Hmmm, thanx for the reply Krip, I'z gots one of those expensive PH meters from back in the day when I grew organic. But I have let it dry out (a 60$ replacement) as I have not needed it for DBHB. Or at least I thought I didnt need it.
DBHB soil should control the PH if I understand Doc's instructions correctly (and I might not....apparently my schedule is a bit weird)
I do add the occasional Blood Meal and Epsom Salts.
The only time I measure PH these days is when I take clones or soak seeds, and I just use PH paper.

The schedule confuses me because I don't know how much you're adding per gallon, etc.
Your temps are high and your humidity is low. That's why your tops are getting crispy. 84 with 45 humidity and a wind blowing over the tops will make them look like that every time.
Get the humidity upwards of 60% when temps are high. 65% humidity and 85 degrees is a good match.

Ph isn't an issue. Don't chase that rabbit down the hole.
I have to defer to the high brix soil Doc on this one! Us hydro guys are always thinking it's a PH problem (in hydro, it usually is!)!

Yep. Hydro is a different thing and pH is muy importante.

It's such a weird thing that mid to high 80s can be dangerous in an indoor grow 
Hey Doc I have been reading some of your older journals and stumbled upon the fact that you had been using a swamp cooler to help with humidity in your grow space. My humidity is usually on the low side and I feel things suffer because of it. So to the point I have started looking into getting one but they all seem to want an open door or window in order to work right which isn't really an option in a tent. Do you think one would work in a tent if it sat in front of the in take? Are you able to set them to run til a certain rh is achieved or would I need a controller? And I see it mentioned that they need to be filled as often as every 4 hours, was that the case in your experience? Thanks for reading and I hope you or another can give me some insight on this.

Without C02 and with low humidity and wind across the tops constantly....yep. It does that.
I don't know if I've ever mentioned it before, but I think the environment is the most important aspect of successful growing.

I used a large swamp cooler at one time. It didn't need to be near an intake or anything like that, it was just water dripping over a straw mat with a fan blowing the evaporating, cooling, humid air out. It dropped temps AND increased humidity and worked really well.
Except the straw mat grew mold. Big problem. I bleached and peroxided and that helped, but then the straw mat deteriorated and pretty soon I found myself using a good old humidifier.
The swamp cooler worked better, but it ended up being a problem.

I think that delicate balance is the same thing that got me 2 rounds ago Doc. Last round I kept my humidity about 10% higher than before (mid-high 60's most of the time) and the lights just a couple inches higher on average, and didn't have the crispy upper fans. I bet that is the ticket for me.
I'll definitely keep an eye on it and considering I just dunked a few beans, I'll have the perfect opportunity to check it out. I have a small cool-mist humidifier that I turn on when it gets below 50%, but it really only moves it a few %...but it helps.

When temps get high, stomata begin to close. They close especially fast when things are hot AND dry.
The upper leaves will shut down, but the lower leaves will continue to work. There are some sativa's that love to run at 85 degrees, but they'll also want 70% rH at the same time. rH of 45% with that same 85 degrees will toast 'em.
Keep rH between 50 and 60% and generally speaking we're in good shape. If you have the ability, small changes in temps and rH can produce different traits in the plants.
You might have noticed, for example, that plants directly under the lights have more sativa traits expressed, while the same clones in the corners express slightly more Indica traits. Has to do with the position of the lights.
Temps, humidity do similar things.
Do you have a humidifier you recommend? I'm really considering the swamp cooler route but if it'll become an issue I don't wanna spend the $200 on it. Thanks for your help.

I've had the best success with "wickless" type humidifiers. They are a disposable item for me. Once a year I buy new ones, only because they stop working.

Hey doc Question about temps. My basement stays around a constant 70deg. I was told that might be a little low and might need to raise it some. What you think?
- Thread starter

The basement environment is excellent! Run the lights and get an idea what temps are like in the canopy/root environment areas. 70 is a great nightime temp, so if your lighting increases the temperatures enough you've got an ideal situation. You might like the Gavita 1000e's I'm running. Linked in the signature.

Thanks for the answer. I have my light. It's the perfect Sun 1000 but it doesnt put out enough heat to raise any temps. But my temps have been steady. 69deg. in the cool of night and 71 at the hottest part of the day so only a 3degree swing. Would love for you to drop bye and take a look.

71 is too cool. You might consider running a bare HPS or two for lights on.

Doc Bud - High Brix Q&A With Pictures
I have a cheese that started flowing early and stretched like crazy in just a couple of days. I think it was stress from leaving it outside to long and it stated getting shade before I got it back in one day shortly after I topped it.
The other hb plant I have doesn't show any signs though even though it was in the same conditions. I think it's just a lot heartier of strain (nirvana pure power plant). The cheese has been showing yellow leaves on the lower fans pretty much it's whole life. It's starting to get curled leaves on the flowers which I think is a sign of revegging.
For comparison the Ppp on the left in the next picture is only 16 days older. It has been fimmed, which didn't take, so I tried topping it which I think ended up being a fim. I just topped again, all of the Lst branches in the lower half. 12 colas should become 24, yes, I want a beast of a plant. Plus I want to take the top branches for clones. So it's had plenty done to it that should have slowed it down in relation to the cheese.
Btw I thought I'd include my brandywine and sunsweet tomatoes I'm growing hb as well. The sunsweet in regular soil last year tasted like candy already. I'm excited to taste them in hb.
