Brown spots and fabric bag runoff?

I mixed up my notes and now I have no history of this plant . It's royal dwaft auto from RQS. It's in a 50/50 blend of promix yellow garden bag and dr earth black bag. I understand it's pretty impossible to diagnose without history, so that's cool if you don't comment.

But can someone PLEASE tell me how I can check the runoff ec and ph with fabric bags?!?!? It's impossible to get an accurate reading with the liquid pouring out of the side of the bag .

You can put a clean cap ch pan under it and collect the runoff, it takes very little to test for ph. What I see is potentially too much water, are you letting it dry back before watering?

It’s gotten too dry and the edges are peeling away from the fabric pot. So when you water it all rushes doen the side, won’t give h an accurate soil measurement and not hydrating the soil properly.

Next time when u pot up compress slightly the edges about an inch in from the edge to stop this happening

I had it in a plastic pot with saturated soil (bag was outside) since birth. I transplanted to the fabric bag a week ago but the spots persisted. If it is root rot, do the roots ever recover?

I'll keep this in mind. It does look dry, but the bag is pretty heavy.

If I was to hazard a guess just by pictures she looks overwatered and little burned by nutrients. Plump leaves 3d looking leaves, and drooping down.

Whats the temperature of your tent? Vpd? If you're using LEDs and your tent isn't warm enough the plant is going to have trouble transpiring, and up taking nutrients. So if you grow an auto and your environment isn't perfect, they're going to struggle at their various stages. Leaving you a small flowering plant.

THis might be the winner. I'm in an unfinished basement zone 7a/b temps from 63-73. After the stress, and then the recent transplant, I was praying it wasn't going to throw it into flower. I took that risk with transplanting so late because the soil was left out in the rain at the store and completely saturated. It was in a 3 gallon plastic pot and it stayed super heavy, it wasn't drying out at all. Suspecting root rot damage, I transplanted into the grow bag with fresh soil. I don't mess with VPD because I can't control the climate in my basement.

Is your basement closed off? How big is the basement? I'm sure you can control the basement vpd unless it's money reasons. I'd recommend just getting a big tent, and controlling that over an entire basement. Save up for it. Being able to control the environment more than none is pretty crucial when it comes to LEDs.

63-73 is simply not going to work out. Incredibly slow growth, and it struggles to transpire since the humidity is at who knows what

My guess is when an auto is stressed from the environment it's placed in, it's going to flower in a last ditch effort to pass on it's genes. So you end up with an early flowering auto that just kinda slowly dies.

I'm the king of prematurely flowering autos. Lol. My basement is 1750 sq ft. Windows that don't open. I have a dehumidifier I run in the summer that keeps it to 55-60rh. The only thing I can do is match the tent to the climate of the basement so vpd is not going to work.

I have the govee therms, last i looked rh low was 50 and high was 72 i think.

Yeah it's super slow during winter here. I usually have a good 6 months of warmer weather that I can get 2 rounds in.

A tent controller that can control an oil heater, humidifier, and dehumidifier. Get insulation boards and put them underneath the tent.

A heater will keep the tent above lung room. It's not ideal, but trying to grow plants in 63-73f won't give you very good results.

Look hungry to me. That happened to me I called it calcium deficiency and it was fixed with up potting into fresh soil on my young plants. They rode 3 weeks in Happy Frog until lowers started to crisp up the lower leaves. Light green says hungry and brown spots and lower tips crisp couples with hungry and calcium def.

To answer the first question.
Wrap the sides of the pot with cling film.

Not going to help you though, your temps are too low.

Heating underneath helps some people.
@Moflow , being some people.

I wouldn't be using LEDs in your basement.
Gonna cost you to heat that space up, I'd switch to hps, where the radiant heat would be massively beneficial.

Of course you can control the environment in a tent.
You use an extractor and slow it right down so the heat builds up.
If you still need more heat. You add it and you're heating a smaller space.

End of the day I'd just switch to hps for the cheapest solution.
The plants will happily grow at 74f instead of 80s

I like this solution! Not only do you get the radiant heat, the lower temperatures actually work in your favor.

Appreciate the help here. I like that saran wrap idea! I looked into heating methods (the ac infinity heater looks cool and it works with their controller) but the consensus was to switch to hps lights as mentioned.

Since spring is here I'll consider for next winter. Any models hps light you guys recommend?

I also just bought an adjustable height 2x4 table and put the plants up as high as possible and his helped a bit too.

Thanks all
