Autoflowers day 13. Question regarding size

Greetings.

Have never grown autos before so I am not sure the size they are supposed to be at this point..

What I have are 4 Autos which are Auto BlackBerry Kush from Dutch Passion and Mamba Negra Auto from Blimburn.

I am in Coco and feeding H&G A+B just started feeding daily as they were too young to feed daily due to root structure.

I have 3 Autos in 3 Gallon Smart Pots and 1 in a 1 gallon for comparison.

From what I have seen they look small for Autoflowers.

Maybe they are still developing alot of roots and about to explode , but again I only ever grow Photos until now.

Currently have a 400W MH and temps and humidity are fine so not worried about that.
Here are the Photos

Auto BBK Day 13 in 3 Gallon



Auto BBK Day 13 in 1 Gallon


Mamba Negra Auto Day 13 3 Gallon




Once I started feeding them on day 7 from sprout they have been doing very well.

Here is a Blue Dream Photoperiod for comparison in the same tent fed the same nutrients PPM and PH of 5.8-6.0


What I am feeding currently is

Tap of 35 PPM
Silica of 50PPM
H&G 300PPM

I feed my Autos Daily starting 2 days ago and the growth has been very good.

I feed my Blue Dream and other Photos every few days due to not needing them to grow as much due to them being mother plants for a future experiment.

My conditions are fine and have grown in soil hydro and outdoor before, but never a Auto.

My only issues is that they look a bit small for 13 days from Sprout.

On the same page as my Blue Dream.

For the record all seeds came in breeder packs.

Anyone know if its either an issue which seems unlikely due to them doing fine or they are just about to explode?

As I said never grew autos before but as for my photos they are on par currently.

Also reason for using 3 gallons is because autos do not like transplant.

I do however have 1 auto in a 1 gallon for testing.

All my mother photos are in 1 gallons as well.


Any comments would be great. First Coco grow and have started to figure alot out.

Trippy

They do seem a little small and stretched for almost 2 weeks. After 2 weeks is usually when they start growing fast, same as photos. How close is your light?

I do see some nute burn too. That'll stunt a little.

Currently 10", but had them at 15" until today as they were a bit small.

What your seeing is deficiency. As I did not know you needed to feed in Coco from first true leaves. They were stunted a bit due to lack of nutrients. They are getting small doses and doing fine now, but from what I have seen most autos have leaves larger than my whole plant. Never grown them before so not sure and yes I am aware after 2 or so weeks they start to grow wild similar to Photos.

They are taking the nutrients very well.

My temps and lights are fine and I have grown before, this is just a personal grow to test out Coco and Autos.

Would you say they are going to pickup? Just wanted to know I am on the right track.

If that was just a def, they'll pick back up for sure.

Yeah they were deficient with lack of nutrients but have really been on a roll.
Will update this thread in a week.
