Dutch Passion CBD Kush & Blueberry Scrog under a GN Rebel

[dirty budster]

I just started my 4th grow. I'm doing a photo run this time as I really want to try out a high CBD variety. I chose the DP CBD Kush so I will be growing 3 of those and 1 DP Blueberry. I really like the auto version of the Blueberry so I'm curious to try the photo.

SETUP
The setup will be as follows:
Tent: 60x60x120cm (2x2x4 ft) Homebox XS
Fan: TD silent 280/380m3/h running at 150V
Filter: Carbon active 300m3/h
Light: GN MS0006 with 6 rebel modules.
Soil: Plagron grow-mix in 6.5L square pots + 2 tbsp of dolomite lime per pot and ~30% perlite
Nutrients: Canna rhizotonic root stimulator, TNT complex(veg), bloom complex and phosphorus plus
SCROG net with 5cm squares

I put the seeds in a glass of water for 24 hours and then directly into the 6.5l pots. A couple of days later the 3 CBD Kush popped up and the Blueberry popped 2 days later. The CBD Kush seedlings were really tiny, I had to switch to manual focus to get a clear picture of them.
Right now I'm trying to figure out the right height for the light. I'm currently running two modules and the light is 50 cm away from the tops. At the moment I'm running 24/0. If anyone has experience starting plants under the rebel modules I would be happy to hear about it.

Day 1

CBD Kush just popped.

Day 3 (day 1 for the blueberry)

The same kush plant 2 days later

Day 5

They're looking a bit stretchy, especially the blueberry in the upper right corner, so I lowered the light to 45 cm.

Day 9

I think I might have run into a bit of trouble already. CBD1, lower left corner, is looking a bit pale. The leaves are a lime green/yellowish color. I'm not sure what the reason could be. I made a soil slurry and that was around pH6.8, which doesn't seem too bad. I also raised the light to 55cm in case it was too intense. I will keep it there until I see some signs of recovery. It looks a bit like a nitrogen deficiency. Anyway, I gave them a foliar feed with rhizotonic to see if that helps. I also watered them with rhizotonic at pH6.4 as the top few cm of soil was dry. I gave each plant 250ml so that they don't take too long to dry out again.

I snapped a couple of pictures to show what I mean, hopefully you can see them.

There is some light brown spotting at the leaf tips as well.

Day 10

I snapped some pics of the leaves of CBD1, although I'm not able to see them at the moment. It's gotten a bit worse since yesterday.

I was thinking, since I started having these problems after switching to LED, maybe I've been running the light too close so I raised the light to 68 cm and switched over to 18/6 to see if that helps them turn green again. It's only a bit odd that they stretched when the light was at 50cm. The blueberry grew from 6 to 8 cm in a day, which lead me to believe that the light was too far away. I also thought that 50cm with 60W of LED would be a safe distance, now I'm not so sure.
I also added some cal-mag, in addition to the rhizotonic, to the foliar feed and spray them with that at lights out.
