eacy per gallon then i would say do 1.5 and see how the new leave growth is. If it was good then give it 2ml. You need to find that sweet spot.

Thanks I flushed them out and cut back like you suggested. And the turned the corner. Here she is a few weeks later in week 5/6 I lost track.

i never said flush it. you should never flush a plant in soil. You only stress them more.

youre first set of pics vs the 2nd set of pics are different? im confused

It's an white widow auto flower In week 5 since pistols showed up I'm in coco/ pearlite no soil this time . Now when she's done I have 4 super skunk 1 purple Haze and 1 blue cheese all fem plants that just sprouted that I'm going to run in organic living soil with slow release dry fertilizer. I flushed the auto in coco cause I burnt it with liquid nutes and some shit someone gave me called big bud enhancer. They came around now n buds are fattening up nicely. Thinking I have at least 4 weeks to go. My last white widow Auto took like 10 weeks in flower.i lst this one and it filled my 2 1/2'×5' closet
