Your plants seem to be a little over fed, dark green leaves. What nutrients are you running and what are you growing in?

Are you doing anything for micronutrients?

Epsom salts for Mg?
Gypsum for Cal?
Rock dust, glacial dust, azomite etc. for complex blend to cover all the other trace minerals?

What ratios of GG have you been using and what amounts per gallon?
What is your water source and where is it coming from?
What lights are you using and what intensity?

New growth, old growth? All plants, one plant?

I have used:
GreenSand,Kelp/Bone/Blood meal, Oyster Shell
I didn't used any epsom salts and gypsum...

I have top dress at day 28 with 1 tbs/gallon 70% 4-4-4 and 30% 2-8-4. And at day 42 1 tbs/gallon 30% 4-4-4 and 70% 2-8-4.
I used tap water (ldechlorinate for 24h) I start at 6.5 ph but saw that promix is soiless so I change to 5.9-6 ph
I have the AC Infinity advanced grow tent 4x2 (LED Grow Light Board 200W)

They are at day 53 right now since they are autoflower I should be able to harvest them this week.
