How are my autoflower plants doing? I’m a little worried lol

[Ak96]

Ok so here is the lowdown.
Both Autoflowers under a Mars Hydro300w.
Temp and Humidity is at 73F and 50%.

Left plant (Auto Pink Kush) is mid week 3 and still in veg.
Right plant (Auto Alaskan Purple) is just starting week 4 and starting to see the white hairs indicating the beginning of flowering.

I started giving external nutes around 5-7 days ago (BioGrow) and about to start to add BioBloom today.

They look healthy to me.
The thing is, the plants look super small! They are both only 6-8inches in height. Is this normal? Will they get taller?

To me, they look right on schedule. Keep up the good work!

How tall do they roughly grow? I was expecting them to get most of their heigh during veg.
Using hardly any of the tent space haha

The largest growth spurt is during the first 2-3 weeks of flower.

Going to depend on strain and grow environment. Expect each plant to at least double in size during the flowering stretch!

It looks like you may be giving them too much nitrogen. Pictures with lights off and camera flash only are best. Good luck.

As mentioned, it all depends on the genetics and the environment. If it won't grow upwards, you can always spread it out. It's a little late for your Alaskan Purple but you can always LST the other and make the most of the fact that it wants to stay relatively short. You can still LST the AP but it gets a little trickier once the stems start getting thicker. Just try to create as little stress as possible and you should be all set. Also, check out others that are growing what your growing at growdiaries.com. It's always nice to see how other people's plants grow compared to yours. Good luck!

I’ve actually used LST for the last 10 or so days on the Alaskan Purple. Everything seems fine to me, as far as branch placement is concerned

You shouldn't have any issues continuing to LST through the flower stretch.

Looking good dude! Im nearing the end of my first auto grow and I was having the same concerns at that stage as well. They'll definitely grow more! And ya you can keep LSTing them for few more weeks until the main stems start to harden up and the stretch slows down.

Looking on point, 1 on left has too much nitrogen hence the tips of leaves clawing

How would I go about reducing that?
It might be in the pre-made soil as I’ve only given it nutes 2/3 times

Reduce feeding amount. Are you feeding at full strength according to the manufacturer?

Could be a mix of the soil, if it has nutrients, and the nutrients you introduced to them. Can't change the soil regardless, so your only option is to reduce the amount of nutrients fed to the plants.
