Slow Growth?

[EzPz]

I have 8 plants 11 weeks old (germination time included) all from seed. I fear my flowering start time May be delayed. I planned on starting 12/12 the end of August. I think they are to small though.

Setup

• 4x4x8 tent
• 1200w full spectrum LED
• 8 plants in tent
• Soil medium
• 3.5g fabric pots

Ideas or thought?
Pic 1) 3 weeks
Pic 2) 11 weeks

They do look slow growing for 11 weeks. I would have said 2-4 weeks old for those in the 2nd picture. Size and overall growth is controlled by light, pot size, type of medium or soil along with air circulation, temp, ph, humidity and nutrient levels. Not to mention genetics. If one or more of these is out the grow can be slower.
I would get them to the desired size and then do the switch to 12/12. How big the plants should be depends on the room you have above them for the flowering stretch and distance they need to be from the light.
Good luck with the grow.

1200w full spectrum LED.....
What's the brand & model #?
I have 2 of those 1000w full spectrum blurples. They are actually 150w from the wall light fixtures. That could be part of the reason they aren't growing.

What kind of bug are you battling? I see a lot of white powder dusted around your tent...how much and how often are you watering?

They look a little stunted but I'm not very familiar with scrogging. Once you turn to flower you should see a big stretch. Especially if you have infrared capabilities.

Your lights seem pretty far away. Buy a lux meter.

Any idea on what I could give them for the next month while they are growing to boost foliage/yield?

Carboload from advanced nutrients is a good supplement for exactly what you're looking for.

Might be worth checking the "nightime" temps, when the lights are out. Low temps can slow growth.

I checked temp at night it drops about 4-7 degrees.
i just added blood meal per a hydro store advise.
1 of my plants are starting to wilt at the tops.
any idea why?

[homegrown]

are you feeding anything other than blood meal?

homegrown I used some azomite it’s just what I had on hand and have used in the past.

What is all the white stuff on the leaves ???
did you do any kind of training technique on them ? Topped ? Or what ? Or just letting them grow ?

im a soil Grower, always have been and always will be.
and what type of soil are you using? and how much nutrients have you been giving them ? It could easily stun the whole grow, if they get nutrients they don’t need..

I LST then from the beginning.
Used super soil to start and then added Dr Jimz.
I do know I was under watering them for a few weeks.
fabric pots wick moisture away super fast.
The white stuff is DE I had some insect issues around week 4.

I topped them early on and more recently.

I used to be a soil grower then I switched to DWC.
this is my last grow using soil. I am a outdoor grower.
