I got the nutrients wrong slightly this week which resulted in some minor magnesium and calcium deficiency showing up. I'm pretty sure that's what the yellow patches, brown spots and brown tips are caused by.
The plants were all topped above the 4th node at 17 days from sprout.
hey man, def tagging along for this. gotta say someone else said this was the best first grow theyve seen id have to agree. i love your setup. personally im using the 135W HLG QB288 V2 paired with a King Plus 1000w, and the king just pales in compassion, eventually id like to add some more qbs, im running a 3000k but would like a few 4000k for veg alone. keep it up man impressive stuff!!
@FoxyLoxy, Thanks man. I go away for work for 2 or 3 days at a time and am always surprised by how well they are doing when I get home. I don't have anything to compare the QB's to but I'm pretty happy so far. They're super efficient lights and easily adjustable. I knew I wanted to do a SCrOG so it made sense to go with the QB's and spread them out so that the light is evenly distributed.
Boss, no other way to say it. Boss, you are a BOSS! I’ve never read about a setup that was so well documented as yours. If you are this fierce out the gate, I fear for the rest of us. Bravo.
@MadMama, Thanks. I did a lot of research and had it all planned out before even starting. I won't be able to blame the setup if everything turns to shit!
Hi!
I always love DIY light setup :)
I was thinking about the samsung LT-Q series, but I went for bridgelux cobs (with reflectors) for heat managment. I put the heatsink part and the power supply on the outside part of the roof of the grow room.
I sacrificed a bit of light uniformity in change for that... but is summer was a bit better.
Both have pro and cons!
I recon that 3000k was the best too ;)
You will not be disappointed with the results!
PS: Just in case you did not know: there is a limit of the number of power supply you can put on the same main house differential magnetothermal switch. You may need to check that if you want to expand.
