It must be in an acceptable range because nute uptake is still occurring. I used to use GH3 and experienced nute lock out a few times. When I first started using Jack's, I'd ph down to 5.8 and it'd walk up to 6.7. Always made me nervous because, for me, 6.7 using GH3 would give me problems very...

I've been doing DWC for about 3 years now. I try something a little different each time. This run, I've tried never testing or adjusting ph. I use tap water that's 8.8 ph (known from 100s of tests over the last few years). I let it dechlorinate for an hour, add Jack's 321 and let it sit for 20...

Getting a nice purple in the LSD.

Progressing.

All 4.

Had to supercrop some of the supercropped parts of the AK. I've never seen a plant do this. The other 3 are more than happy to 36" from the light. The AK keeps climbing to the point of touching it. She always droops in the afternoon. Same with the SC. States going to sleep about an hour before...

AK was out of control. I supercropped her this morning.

I've never had one stretch like the AK is doing. The LSD is starting to show her colors.

Puts out a ton of light. Hard to capture in pictures. The burple is a "1000w" Meizhi.

The tent pic above is my old configuration. Blower inside took up too much headspace. This pic is how I run now.

I don't have many pics left of the build. It was a few years back. They don't even make the boards anymore. The boards are HLG QB132's in 3500k. The PS's are Meanwell LRS350-36's. I built thee frame out of 36" angle aluminum strips that you can get from Lowes and home depot (standard length is...

LST wasn't L enough on the AK.

I'll grow AK and LSD in the same tent again, and I'll do SC and GC together, but I won't do what I'm doing on this grow again. The plant structure is too different. GC and SC are short and bushy like WW is. AK is tall and bushy, LSD is just tall.

The GC couldn't handle full strength Jack's. I had to dial her back to around 800ppm. The other 3 are at 1000ppm. I stopped adjusting pH just to see what happens. I keep reading conflicting reports about how to manage pH with Jack's. They've been sitting at 6.2-6.3 for a week now with no issues.

30 days from seed. Did a light defoliation today.

The LSD.

It may have been thrips, but I definitely had a cal/mag deficiency and some root rot going. Hit them all with a few ml of cal/mag per gallon and additional hydroguard during res change. The problem has stopped. All new growth looks great and the roots are almost all white again. Pics are the...

I'm going to do full res change outs today.

Underside.

They've all got it now. Not sure that it's thrips anymore.
