Just asking about the lights because I personally had problems with them.
Really hard to see with the purple light.
Can you provide pics without them?
Looks like a deficiency but hard to tell.
Someone else mentioned lockout.
What nutes do you use?
Do you supplement Epsom salts for Mg?
I'll have to take another look at my spectrum and make sure it lines up with what the peppers need.
I used epsom off and on in my outdoor peppers, but never really saw a difference. I use GH MaxiGrow and switch to a 1/2 MaxiGrow 1/2 MaxiBloom mixture when the fruits arrive. I would assume the lockout problem would be fixed with a full water exchange.
Just to add some info, for my 25 gallon res I use 40 grams of 4-18-38 hydro fertilizer, 2 TBS each of Epsom and calcium nitrate (15-0-0).
This gives me about 750 ppm and I scale accordingly for what I'm growing. I've been doing this consistently for about 3 years and grow ten foot plants. That's how I learned about indeterminate tomatoes. Lol
I believe peppers like 800-1100 ppm.
I'd love for you to solve this... Learning for everyone. Hydro is awesome!
Will definitely throw in some epsom, to cover all my bases. I've heard the peps like the high PPM too, but am currently aiming to come back down to 600-800 for relatively mature plants. I don't have any rationale for it, just think I'm locking something out at 1000-1200 PPM. If they spruce up after a certain change, I'll throw it on here.
In aeroponics, I keep nutrient concentration between 400 and 600 ppm, Ph 6.5. This has worked for years.
Post fotos with normal light; the purple light is not helpful.
I don't know enough about the differences in Aero vs Hydro DWC for nutrients PPM. This is making me think I've got to read a textbook somewhere. I know everyone has their own magical KoolAid. Will throw on some photos of the problematic batch.
I have a tiny bit of experience with aerogarden peppers and no experience with hydro, but what I can say is, What starts in the Aerogarden, stays in the Aerogarden. I've had no good results starting seeds in an Aero and then transplanting them to dirt. I don't know if that translates to hydro or not but it might.
I've got to say I've had outstanding results transplanting herbs and tomatoes from my Aerogarden to both soil and to my own hydroponics setup... those tomatoes will grow like weeds. But the proprietary Aerogarden nutes are phenomenal.
Depends. HID lights don't have to be close to the plants, they're like a little sun.
So you can grow seedlings to mature plants and every stage in between.
I grew 16 5-gallon buckets under one bulb. Grew lots of food for my family for less than a dollar a day.
But that was 3 years ago. If LED panels have progressed I would definitely like to look into them.
In a grid-down situation with solar panels (yep, I'm one of those) watts count!
The LED panel I bough starting out was too bright to look at, but the actual lumens spec was terrible. It was a fellow hydro guy that looked up the specs and drew it to my attention.
But anyway, if lights aren't the issue I hope we get your problem solved.
Your plants look crispy.
I've definitely got a long way to go learning about my own LED setup. I thought I crunched all the numbers initially, but I'll take another look
Here are the lights-off photos, new growth is really starting to look like hell; fruits are falling off.
