Brown and curling leaves

How many lumens are best at the leaf? I use 50 W CFL, two 20w LEDs and. 60w LED spot light all at 12 inches with a fan in a 3 x 3 (4 pots) space on 18/6
with a phone app light meter I’m getting 350 lumens at the leaf (seedlings) this newbie appreciates opinions.
 
Led need to be a little higher then CFL from your plants. CFLs can be with a couple inchs while LEDs need a foot or so. You will also need a par meter not a lux meter to check LED efficiency so your phone app is probably not picking it up.
Once your plants have a couple sets of leaves 30,000 Lux is the number you're looking for Optimum veg growth and 70000 to 80000 Lux for flowering have been at the top of what a cannabis plant can take,.
A general rule of thumb with CFLs, HID, and actual draw Watts from the wall LED is 40 to 50 watts per square foot.
for example I use 180 watts of cfls for seedlings in young veg in a 2 x 2 area.

and a 600 watt HPS in a 3 by 4 area. The more watts you get the happier your plants will be.
good luck and happy growing
 
Fish emulsions are a good choice for fertilizer however I can't advise you on the dosage and frequency. Have you check your local Walmart for Alaska fish fertilizer and the Earth Juice line? Good Liquid Fertilizer readily available, my hydro store sells Earth Juice for twice the price.
 
My new plants are just a week old and doing well. I will dose one on a dilution of 2 table spoons per gallon of fish emulsion per gallon. I downloaded a LUZ app and
my 100 LED flood light, two 20 watt LEDs and 100 watt CFL all set at 8 inches plus a small computer fan, are doing the trick. Plenty of light Opinions always appreciated.
 
D.A.A.S: I have tried to order from New 420 Seeds....what a royal pain in the ass.. emails and site NOT REGISTERED PER GOOGLE!
There was no click to place (click) an order. A very frustrating site. My emails to them were all returned! What’s up with this?
Do you have an email address for them?
 
Called Paul, hopefully things are straightened out. Will let you know. Also, have you tried cow manure. I started using a combo of black yard dirt, sand, fireplace ash and cow manure for my ornamental plants. It gave them a boost in only a few days. Thinking about starting a few “special” plants with it. Will start the seeds in wet paper towel/dark closet. Opinions?
 
I would research that a bit more. I pay $30 Canadian for Promix HP soil - easy to use. HP stands for high porosity - which means it has lots of perlite. That's something you should add - perlite or some other buffer. Allows the roots to breathe.
 
Everything out with 420 seeds. As it turned out, I was using an iPod and didn’t scroll down. Just call dumb! Paul fixed everything and I received my order within 10 days!
 
Adding diced bananas, egg shells and coffee grounds to my recipe soil. (Black dirt, fireplace ash, sand, fish emulsion and cow manure). My ornament plants are happy!
will give my special plants light doses of this to see how they accept the push!
 
Mr Furley, my light recipe; on 100w cfl at 4 inches, one 50w cfl at four inches and thinking about replacing it with another 100w cfl, 80w led and thinking about adding another. And two 30w LEDs on flex stalks. Also a four inch Computer fan and the set up is easily raised and adjustable as theplants grow. Thinking this will give me a wide variety of spectrum production. What do you think?
 
Definitely, cannabis loves a blue Spectrum for vegetation and a lot of red for flowering. They make Brite white and daylight CFL, both have a different Luminary rating. Daylight is more Blue with the bright white more red.
If you can get 40watts to a square foot you will be good.
Thanks for the update and happy growing.
 
Thinking about switching to 3 gallon fabric pots. Thinking the dirt in the bottom of my 3 gallon plastic pots stays too wet....opinions please
