Seed Stockers 5 Blackberry Gum Auto's in a SCROG (COBS + Mega Crop)

[Terra Firma]

Hi everyone, this is my first ever Seed Stockers grow!
I normally grow Dutch Passion Auto's.

I'm switching over to Greenleaf Nutrients for this grow.
My tap water is pretty hard (pH8.6 and EC0.5) and contains a lot more Calcium than Magnesium. I hope that this doesn't screw up the ideal Cal:Mag ratio too much.

I'll be growing 5 Blackberry Gum Auto's in 15L Airpots filled with Atami coco coir.
I soaked a bunch of seeds in water for 24 hours before planting them yesterday.

My setup:
Space: 1.5×1.5m grow room
Medium: 100% Coco coir (Atami)
Containers: 15L Airpots
Lights: 3 DIY COB LED lights (app. 530W total draw) + 2 GrowNorthern HS1 (if required)
Nutrients: Greenleaf Nutrients: Mega Crop, Bud Explosion, Sweet Candy and Ferro: Bio Roots, Enzym Plus, pH-
Microbials: Mychorrizae spores + beneficial bacteria

Day 1
I gave all ladies a watering of EC1.0 at pH5.8. My tapwater is EC0.5.

Day 7
I gave all ladies a watering of EC1.1 (tapwater is EC0.5) at pH5.8. The seedlings are growing well. I've pulled up the smaller seedling from a pot with 2, and planted it in the furthest left top pot. It was bigger than the one in that pot, and I'm curious to see if it can handle the abuse.

Day 13.
Gave all 5 BBG plants app. 2L of nutrient solution at pH5.6. This was 5g of Mega Crop and 1.3g of Sweet Candy in 10L of tapwater. The girls are growing well and shall be topped at the 4th node on day 14 or 15.

Plant 2

Plant 3: the funky tri-leaf plant.
This one's doing some weird stuff. The main stem has split into 2 growing tops, and one of those tops is actually 2 growing tops.

Plant 5

Day 16.
The 5 BBG plants are getting 1.5 to 2L of nutrient solution at pH5.6-5.8 every day. This is 5g of Mega Crop and 1.3g of Sweet Candy in 10L of tapwater. 4 plants were topped above the 4th node on day 14, and they responded really well. Only the tri-leaf wasn't topped.

This is the tri-leaf doing some funky stuff.

Thanks for stopping by!

Day 19. My extraction fan died today, but luckily I had a smaller version that I hooked up until the other one is fixed under warranty. I think the motor capacitor died because my multimeter reads nothing. The BBGs are now getting nutrients at EC 1.6 an pH 5.6 (7g Mega Crop, 1.3g Sweet Candy and 1g Bud Explosion in 10L). One of the plants has some weird spots on her leaves. I'm not quite sure what it is. Any ideas? I've raised my main lights and switched off the small one, because the plants seem to be getting some heat stress.
