Are they in an enclosed space? If not the moisture will simply escape. If they were in a growbox the humidity would rise with misting as moisture would be locked in. In my opinion your baby looks pretty good. I'd relax if i were you. Your ph is not way off, most plants do fine between 6-7. Lower a bit perhaps, spesh when entering flower time. Go easy on nutes tho man - your plant will be needing them soon but go easy. Always better to start off small and then gradually increase. About watering - your plant is in a big pot but from the pictures the medium looks dry. When you pick up the pot of that size it should feel light and also be dry 3 inches down. When you water if it does not have run off it almost for sure oversaturated (unless you used rubbish soil which u havent). Dont worry - all will be fine!

I actually got humidity up a bit (its at 33% now) by soaking a towel in warm water and hanging it in the closet. It does drop when I open the door to the closet though. I was going to try and lower the PH and I got some PH down from a pet store and was going to mix a very small amount with water.
Few questions on that. I am trying to get my waters Ph to around 5.5 before I use it to get hte soil there too right? Also is testing the runoff a good way to check soil PH? I test water than the runoff and they were clearly different (7 vs 6.5). I may need to get a new water PH tester because i got cheap strips and they dont measure below 6.5. Also I was going to do it very slowly as i heard this ph down is very potent. Once i get the pH down do I need to keep using the solution or should i stop using it for a while? Also is it safe to mist the leaves with the solution with the PH down in it or should i use separate water for that? I am going to try and mist the leaves 3 times a day or so because it make a lot of sense when someone pointed out they are just drying out. Thanks.

You mean get the water to 6.5? There's no need to do that if your water is at 7.0 to begin with. You saw it yourself -- the soil buffers out that tiny bit of base and voila... 6.5 out of the bottom.
Yes, runoff is a good way to check it, but people get carried away about what this represents. It's a good yard stick -- it will tell you if you're getting "way off", but that's it. The runoff method only measures the most mobile fractions of acid vs base; there's alot more buffering that hangs on the microsurfaces of the soil that isn't measured (and this buffering is why you shouldn't stress about this factor in soil).
Don't use pH ups and downs in soil unless you have a major swing to correct. They introduce additional salts that can cause other problems. And it's just unnecessary steps and cost.
Colorimetric pH strips are good for the level of precision we need in soil. They're more reliable and consistent than cheap single-point meters, which give you a kind of "faux accuracy" (as in, yeah, the meter says 6.3 or 7.1 and it looks so precise on the output but, really, those cheap meters are so unstable it's just as likely to be way off). Colorimetry is so simple and cheap that people mistakenly write it off, but the science of it is very tight. Get a bottle of strips for the 5 to 8 pH range for $3 or so - it's good enough.
Some people misinterpret my advice on pH as "Kriegs thinks pH doesn't matter". Nothing could be further from the truth. It matters big-time. Cool thing is that, for so so many reasons, soil manages this factor for us, so all this other stuff (meters, ups and downs, tweaking our water by 0.2 points, etc) is just simply unnecessary.
Check your runoff pH with 5 to 8 paper strips once a week. If you turn up a 5.0 or something some day, PM me and we'll figure it out. As long as you have good soil (you do) and follow basic sense on amounts and concentrations of nutrients, I bet pH will never be an issue.
If your run off is 6.5 your ph is fine. When you water get your ph to around 6, but 6.5 is fine too. My tap water is ph 8.0, so to give you an idea of how little you need to get it right - 1.5 litres needs 6 drops of ph down to get ph to 6.0. Measure in drops. It would be real easy to make a little enclosure out of cardboard lined with mylar, but your plant will still do fine where it is. You can mist your leaves with either water, phed or tap. How big do you intend on getting this baby?

Thanks i know 6.5 sounds good but for my specific strain (big bang Green house) its supposed to be around 5.5. Sadly my ph strips i bough don't even go that low so I was thinking of just trying one drop of ph down to a half liter or water when i feed it. Other people who grew the strain said 5.5 was best and so did the manufactorer. If my water was 7, i was just wondering how low 1 drop of ph down usually brings 1/2 a liter since my strips suck and wont go that low.

That may be but i read from other people growing big bang in soil that 5.5 was best and the guys at greenhouse have a youtube video showing a massive big bang grow and they said the PH was 5.5.

There's nothing special about the botany of big bang, I assure you. Did the GHS actually show such a 5.5 measurement in a side-by-side comparison trial with big bang run at 6.5? Didn't think so..
Marketing hype.. sheesh....

You asked earlier about nutes for flowering. I recommend going on ebay & getting yourself flowerpower from blue mountain organics. Their bloom fertilizer in the ffof will be a wonderful thing for your girl once you get your probs taken care of.

Updates pictures from today. The yellow on a few of the leaves isn't going away but it doesn't seem to be getting worse either.
Added 1 drop of Ph Down to last .5 Liter of water i gave it which I tried to spread around more especially the outer part of the pot. Also have been misting the leaves a few times a day and now have two wet towels having in my closet and the humidity is between 30-40%.

That is a good to hear. From checking pictures over time it seems to be still getting bigger and the new parts look green and healthy. Ill just keep what I am doing for now I guess.

New Problem anyone have any ideas?
I noticed one of the leaves has some light green spots on it. I don't see any new yellow but I dont know what is going on with this leaf.

I tried giving it more water. I was giving it .5-.75 L and had been since day one and the problems looked like lack of Nutrients (specifically Nitrogen). Since my soil (fox farm ocean forest) should have plenty i figured id give it more water because i had been watering it with that amount since it was 4 leaves and now its much bigger so it should need more water to get more nutes from the soil.
I also tried moving the lights a little farther away because it was growing within an inch of them so now its 2-3 inches.
I am still getting a few yellow spots on some fan leaves and just got my first brown tips on some of the new leaves on the top.
Anyone have any ideas??? I want no more leaves to turn yellow/brown but its not working out.
The pics aren't great because I just sprayed it so the water is messing up the light, but the biggest leaf on top in the center has 2 yellowish/brown tips. Also A LOT of the new leaves have the very smallest brown tip at the end point of the leaf where as that big one is on the side, they are all on the end. Even some of the babies.

Sorry to quote myself, but the point of all of that is, that this seems to be the reason the problems are not getting any better. Poor watering technique, and not allowing to completely dry. Deep roots sit in soggy soil and suffocate, get stressed and stop uptaking nutrients. Nitrogen is the first to get the chop...then in a domino affect, other nutrients get locked out as the plant begins to stress.
There is a tendency for growers to look to nutrients and additives to fix this problem. There is no additive or further nutrient your plants need that you are not already giving them or are already available in the soil.
All cannabis hates it when their roots are soaking in the combination of both soggy AND oxygenless environments, this goes for deep water culture (DWC) through to soil. This is why in DWC, growers put in air stones to allow plants roots to breath air.
What they need more than anything is a change in watering method that involves thorough watering and thorough drying of soil.
I don't write this as a good idea that one can impliment sometime in the future, it IS the fix to your plant problems to slow and prevent further deficiencies in what is otherwise a healthy plant.

Thanks Jonus. How long do you recommend letting the soil dry? I just did a larger water (1.5 L) but even with that much there is no runoff. WHen I check the soil I put my finger a few inches deep and see if its dry and usually that is every 2 days. Should I wait maybe 4-5 days before watering again so the deep soil can dry? Also I have been misting the leaves regurally. Should I Stop that too?
