Please help with my white widow auto

I would probably not go higher that a full point, don't want to shock things! So maybe 6.7, 6.8. With issues, you can check before next water/feed and see if your getting closer.

There's no fixing what's already f'd, so the leaves won't look better, at this point your just trying to hold it together till the end.

The nute line I run suggests starting seedlings and vegetative girls in the low 6s, works for photos, cause you can start raising before you flip the lights... autos are just too fast. I start @6.4 and move to 6.5 fairly quickly. Once in flower I'll be 6.6 6.8 till chop. That would probably be a bit high for a salt based nute line, but not more than a .1, .2 or so.

I've been worried about how it will effect my house AC. I may just get a window unit. I do have a window in this room.

My RH isn’t so bad as yours but I am in Tx, GROWING IN MY BEDROOM WITH 2 TENTS, and a window ac works to keep it all going with small humidifier in each tent! U may wanna look at pulse grow vpd calculator cuz it’ll help tell u what RH to run based on stage and your current tents temps! U may not wanna run the intake at this point and just set the controller on the t6 to correspond to your temps and rh to stay in range that u can keep temps in! High 80s some people still have good success with as long as u can keep the rh correct!

The Ultimate Vapor Pressure Deficit (VPD) Guide

"Why devote an entire guide to VPD?" you might ask. The answer is that the vapor pressure deficit (VPD) is extremely important for growing plants. VPD helps you identify the correct range of temperature and humidity to aim for in your grow space. With VPD you can achieve the best results while...

@Proph here are all my plants for context. As you can see one is really bad. Spots everywhere. I had pretty much given up on it but the other 3 were extremely healthy until 3 days ago when this one started going downhill. The spotted one, I tried flush, calmag, recharge, just water, 1/4 dose base nutes, pretty much everything I could think of over the course of 3 weeks. Nothing seemed to help.

I believe it.. I've been trying to help a few others with their NLS issues, and in the process learned way more about it than I ever wanted to know, lol. The problem is that we have no clue of the amounts and ratios used to make this NLS stuff. It has no NPK values listed.. Once you pre mix it into your pots, you're married to it.. For better or for worse.. We've had people try every thing from flushing, to water only, to reduced feeds, to contacting NLS directly for help (which didn't help).. But without knowing what's in it and the ratios used, we're just guessing. Cannabis usually does pretty well in veg.. It's really hard to get issues in veg.. But once flower starts the plants nutrient needs completely changes.. And if those needs aren't met, issues show up pretty quickly. The run off ec is high.. But the issue is that NLS IS time released. So you can flush the ec down to say 1.1.. And a week later be right back up to 1.5. We don't know what nutrients are being released or in what amounts or when.. You took the car keys away from yourself when you pre mixed the NLS.. You're not in control of this ride.. You are a passenger, unfortunately. Adding more of anything is not the answer. There is already a major nutrient imbalance that has caused the issue..

that sound very similar to mine but i just use the vents for my fresh air from the room its in i don't know if any of that helps you but i use to vent it out of the room and with the longer ducting my RH was a lot better but when i put it in the loft my extraction became too powerful and was taking the air out to quick and my humidity was dropping to below 30 till i lowered my rvk extraction fan

Tom, I turned off my intake fan, dropped my extractor fan speed to 3, opened a bottom flap and I'm at 82 degrees and 55% humidity! Thanks for the advice

I'm so glad it helped you, bro and maybe open another flap i have 2 open as when i changed my ducting to really short just up and out it had me baffled till i figured out my fan was taking it out too fast and hopefully it may mean your not having to buy anything major to change your setup as i only need the humidifier when i only have babies in the tent and as long as I'm at 50rh most year-round i can get by

Ph of the water makes no difference in living soil.. You're not using a nutrient line ( or definitely shouldn't be) so ph is not an issue in this case.. The ph of your water, has nothing to do with the ph of the soil.. The ph of the water, does not effect the ph of the soil. The ph of the soil is buffered to stay at about 7. It's incredibly hard to break that buffer. And to know if you did, a soil ph probe would be needed. If the bottom 3rd of the pot is strictly NLS, then flushing won't do much. Again, don't feel bad and don't over think it... This is more the fault of the NLS product than something you did or are doing. You're not the first, or the only one going through the exact same thing right now.. I think there are three other active threads in the infirmary, plus all the ones from months ago.. We haven't seen it used successfully yet. Everyone followed the exact given instructions to set up their pots. So don't feel too bad about what your doing. I hate to say it like this but the plant was doomed as soon as NLS was placed on the bottom 1/3 of the pot. Every plant is different. Some can't handle heavy feeds, some can tolerate it for longer periods. But all of your plants will more than likely experience the same thing, unfortunately. I always offer to help from start to finish on the next grow when something like this happens.. So tag me as soon as you start planning your next seed. We can walk through it together and clear up any questions before they become issues. Again, don't be hard on yourself, this is a product issue, not grower issue.
