its getting worse

Your best bet would be to brew some EWC/compost tea to water with. There are many different ways to make it. But in your case just castings and some compost or Ancient Earth would be the way too go.
Heres a like to a thread that may help: https://www.rollitup.org/organics/338669-my-organic-tea-recipe-thread.html

Beggars cant be chooser ya know! Just kidding...and while waiting for the tea to brew some 30% or so H2O2 added to your waterings couldnt hurt. Like a tsp or 2 per gallon. Will not hurt a thing and can only help....

Embarrassment. I finally got a digital thermometer, put it on the floor under my T5, overnight....

94 degrees. WTF

I put a fan in the box.

Maybe caused some issues?

please dont add h2o2 to your soil, you will just kill all the bennies in there. h2o2 works for hydro but doesnt do a lot for soil.

So there is different bennies living in soil than hydro? Hydro vs Soil, which digests urea best? Hydro bennie vs Soil bennie that is...

EDIT: FYI a soil grower could not produce a corp without hydro, you know H2O....

I'm wondering if this plant made it.

She's changed very little. At this point, she's not growing but she's not dieing either. I guess it's just a waiting game right now.

I appreciate the concern. Thanks.

My thoughts are, you are over caring for your plants. Too much love is a easy thing to do when first starting. Its a weed man, let it grow like one, plant it and forget for days. Judging from your pictures I see 2 issues, over watering and several deficiencies due to lockout. My advice, get your ph under control, figure out your soil ph, figure out your tap water ph, figure out what ph you should be watering with and no nutes till you are couple weeks into flower. H202, teas?? Quit making weed growing more complicated, its a weed, let nature do its thing. healthy plants first, add to the equation later. Back on PH, last time I used FoxFarm soil, though it ended well it did not begin well. Soil was too hot for my seedlings but they managed. Also after some time of me watering with non proper ph'd water, the soil ph ended up getting too acidic and caused lockout such as yours. Thats my experience and my .02, GL.

I need help I'm new to this. I'm using a bubbleponics 6 plant set up but only growing 2 white widows, ph is at a 5.75, 12.5 ml floragrow, 12.5 ml floramicro, 5 ml florabloom in 5 gal tank using distilled water in the 5 gal jugs. They are 3 weeks in veg, humidity is about 40-50% and temp is around 80F, 4 cfls at 3600 lumen per light,2 6400k and 2 2700k. I got dry and brown spots on the leaves all over the new growth isn't bad but the lower leaves are. Here's a few pics need help right away.

Looks like a calcium deficiency. Try using your tap water instead of distilled. Distilled water is a poor choice for growing.
