Auto Plants Growing Too Slow?

[Flashindustry]

Hi guys,

Apologies if this is not the spot to post this. New to this forum and growing and just had some concerns if I might be doing something wrong and was hoping for some advice, as my plants look smaller when compared to grow journals of the same strains and my plant is showing signs of early flowering. Current setup:
Seeds: Crystal Meth Auto by Fastbuds
Space: 1m x 1m x 2m Grow tent
Light: Sunraise 1000w LED (Not ideal i know, will upgrade soon) Keeping light distance at about 80cm.
Medium: Coco/Perlite 50/50
Nutes: EHG

So far i have been feeding the plant mostly mineral water, with minimal levels of nutes every 2nd watering. Its been 4 weeks and my plant looks small and is showing the first pistils already.

Please see pictures. Should i be concerned? Any changes i should be making?

I can't really tell from the picture but sure they are pistols and not new growth?

Quite sure, wispy white hairs popping out. I will try to take better pictures.

Looking surprisingly healthy for a small 4 week plant.
I think I would lower the light to about 55cm and start giving it a bit more nutrients.
Since it's an autoflower and already starting to preflower then it is what it is.

Let's see

How often do u water? Coco needs water and 1/4 strength nutes daily

Most LED lights run at 24" above the plants, I'd drop it down a bit

I have been watering daily, but only around the base of the plant. At first I was ensuring the entire pot was moist daily with out any run off, but ended up with over-watering symptoms.

But yeah, will drop the light and up the nutes.

Water till runnoff...Coco retains no nutes, so good watering is needed

It's not soil, it can't be over watered

Water the whole pot daily and use some Yucca extract in the water.
1/4 strength nutrients.

If you have hydrophobic dry spots in the coco it will stunt your root growth.
