bb bliss, Thc bomb, sour diesel autos

Hi, I'm on day 16 with my first auto grow. 3 plants
Blueberry bliss, sour diesel, and Thc bomb, in a 4x4x6 tent. Running a 400w mh light up high a 300w led lower and 2 T5 light's about 2 inches from the top of the plants. I used happy frog mixed 70/30 with perilit in 3 gallon smart pots.
I haven't added any nutes other than what was already in the HF soil. I have been watering lightly with ph 6.5 water. The lights stay on 24/7.
Think I should start with really light nutes yet?
"Big bloom" is what I have.
Do they look the right size for 16 days from seed.?
Do you think an oz per plant is over shooting it in the conditions I have?
I have another 300w led I could run. Should i? Would it help or hurt? . Temps run 71/85 degree and Rh runs 30 to 50 percent. I know this is low but I have had a hard time getting this number up. I leave a lil water in a dish and spray the topsoil everyday to help out. Anyway any help will be much appreciated.

Nice! They look a month old to me. Good job, I always have a hell of a time with those damn seedlings!! I wouldn't use big bloom yet, you should use a grow formula until you switch to 12/12. Looks good, easy on the nutes unless you see some yellowing or spotting.

Nice little beauty's bro, one Question what type of Florencent light is that pink one you have...

I think your talking about the T5. It's just the glow from the led panel making it look pink

Thanks I have been really stressing, trying to do everything correct. It's good to hear a complement

Kind of depends on the strain as to how fast they grow... The pic below is a Northern Lights auto at day 18.

Edit.. Sorry, I just saw that you stated you were 16 days from seed not from sprout. If we are measuring time from seed that NL would have been 20 days.

As far as nutes.. The soil you are using has plenty of nutes to last you through 3 weeks minimum. That NL was not fed anything but pH'd RO until 22 days from the sprout breaking the soil. Autos (as I'm sure you've read already) are crazy sensitive to over feeding. I'd wait until about the 3 week mark since sprouting and give it a 1/4 strength feed. Just my 2 cents.

yeah, strain dependant on growth. Here is my critical rapido at 20 something days old. You can check my thread. It's the 2 plants in the back.

also... expect a huge growth spurt very soon. Autos are really fun to watch between like day 15 and day 30.

Someday I'll have big leaves like that @ 16 days! I'm lucky if they live! I suck at seedlings!
