I could really use some help, Plants like paper and deforming. Oh boy.

[FunkyShot]

Alright, Things to note. I have no idea what I am doing as this is my very first grow. Messed up a few<probably alot>things and thought I've fixed all the issues and just want someone else's input that knows what there doing. I sure don't. Any help is truly appreciated.

Room temp stays at 74 with 45rh in the day and 65 at night with 60rh.

Plants feel like paper or sandpaper, I could simply snap the leaves if I wanted to. The newer leaves are less paper but seem like they are going to go a similar direction. Brown spots. White tips. Yellowing.

I used miracle grow potting mix with time released nitrogen for the first 3 weeks of there life. <I fucked up>

I transplanted them into a more correct dirt mixture. Mix of fox farms and local topsoil bag and perlite.

I thought they may have needed more light, Had them at 8000 lux moved to 13000. Did not seem to help infact made it worse. Moved it make to around 8000

If you’re going to use miracle grow, you want to use moisture control (the blue bag).

Looks like you may have a calcium deficiency, but hard to tell with your lights.

Can you use a regular light or the flash on your phone to take pics? It’s impossible to see all that’s going on under blurple.

First fill the pot to top if you can, the closer to top the better.
Turn your light down even more and lets discuss your watering habit.
Also what nutes if any you have used.
The pot has drainage holes in bottom right?

No nutes yet. I was unsure that adding more wouldn't just kill them combined with the miracle grow. I have the fox farm trio as well as a cal-mag mix coming in the mail today. All have large holes at the bottom. I water them when they "feel light" Or when I stick my finger in a bit and its dry. Ive used 5 gallons of water since the start. Its roughly week 4 but there has been little to no growth the last week.

curling up makes me think a nitrogen def or too much lightning, maybe both

If you can get a $10 moisture meter it will help you figure out proper water IMO.
I use this method;

New Simplified Way to Water Marijuana Plants

To know if you need to water your cannabis plant get yourself a soil meter. Poke or drill 4 holes in your pot 1/4 way up from the bottom spaced around the pot...

www.thcfarmer.com

I drill holes in my pots 1/4, 1/2, and 3/4 up the pot on two sides so I can thoroughly check.
It gets easier or the plant is more tolerant when older, while young proper watering is key.
Turn your lights down as mentioned or move them up and add half dose of ferts when they arrive.

I've considered drilling a few on the side when I was first drilling. Now the lights I have two settings one is a bluer light the other reddish. Following the instructions I was told to turn the red on around this week. Do you think it is possible they were not ready for the switch? The information I read on this said around week 4 so I've done it. Some issue got worse after this but were already starting to happen under just the veg switch so I kept it. In hindsight it seems like my light intensity may have been also an issue.

Also Thank you to everyone that is helping, Honestly I did not think anyone would reach out!

FunkyShot,

You didn’t screw up. In fact you fixed the issue. The leaf necrosis is confined to the oldest leaves. The new growth looks pretty good. Leave them attached until they really dry/ die out. They are still making stuff and plants are tiny.

When you say the petioles easily snap that’s in line with elusive suggesting maybe a calcium deficiency.

Like the guys suggest fill the pots. More soil medium - more roots.

Zill.

Thank for the tips, Well see what happens now. Luck will be needed!

Thanks man, this is quite the confidence booster. I was hoping the new leaves were doing fine, I thought the tips were turning a little white because of the light so moving that up more hopefully will solve that issue in the future.

I have no experience with 'blurple lights' but believe they say red for veg , blue for flower ?
I would run both the whole time personally and be looking at full spectrum lights.
That being said whenever you switch lighting or soil you may note a week of pouting from the plant.
The new growth does look good which is why I said 1/2 dose of ferts when they arrive.
I use the fox farms but skip the Tiger bloom and use their dry3 for flower. Read more than a few horror stories after people added the Tiger bloom?
I also use their wholly mackerel in veg with kelp from Coast of Maine during the grow.

Those tips, meristems are growing quickly. Sometimes faster than the plant can supply nutrients. Things will catch up. All good.

Never fill buckets part ways it will likely give an undesirable water table. Read here for understanding.

your humidity is an issue if anything it should be higher during the day and lower at night. you want about 65% light on. Read here for understanding of importance.

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

your light is a blurple use both red and blue switches on and adjust to the desired intensity. You have WAAAAY TO MUCH LIGHT. Lux measures mostly green spectrum and cannot be used as a crossover for full soectrum LED with white. I CANT STRESS THIS ENOUGH. Your ppfd should be around 150 on those plants right now At 8000 lux under just blue you are at 950ppfd thats as much as a full grow plant can handle in flower under 12/12 and is you LARGEST issue right now.

turn both switches on red and blue and do the following

use this link and select red + blue LED as the source. You will see you want no more than 2000 lux for this stage

And those plants have no air flow positioned like that in these buckets

Wow, Thank you for the extremely, extremely helpful tips. Thanks to an earlier post I moved the lights way further away, According to the number you just gave me and that handy calculator I have them right at about 160 ppfd right now. The dirt is like that honestly because I had 4 buckets and just a bit short on the dirt. I can get more but should I let the plants grow a-bit more before moving them or would it be best to just pick up half the dirt and fill in under the plant? As for air there is a fan on the top angled diagonally on all the plants but I see what you mean, Nothing On the sides or bottoms are probably going to get decent airflow. Thank you!

Thank you so much for the help. I think with all of the tips and help so far I might manage to get these babies back in shape! Or at least I feel more confident I can!
