I would test your water but until then use distilled water. Keep going with the epsom foliar.
Alright. I apologize for lack of update. Have had some personal things come up in the last few days. But I did possibly find my culprit... We all know humidity is necessary for the plant to grow proper obviously. I recently found my old caliber iii hygrometer, I figured it was broken when the humidity read.... "--" which means it's literally a desert with zero humidity.... I went and bought another hygrometer, grabbed a caliber 4, and same reading, except this says "LL" obviously it's too low. But my whole house is this way? Normally we have just really low humidity like maybe 20% in the whole house. But lately I've noticed the air just in the house is super drying to the throat. An that's what had me think to check humidity not just in the grow, but all through the house. Sure an shit, 75-80% of the house air is so dry it doesn't come up with a reading at all?... Somehow I managed to suck all the humidity out of the air and in doing so the plant seems to be eating itself to death as one person suggested I over fed with nutrients which would make total sense in this case as the plant can't hold it's water literally and is burning up through nutrients moving too fast in it's system? At least that's how it seems when I read up about the relation of humidity and plants. Could 0% humidity cause this or weird nute deficiencies/toxicity? I'll post up progress pictures here in a bit as soon as I find the camera. But it's only gotten worse and this is the only thing environmentally I can think is wrong? 72F Degrees and zero humidity? Otherwise the plants shouldn't be doing this as some were just transplanted weeks before this showed up when I made the thread. Same soil outside didn't have this big of a problem, the problem outside was because in an unheated garage the temps never went above 65F and dropped to freezing during lights off. So that didn't help much, but they didn't start burning up like this, they just stalled flowering for a month and went dormant until shortly after putting the flower tent in the room then they spring back to life but then this happens? So logic would say it's the fan sucking all the moisture up?
After a few days of spraying at least twice a day with plain tap water, and they perked right up. Here's they are as of now. Should I get a humidifier to up the humidity at least a bit especially since my flower tent is taking a hit as well it seems from the humidity?
Humidity is very important and if temps/humidity are outta wack can cause deficiencies.

Flower tent as of now is 74-78F lioghts on and 65F Lights off
An in the room for the plants in veg it's about 75F but for both room and the tent the humidity is none existent, zero percent.
I'm going to get my water and soil tested here real soon in a day or so to make sure everything checks out. I just got a humidifier as the household itself needed it anyways. The humidity is now hovering around 35% - 45% inside and outside the tent. Should I give a few days at least to see a difference? The misting now and again helped to a point but didn't stop the progression of what's going on. Could this be a manganese def/lockout given the brown mottled spots in the one picture and they are all in the same soil?
Hello. This is literally my first post and was also using BAS nutrient kit, ewc, and 99% shy of using Calmag for nutrients, I have to say I am currently into my third grow period and I have used these nutes with a combo of coconut water powder and I noticed the nutrient kit works better if its ground down into a powder and halved per gallon of water. I grew in happy frog and sunshine mix that I mixed together. My first go around was with hso bubbas gift and I learned the hard way to lean out the nutes cause I burnt them pretty good. Second grow was hso lost coast Hashplant and I did better with the less nutes. My grow now is ridiculously lovely and no problems.
Sorry saw I forgot to put 99% organic.
Checking the local water department website it states our hardness or whatever at 70-80 average, I know this doesn't correlate to exact amounts coming from my tap but figured it would give a rough idea.
The other thing I'm thinking besides two of the vegging plants being slightly rootbound, I topdress a literal pinch of fish meal and the dead leaves started to green for a day then got worse over night.... I'm now certain it has to be soil compaction? All the pots are taking a lot longer to soak up the soil. It just pools there for a bit then slowly sinks through. I know compacted soil can inhibit phosphorous uptake but can it also mess with other nutrients also or is phosphorus the most affected? If soil compaction with my zero humidity was causing this, and I have added a humidifier now to get humidity to about 40% now. How would I go about fixing the flowering plants? Being as far in as they are now and the veg plants I know I could just transplant with more pumice mixed in as I probably didn't have enough and used rice hulls mainly for my aeration amendment at the time of reusing the soil, and didn't add enough hulls to make up for the last runs that broke down enough. I'll get some update pictures up again as I honestly am a bit lost at what it could be. The lights make it hard to tell whats wrong even with the glasses provided. In natural light the leaves are dark green, almost like nitrogen toxicity dark, but doesn't phosphorous also cause this and the fact of the leaf tips/edges turning brownish/gray almost like a fungus or something growing on it? I know it's not, but it looks that way. I'll try and get a macro shot of some of the leaves up close to see the damage.
I'm not sure if this was asked but what is you feed and water schedule( f for feed, w for water only. I do fwwwf. Only reason I ask is i am doing a similar type of grow with BAS products for nutes but I was growing in 50/50 happy frog and sunshine mix. My first grow I was on more of a fwfwfw. I had the same type of thing happen to me. I'm very new to this whole thing but I'm pretty sure I over fed the crap out of them. My second grow was way better when I leaned everything back. I also brewed tea but now I just grind my BAS nutrient craft blend into a fine dust and add roughly 3 to 4 teaspoons per 4 gallons. No bubbling or brewing just stir then water.
Oh and I kept my ph between 6.6 and 7.
Okay, here is the three in veg now as they sit. I want to say the two are making a slow recovery but the other isn't yet. It's getting worse and it's the one with the most pronounced greyish patches/leaves. As I said I got a close up of the leaves on all three.
First plant - we'll call it square, she was topdressed with just shy of a teaspoon of fish bone meal a few days ago like stated along with a coconut water foliar and also a kelp meal tea then next day to cover any other slight problems that may have been. Rest of kelp meal tea was drenched into soil
Second Plant - She'll be known as Tidy for now. I also topdressed a slight teaspoon into the soil and coconut foliar with a kelp meal tea followed the next day.
Third Plant - Happens to be a he, was more or less a "test plant" to see how things are affected given certain circumstances or deficiencies. He didn't have anything topdressed yet, other then foliar feed coconut water and kelp meal tea with drench. And epsom salt foliar a few times as advised. Why not, other then maybe a seed project way later down the road for shits and giggles but for now, he stands as is and want to play around with him in veg for awhile as I said, perfect candidate for these purposes, no loss. Unless your a breeder of course. An yes I understand it's bigger then it should be for the size of pot just like the first plant. Obviously rootbound. But for the moment until I can get to the store for some compost/ewc I can't transplant up at the moment. So my main question(s) are this.
1. In anyone's opinion have these bounced back much? I want to say they have some, but other days look worse, so not sure what to say, as why I took in more natural light instead of the grow lights.
2. Regardless whether the deficiency(s) are solved for now, what would the pics likely say to those in the know?
3. What else can I supplement or top dress until it's truly too late to keep them in these 1gal pots truly? Like is it possible to supplement amendments and foliar even if it had to be everyday or every other day to keep em happy for awhile until I can transplant?
Kind of just give every other week until lately when they started showing deficiencies, now I'm trying to figure it out.
Thank you much for the help as always. Much appreciated.
