Nutrient deficient?

[SHOGUN420]

Hi all, this plant is on day 18 and looked to be going strong up until this point however I am noticing growth that doesn't seem right. First image shows the issue and second and third image shows different plants under the exact same conditions and feed.

Strain- velvet moon
Age- currently 18days
Light- Marshydro TS1000W hung at manufacturers recommendations at 24 inches above soil.
Nutes- just had first feed of veg using the attached schedule. I have also been top feeding with great white mycorrhiz.
Watering- I weigh my pots dry weight vs wet so I'm fairly sure I'm consistent and not over/ under watering. Watered roughly once a week or every 5 days.
Soil/ medium- Biobizz light mix.
Temperature- always between 19 to 23 degrees Celsius.
Humidity- for the 18 hour light cycle RH is 65% to 70% and during the 6hour dark cycle the RH will drop to 50% as I turn off my humidifier and slow extraction fans.

Other than that I think these girls ha e the perfect environment with CO2 bags etc, I'm at a loss to this issue, please share your experience.

Bit of overwatering, bit of nute burn. THey look good, Stay the course. I'd say dial your nute mixture back a bit at this young age and let them dry out a bit further than you think you should. CHeers, gl to you!

Good afternoon @SHOGUN420 hope your well my friend.
Welcome to 420magazine.
Very concise explanation for your question.
I don't see the ph though.
Are you setting your ph to 6.3 ?
As stated you have some minor nutrient burn , no harm done don't worry.
But she looks a little light in the first pic?
Might not be uptaking nutrients probably.
Also that schedule calls for calmag, if your using it ? It must go in your plain water first.
Wait 10 minutes add your nutrients in order full strength then set ph to 6.3.
Hope that helps.

Stay safe
Bill
