Niiice good response... Did the bottom leaves start yellowing after you stopped the Nitrogen boost? I would not be overly concerned at this point. If your PH is in that range you're fine. Once you drop under 6.0 you will start noticing problems and pretty fast. The main thing is to do everything you can ASAP because plants can go downhill fast. One thing you could consider is adding a bit of dolomite lime to start stabilizing your PH. They have fast acting lime at TSC if you have access to one of those, otherwise Home Depot has dolomite lime for a few bucks. This will provide some micros and pull the PH up towards 7. Most people recommend about 1 TBSPN per gallon of grow medium. If the feeding schedule has eliminated the N and you think you might need some maybe you could just add some more castings as a top feed too. I saw that you use them for your medium and maybe you have some on hand. When I used Fox Farm nutes they cut off Nitrogen a bit earlier than they should have IMO and my plants showed N def when I followed the feeding schedule. Eventually I tossed the schedule and the nute regimen altogether lol.With my pH up and down I got a liquid ph tester (came with it). You put your solution in a vial and add 3-5 drops of the ph tester solution. It changes colors and that color is measured on ph scale. Before I fed the ladies I tested the nute solution. To me* it looks like it was yellowish green which indicates a ph of 6.5. When I tested the run off it was more yellow (under 6.5) so it seems my soil ph is low. That makes sense since I'm showing signs of a cal/mag def... I'll find out for sure when my digital tester gets here. It looked like it would be today but now it's looking like tomorrow or Wednesday... fucking USPS snail mail.
Are you following the Humboldt feeding schedule? I sure am. How long have these been in the containers since transplant? They've been in the 5 gal warrior pots since their original transplant, about 6-7 weeks ago. Is Humboldt using a cal-mag equivalent? Yes. I have HB Equilibrium (cal/mag suppliment) and I use it with just about every water/feeding at 2.5-5mL per gal. How are your temps running now? Up until this week the temps were a steady 83F (lights on) and 76-81F (lights off). With the a/c unit I can dial in any temp during lights off. Lights on this week (with the heatwave) the highest temp reached was 93F (lights on). Currently the lights are on and the temp is 88F so it's cooling off a little. Are you using city water, well or R/O? I have been using my city water which has been dubbed "OK" to use by many growers in my area. The ph tests around 7.0-7.2. The last few days I have been using r/o water (culligan) which ph tests around 6.7-6.9. I haven't seen much change since using the r/o water.
You mentioned the possibility of a nitrogen deficiency but if there is one it's from being locked out. I used HB Verde (16-2-1) as a nitrogen booster up until a few days ago. I have no problems continuing the use but the HB feed chart has it being stopped at the first week of flower so I stopped adding it.
I think the main thing is my ph. Once I get that down I shouldn't have many issues. Before I started this grow I wasn't aware that ph was so important. Now I do!!well as many issues as your having the buds seem to be coming in ok
Yep PH is pretty much the most important lol. I learned the hard way, you're right on top of it so don't worry. Given you're running Co2 your temps should be fine. Not positive but I've always been told they can sustain higher temps with higher ppm Co2. You're right on, the fewer adjustments the better. You can use the PH up and down but the important thing is not to chase your PH. Put in exactly what you desire to come out in the form of runoff. I will give you an example.The yellowing started about 2 weeks ago, and since I thought it was a N def. I started using the Verde again. After seeing it wasn't on the feed schedule I completely cut it out. Being that it's now week 4 of flower, I'm trying to be cautious not to 'over treat' any problems that come up. The last thing I want to do is over feed. Once this ph tester gets here I should have a better idea of what I need to tweak and just how to do it. Instead of the lime I can use GH ph up and down can't I? That was the whole reason I got it yesterday lol I can't spend anymore $ on ph adjusters during this grow...
I do have some left over worm castings to add to the top of the soil. I will do that tonight. Another thought was getting some guano and throwing that on the top of my soil.
Dude it's like 88 today and I have no complaints lol That's what a few days in the 100's will do for ya. The temp being that high for a few days shouldn't be too bad for our girls. My girls have plenty of c02 to keep them busy when it's this hot so the temp, although it sucks, doesn't bother me much.

