T5 or LED for seedlings?

[Ezdoesittz]

My babies are about 10 days old. At first I had a 4ft 8bulb T5 (I only used 3 bulbs since I only had 5 seeds) and they were doing great. Now Im wondering if that is too much lighting for them? I have an LED light as well a 300w and 1000w King Plus, although I dont think thats necessary. What is your guys opinion?

Pictures below on how they look.

Strains are Master Kush and Super Skunk from sensi seeds

Seedling does not need much light, last year I used my small Mars light for seeding

T5 works great for seedlings.

I would like to run that super skunk, have you run it before?

Just saw this! I havent grown in 10 years and back then I only had 2 harvest of OG (electricity got too expensive).

So this is my first run back at it and first time with Super Skunk. Im on day 35. Im not sure if there's a some sort of calmag deficiency or macro def but I think they should be bigger than they are now. Ill post pics in a few hours lights are off now.

I run 6, 4’ T5 HO, all the way thru, and use both the 6500 and 2700 bulbs in the fixture. Have had great success!!

for 10 days they are behind a lot. They look more like 2-3 days after popping out of soil at the most.

They look over watered. You can see the puffyness "speed bumps" in the leaves.

I didnt give them any nutes until 2 weeks. After that they took off.

What does this look like?

Ph 5.6-5.9
Ppm 620
10ml canna a&b
3ml calmag
9ml cannazyme
77-82F
55-65RH

Sorry i find its better for peeps to see a whole chart then trying to explains whats up that way youll learn to read your plants......takes a little time but find a good deficiency chart and print it off to hang in your room

T5 is obsolete.

This is by far the #1 mistake on RIU. Even a lot of the more experienced growers here will advise noobs to starve seedlings. Maybe it's because they don't want to see noobs doing better than them on the first try.

Yes this chart is all over the net lol. Calcium is immobile correct? So only older leaves. So my thought was P/k since it was lower fan leaves and also near the top. It was the only plant of 6 affected though. All my other ones are looking healtheir since I lowered ph from 6.2 to 5.6-5

This was right before lights out

They look a little on the light green side to me but all in all they dont look too bad ....

Just make sure its not an overabundance instead of a deficiency

Make small adjustments so you dont hurt them with kindness

I think its more because most noobs make the mistake of going "hmmm start seeds at 250 ppm mabey 500 ppm would make em grow FAST!"

The thing about that is they'd be right. 500ppm is at the lower end of adequate while 250ppm is deficient. This is true for ALL stages of growth, including seedlings.

250ppm is borderline starvation, even with a 0.5 scale. Try starting your plants at what you consider full strength and you will see. You're not going to burn seedlings with adequate levels of nutrition. (talking hydro here since soil should already have nutrients build right into the soil). If it won't burn adults, it's not going to burn seedlings, in fact your seedlings wish you'd do this.

I wouldnt recommend a noob go over 500ppm by i guess its a personal decision but not mine lol


I cant start mine anywhere near 500 ppm

Most ive started mine on is about 350 ppm

And when i say start i mean thats what im soaking my medium with

I also think it depends alot on the nutes your using as well

Because i have had some plants get pissed by the same ppm reading but 2 differnt nutes.
