If you can some times I toss water on my floor to up the RH. Just put a fan blowing on the water. This may take a bit of water. Some times I have thrown down 12 to 15 gallons for my rooms.

Hi mate.
Man sucks about the girls, but I am sure they will bounce around. Are you running all the lamps at the moment? I'd be tempted to turn some off, somehow at below 70% (unless we're talking sub 40%) RH I don't think the issue is related to that, just based on my own observations. I think I read you'd dropped the light hours to compensate already.. but it might still be worth it to see if they come round.

Hey, Timmur, no worries, they're still young enough to bounce back. Imho, DWC pH should be closer to the lower limit of 5.5-5.8. Some folks let the pH rise to 6.2 end of flower. DWC is like walking a balance beam; gotta get relaxed about minor pH swings due to plants sucking nutrients (pH rises) or sucking more water than nutes (pH drops). After a while you'll find the center of the beam, where the plants are drinking and ppm and therefore pH stay pretty constant, and you'll feel fine on it. I grow also in 10% humidity on sunny days with little visible problems. In flower tent they can get up to 40% rh. Anyhoo, I like this kind of thread where you see every tiny consideration that goes into growing much better than the "hey guys, I just harvested this. Whaddayasay?" Good day to youse. Dwd

Ive been lurking the thread for a while and I'm stoked to see it up and running... and I'll now throw my 2 cents in....I think if you dropped the ph down to 5.8 ish you'd see all of your issues clear up. The funny leaves as well as the deficiency. In my experience, the ph in my reserviors always climbed somewhat as time progresses. Starting the ph at 5.6 and letting it climb to 6.3 or so always kept things happy.
So first, thanks for the advice! I've kept the pH high based on Current Culture's recommendation. I've let the pH drift down to 5.8 as of today, so we'll see how they like it. Here's what they look like today. Sorry the pics are so crappy.
Veg & Bloom @ 250 ppm.
Yeah I backed off to about 1/2 of the lights (350 PPFD) until they started to come around and then I bumped up to 600 PPFD. They seem to be liking it.
Humidity is finally getting where it needs to be. I'll give wicking a try if I need it.
Are you still planning on mainlining?

They are totally starting to look healthier, keep on doing what you're doing mate they'll be flying in no time
I'm not sure. I have 5 plants that are really growing now and 4 that are a bit stunted and/or younger due to germination issues. I've been considering just air layering the 4 or 5 vigorous/larger plants and grow out clones. It'll set me back and reduce selection, but I'd have a situation closer to a monocrop. I could still mainline them after, but I'm not sure how well it works with clones. Hmmmm?
Been scratching my head over the magnesium deficiency and I have an idea what might have happened. The O2 levels have been super saturated the whole time. Maybe the metals are oxidizing?
I'm almost certain that I'll transfer them to the UC this weekend. The roots are crazy now.
They say small clones that are taken before the leaves start alternating can still be mainlined easily. Once they start alternating either before cloning or after cloning they can still be mainlined but it is harder to do.
What EC are you running? v+b, correct?
V & B correct. Running .4 EC or about 250 PPM (700 scale).
.4 is extremely weak IMO. I tend to start seeds and cuts at ~1.0EC...YMMV. One thing I can tell you about v+b: if your feed is too low, you plants will manifest all sorts of weird/contradictory symptoms. I honestly think your feed is too low...try bumping it up to 1.0, it won't burn them. I need to feed the SB at least 1.4 once it's well rooted, and can go to 2.0 in mid/late flower. I've also noticed that under cmh they take more food vs hps.
Alright I'll try it. I was keeping it low because the dissolved O2 was so high that I thought they would burn. Thanks.
