are most plants viable?

i run a bunch of strains at once across a couple tents. 5.8ph, add 250 to 350 ppm of gh floranova grow, 15mlH2O2/gal, sometimes adding a small amount of calmag or AmorSi. 100% perlite hempy 2gal.

my first grow in this location/setup was with 3 strains went really well. they grew great. i didn't have any deficiencies or anything. got ~45g/sqft. off 7 plants.

the next round totally sucked. perpetual deficiencies. ph was off, until about week 3 or 4 of flower. i didn't catch it early for a few reasons, one being that not all the plants showed problems. yield is about 1/3 of the first, but the flavors are fantastic. i still have an ACE seeds at f85 i haven't taken down.

now on the third one, in week 4 of veg. since sprouting, some of the plants just seem to suck. one in particular, the girl crush from twenty20 is just trash. it just doesn't want to eat, it's stretching all over the place, and the leaves are yellowing from the bottom and dying off. i have a few other the lowest single leaflet leaves are yellowing, getting spots, then slowly dying off. the rest are doing just fine. 6 are under the ACI s33 with a range from disaster to perfect. the others are under an old vs450 with blue blurple turned on...they are doing great.

speculating:
it could be the lights, but the first grow flowered and did most of the veg with the s33. the medium is perlite, so drainage is great.

it could be a mag deficiency. i have fed with calmag. i have epsom salts, but haven't run that yet.

it could just be bad plants or the wrong genes for my setup.

i spayed with an anti fungal in week 2 in case it was rust mold. i don't think it was. the plants didn't really like the anti fungal, but bounced back after a day or two. leaves twisted a bit, but then returned to normal.

i'll get a pic up a in a bit.

When you post pics tell us about the medium you’re using. Including container size. By the way the ArmorSi you can forget about. It’s only recommended using every time from the time you start feeding. Intermittent dosages are probably useless.

What are your temperature and humidity averages/ranges

One great tool is a temp/humidity logger

I wonder if you had a better success with higher temps and now that it is colder and dryer things are different

See if you can get that night temp up to 68 or 70 and day temps up to 75-78 at least. It is hard getting a tent so warm because it makes the living area too damn hot

Under LED( ac infinity 33) you need to have higher temps than is comfortable in your house. Also you should be sure you aren't giving them too much light (easy with LED)

Too much light in the winter might be the perfect amount of light in the summer due to higher temps and production from the plant. It is able to digest more light with better environmental factors

Also genetics can be an issue, but I'd start with working on all parameters of your grow and figure out what you changed this time from last time.

Is the hempy on a concrete floor? Cold roots can be an issue. If your temps were higher before I'd start here

The first two are under the blurple. The others are under the s33. Hempy perlite 2 gallon.

sorry, i didn't mention, it's at 40%, so not too much light and it's at like 33 inches or so away. the vipar is 90w of blue. this is indoors, but it is colder in the winter. like low 70s or so with the light on. i the viapr tent doens't get air flow so it's hotter. vpd is probably better. a couple plants had issues in the vipar tent at sprouting stage.

the purple stems tell me lockout either due to pH or temps

Is this fresh or re-used perlite? If re-using perlite I'd recommend pondzyme or something similar to help get rid of dead decaying roots from last grow. Are you going 10-20% runoff and getting rid of the excess runoff? Drain to waste is essential with hempy. Hempy's need this to avoid abundance of nutrients in the medium, especially if your nutrient feed isn't exactly what it should be
If you are doing exactly what you did last time when you had great results, Id start with adding some heat and seeing how they react

other than that I have no experience with flora grow maybe that is the issue; unless it worked fine last time.
be sure if using armor Si you add it first, then let it mix, then the rest. I use the GH 3-part I love it. This time I'm switching it up. Hope this helps man they don't look too bad I bet once you get this figured out they're gonna take off

new perlite. coarsest i can buy from the hydro shop...the amazon stuff is broken down too much. i have grown many times with this brand...i am at the end of a really big bottle...that could be something to consider. also, you may be right about the temp...best one inside was in summer/fall and the house was 71 or so. lately, i've been running the house cold because of dry/cure from last iterations.

I'd see what you can do to raise the temps first before you go chasing your tail on other factors it could be
what you've done before worked so if thats the only variable besides the seeds you used that may have changed, I'd work on seeing what you can do about that

perhaps dropping the light % then getting it closer to the plants, putting the exhaust on the bottom of the tent to draw the warm air down, or putting it in a closed room with a small heater or adding a heatmat to the tent.

Nice setup by the way!

It would be the easiest thing to change IMO with little cost , it might take a week or so to get them out of the cold lockout.

I'm sure there will be an easy way you could figure out to increase your temps a little bit

oh yeah try getting one of these perhaps @Inkbird could send you one. They're only like 30$ and well worth it IMO!!

thanks man. i have another dual tent across from it, will move 4 there when it's free. will do, i have an extra temp controller. maybe get things back to the high 70s. the fans are on all the time mostly to control humidity on the last flowering plant i had across from it.

Do you think it would benefit to link one tents exhaust to the next tents intake? It may be an issue later but for now it might add a bit more heat to the second tent

Glad to help I've been going thru the same issues hope you figure it out bro.

interesting idea. i haven't really messed with rerouting things. i usually do set and forget. but i am having a range of issues....not sure i ever even sorted a single one except when my ph meter went out. i think the controller will work, but i will keep this in mind if i can't get enough heat from the light. in a month or two it the outside temp will correct this.
