First time using cfls opinions desired

i am using cfls for the first time I have 4 23 watt 6500k bulbs in close proximity to each other about 6 inches from my 10 day old girl 6400 lumens total.
18hour days
Ph 6-6.5
Temp ranging from 65-85
Humidity 20-35%
Organic soil with triple .12% slow release nutes cut 1/3 with peat
Link to my journal https://www.rollitup.org/t/helio-ogk-grow-journal.983445/

Noticed about 4-5 days ago some slight leaf curl, still growing new set of leaves every day or two.
The advice I’d like from anyone experienced with cfls is if I’m using too much light for a 10 day old to rule that out. I’ve been raising the light to make sure it’s not heat stress, the surface leaf temp was 82 degrees at 4” away from light with room temp at 78 So it’s not heat imo raised to 6” above plant two days ago. Here is a pic any thoughts?

Stop feeding.
IMO she's way too small to feed, I grow in Hydro and don't feed my seedlings anything but water until they have their 3rd or 4th set of leaves out.

Good luck.

Plant looks fine. Don’t feed it anything.

quite feeding it, she's to small for nutes

not bad plant btw, keep us posted

Haven’t fed anything yet sorry that’s what came in the soil. Just bought a bottle of ff big bloom for added micros plan on giving half dose next Time I water. Thanks for the reply’s she is doing good just noticed the first set of leaves started curling and don’t want it to get worse. So you guys don’t think it’s too much light?

Don’t use those nutes in the next watering. Hell no!

If i'm right big bloom is for flowering, not vegging.....stay away from the nutes at this point with the soil having it already.....let that plant do what it needs to do....

just use plain water from here on out......

your lighting fine, there has been some cases the leaves will touch the bulb with no problems....

later when u go to flower just add some 2700k bulbs to your set u already have.....

Thanks guys, big bloom despite its name is just a micro enhancer the feeding schedule says to use it from week one onward. There really isn’t enough nutes to do anything for flowering with NPK ratio of 0-.5-.7, it’s mainly a supplement for grow big (veg) and tiger bloom (flowering). The organic nutes in my soil I figure is less than ffof though I can’t find any percentages of what that contains anywhere online but most people here and elsewhere say it’s pretty hot soil for young plants, so I’m just guessing more than .12% NPK that my soil had before I cut it with seed starting mix.

I agree with you both she doesn’t need feed yet, my soil isn’t formulated for canna so I thought the micros wouldn’t hurt but I’m taking your suggestions seriously.

most soils aren't made for canna anyways, just fyi....there is nutes already in that soil btw, doesn't mater if it's slow release. That's why we are saying no nutes right now....wait....just use water

Eh I’ve said no nutes. A few people have said no nutes. You got our opinions. Do what you want.

Not trying to be an ass. It is your plant.

As the choir says NO nutes

from deep Russia it comes "...NO Nutes"

1: To young

2: soil is peaty/moss will hold serious water hence serious nutes leading to serious nute burn

add 25% perlite on potup

also ensure you keep 50% of the cfl's on 2700 kelvin(warm White) to ensure correct horrmolal growth

good luck

I’m not adding nutes never said I was. I was planning on adding a micro supplement near the end of week two that contains trace amount of what I consider nutes. If I add half strength big bloom it’s adding .25% phosphorus and ..35% potassium and even much smaller doses of micros that pot plants apperently need that aren’t in my soil which the plants can use even though they are young.
With the soil I have containing <.12% NPK if I add a micro supplement I sincerely doubt that’s going to make my soil too hot.

To each there own I guess, the answer I was looking for is if I’m giving too much light to a young plant since I have no experience with cfls is why I asked here to which the only person that answered my question was budmanTX.

I appreciate everyone’s concern and thank you for your input. The fox farm feed schedule says to use it starting at week 1 in conjunction with there soil that I’m certain is hotter than mine. Most people are adding actual macro nutes at week 3 because of deficiencies. I’m not talking about adding full strength nutes to my plants I don’t know where your getting that from. All I said was I was planning on adding trace amounts of micros at a time I’m actually 1-2 weeks behind the feed schedule at half strength.

4 23w 6500k cfl's is plenty, watch for stretch that's how you adjust the bulbs up or down, i usually kept mine about 6" away from the plant, later on put 2 maybe 3 more this time 2700k bulbs and you should be good when you go to flower....you have a timer for when you go 12/12?

little lesson with cfl's growth will slow down, so take your time, this is where you learn patience with the plant......

stay with plain water and you should be good

thanks for the props......

Thank you, I am using a timer. Was planning on getting two more 4 packs of 2700k bulbs for a total of 12 while flowering should get some decent buds if she makes it that far.
Leaves are getting worse I’m battling humidity, got it up to 30% and now my walls are sweating. Can’t add any more moisture until I dry the walls and insulation so I don’t get mold, then I guess I have to cover the walls in plastic. The joys of growing outdoors in winter, I miss growing in my basement when all I needed was a dehumidifier...

Honestly i've never had that problem in the winter with RH indoors but that's me. What i do know is when it' cooler temps soil holds water in more, so watering timing gets a little jacked.....

cheep way to increase moisture if you want, take a towel wet it, and slide it in the area, you can also use a bowl of water for RH rise if you want. If your worried about mold there is a paint that you can buy that kills mold it's a primer white.....works pretty good for reflectivity i must say.....you can also use chlorine but only diluted in water and with a sponge wipe the wall.........

I would paint the walls rather than cover with plastic, things breath better that way, less chance of mould and you can see it if it happens instead of it lurking behind plastic sheet.

I had pretty good success with a throw away tin turkey pan with a couple humidifier wick filters sitting in there with water, was adding 2 liters of water a day. I have to have a space heater going as a backup supplemental heat since I’m growing in the attic of my shed, kind of a long story details are in my grow journal but it burns humidity like no other in my small space.

I don’t have any walls in there otherwise a good idea wish I could have foreseen this issue or I would have bought some plywood to put up, it wasn’t in the budget.
You do bring up a good point, whatever I do will have to be disassembled and done right after the grow if I get lucky enough to avoid mold and finish this grow and I hope to hell I never try growing in winter again unless it’s in the house which isn’t an option really.

An oil filled radiator or two might not dry the air out like a space heater.

If the time ever comes for a remodel I would reinsulate the whole space and plaster board it and possibly dry line and seal the lot. Jobs done then and no worrying about mould in hidden spaces.
Best of luck with it all.

Hello Friends, I have a quick question.
I am having a major problem with stretching use a small florucent grow bulb that came with seedling dome.

is a 450W full spectrum LED like the one in the picture good for seedlings? If so should i turn the BLUE/RED/WHITE spectrums all the way up? If these LEDs are good, how close should they be to plants? Any help would really be appreciated. Thanks!

thanks for the steal...lol

question 1: yes

question 2: 24" veg may push to 30" for a seedling....
