Blue Dream'matic Auto in 3x3 Gorilla Shorty - Hydro Attic Grow w/ Photon Fantom WaVy Board LEDs

What's up blades, here we go onto grow #2! This time using a Blue Dream'matic Auto seed acquired from a Comparative Grow thread hosted by The Vault. This will be my first time growing an auto, and I will be using the same setup that I used for my last grow, link to that journal in my sig.

This seed was germinated on 8/20 and planted on 8/23. pH at ~6.2 and ppm starting off in the 400-500 range. Now for pics!

Day 1-


Day 11-


Day 15-
Little bit of yellowing appearing on the lower leaves between the veins, signs pointing to Mag deficiency so I added a few mLs of some BluePlanet CalMag with Iron.


Day 19-
A little bit more yellowing but the newer growth seems to be looking pretty healthy

pH is staying right at 6.3ish, ppm staying steady around 450. Anyone have thoughts on the yellowing, or does it look fine?

 

It's essentially a weaker version of the Lucas formula (4ml of FloraMBloom and 2ml of FloraMicro) with a few mLs of Rapid Start, 2ml of FloraBlend and 1ml of Root Exceleratur. The water I'm starting with is a ppm of 22 and pH of about 6.9.

EDIT: Forgot some new stuff, I also added 4ml of silicon and 4ml of CalMag with Iron.
