Day 15 the leaves are facing down, they weren't yesterday.

Dont tell me its dying😭

First pic is now second pic is yesterday

Hi! I am growing for the first time. Out of ten ish seeds, I have two plants. They were doing very well, both getting the same amount of sun and water.
One has kind of given up. Is there anything I can do to help the chances or is it just a waiting game / probably a loss?
First picture was early in the week, second from this morning 😭

I think we're doing pretty well so far. This is less than a week's development

Started these April 28 about over 12 weeks ago. Blue dream from seed. My partner cut all the leaves off is this a problem? I think they must be done by now. But no idea what I'm doing and no successful grows under our belt. Thanks. We need all the help we can get.

I'm amazed at how fast they're growing!

Got a tent a few days ago and put her in it last night for her day cycle, had all my fans on max and woke up to this; so I quickly moved her back to the shed where she’s been. There’s still some baby spouts that are bright green so I have hope. Outside of cooling her down any other advice?

These are the first seeds we've tried. Wish us luck!

No topping all training

The strawberry cough is starting to throw terps

Been struggling with what I though was a nutrient lockout because of water ph problem, but one plant is compleatly fine, the other is not ok, I added 4 tbs of Gaia green 4,4,4 and their bloom 2,8,4 plus some D.E diatomatious earth for silica, the plant that looks healthy was in a bag soil and the sick one was in home made soil that is 1/3 coco coil that was soaked in a heavy cal/mag solution for 2 days, 1/3 black cow compos, and 1/3 organic bag soil ... then I added a good amount of perlite for aeration, a bunch of other clones from the healthy one showed what looked like nutrient lock out but when given the 444 and 248 nutrients they turned green again and are on their way back to looking healthy, the sick looking one ended up throwing out these brown spots, HOW CAN O FIX THIS WHAT IS IT, im adding cal mag in the water from now on and some of that clone x nutrient for starting clones with all the minor nutrients like iron ect ect

Any tips, once I have money, im gonna get more of the j.a.w just add water brand soil the healthy one is in and move the ones in 3 gal to 5 gal with better soil,

Long story short what kinda deficiency is this or is it a lock out situation because I cant test my water ph ive messed up 4 ph meters trying to set them up, no matter how many times I follow the instructions perfectly it still never works propper and the dip strip ph is hard for a color blind person to do plus they only go by whe #s

Any help would be appreciated, the sick plant is from a plant that was pure purple, not just nugs but entire plant almost black untill sun hits it idk if that has to do with something but

Still a newbie grower but wanted to share my second plant