Same thing here except it's only on two flower tops on one of my kush plants. All the others seem fine. I read somewhere that orange hairs this early in flower is a sign of a hermie, but I don't see any ball sacks. Once my ph gets fixed I'm thinking the nitrogen problem will go away. If not I'll go back to feeding them the HB Verde.Im getting those weird fucking orange hairs too, not sure what it is.
It's only on my desert dream on one of the tops of a lower branch, i'm starting to think it was from my fan hitting it when it turns but im not sure.
It's pretty much like all the tips of the white hairs are turning orange/red like they are heat burnt or light burnt right?
only reason why I dont think its that, is cause the part that has it is like at the bottom of my plant way away from the light probably like 2 feet.
and I agree, GH does cut off the nitrogen way early I now have to wait like a week to give my desert dream any nitrogen cause I have to flush tomorrow hopefully she wont bite it.
Adjusting the solution ph is gonna have to do for now. Adding lime to the soil at this point isn't an option for me. Before I start another grow I'll most likely do a few things differently. If you're suggesting that adding lime to the soil will help in the long run then it's something I'll definitely research. I have to move out of my house by Aug 15th so I'm trying to take the easiest road to harvest this time around.Yep PH is pretty much the most important lol.

If you want a medium PH of 6.5, put in 6.5 solution. Lets say your PH trickles down to 6.0 and you want to bring it back up. Lets also say it doesn't seem to come back up when you feed with 6.5 solution. Don't give it 7.0-7.5 solution attempting to equalize it it for a result of 6.5 runoff. You might think its working but you could be doing more harm than good. Lots of people do this thinking that it will work out, I've done it when I first encountered PH issues and learned from experienced growers that its not a good idea.
PH up and down work great for adjusting your solution, but sometimes your medium needs to be adjusted. The more food the plants get and eat, the more acidic the medium tends to get. Hence, later in flower when the plants are able to take a higher ppm of feeding the PH tends to dip. This is where lime is beneficial because it can help to keep your PH close to neutral in the medium. Lime has a PH of 7.0 and when you use it in appropriate amounts it helps to stabilize PH in the medium. I usually administer lime into the soil at every transplant as well as after the second week of flowering or so. This provides beneficial nutes and maintains a neutral-ish PH.
wow that game was awesome .. I remember that being the first multiplayer game where buddies and I could spend the WHOLE weekend non stop playing,,,Woot. Getting your first pH meter feels like you just upgraded real hard. Like Goldeneye 007 for the Nintendo 64 when you get the Golden Gun, you are unstoppable now!
When I'm talking about adding the lime to the soil I'm talking about amending the top of the soil just like you would with your castings or guano. It is water soluble so when you water the plant from the top it gradually breaks down every watering and works its way into the soil. It takes a while for the plant to absorb it since it has to start breaking down first. As long as your runoffs are in check you should be fine. I still add to mine for a PH buffer and for the added comfort of cal and mag. I've only ran into PH problems once before. Now I don't worry much as long as I amend my soil properly with lime. I've recently switched from finely crushed lime to powdered lime which I feel is faster acting but not necessarily longer lasting.Same thing here except it's only on two flower tops on one of my kush plants. All the others seem fine. I read somewhere that orange hairs this early in flower is a sign of a hermie, but I don't see any ball sacks.

Side note: I got my ph tester in the mail today. I also got a PUR water filter for my faucet Lights won't be on for another 9 1/2 hours but I have some experimenting to do so it should be a fun night.
Laptop gun raped the golden gun.Woot. Getting your first pH meter feels like you just upgraded real hard. Like Goldeneye 007 for the Nintendo 64 when you get the Golden Gun, you are unstoppable now!
Not Real.Laptop gun raped the golden gun.
nuff said.
There is a special 7.0 calibration solution that should be used to calibrate. I'm not sure what came with the pH meter. You can find the solution @ hydro shops and pool supply places. Also, most hydro shops do it for free. Also, make sure you are storing it properly and rinsing with distilled water.Ok so my digital ph tester is here and the lights are on.
First I calibrated this ph tester in the two solutions that came with it. Next I tested the ph of the r/o water I was getting from the store. The ph is 6.2!! The water straight from the tap has a ph of 7.2. I still need to hook up my water filter and test the ph of the filtered water.
Getting the r/o water was supposed to help but it's looking like it did more bad than good.
EDIT: Surprise, I'm confused. The water coming from my tap after being filtered is at 9.4?? wtf?? Something does not seem right with that reading. How does water straight from the tap read 7.2 but that same water being ran through a filter come out with a reading of 9.4? Any ideas?
