mag def?

2x 400w HPS
promix bx
general organics nutes, with N.o.t.G. bloom khaos
ph 6.0-6.2 R/O
replaced Cal/Mag with demeter's destiny

problem started on last week of so, ran 1 tsp of epsom salt with 1 tsp of demeter's destiny today. should i be looking at something other then mag, wanted to keep demeter's destiny so i can continue use of Bloom Khaos.

Almost looked like heat stress.
Do you have any calmag to feed?

know it is not heat stress, room never gets over 75, and is effecting them all, this one is farthest from light. have cal/mag but prefer not use it as it is calcium nitrate.

How far away are your lights from your canopy?

more details please. how often are you feeding? whats the soil? how much run off? is that branch in front of a fan getting wind burn? side shot? how many times have you added the calmag?

around 12" from plants

decided to pull them back some more, and see if it helps at all.

Ok grab a pen and paper. #1 I congratulate you on using Promix. IMO it is the best for soil less grows and has always come perfect out of the bale(unlike fuck farms). #2 Do not believe in the hype of Organic nutrients (organic foods you eat yes, but not organic nutrients). Myco is the only thing organic you should use and its already included in the promix. #3 for promix you need full blown hydroponic nutrients that supply their own micros. NO SOIL, TERRA, whatever else they want to call them nutrients. They usually lack a lot of the micros because they expect "SOIL" (which you do not have) to carry it. Pro mix is fully inert and has no calcium and needs to be treated as passive hydro. Now to your problem. Temp/humidity is the logical first guess by the taco effect, however you claim temps are OK. No mention that I can see on your humidity so if its also ok (between 30-60%) you have simply nuked your plants. You will need to flush or dilute or a combo of both. DO NOT FLUSH AT 3:1 right now or your plants may not make it. Before flushing if you do not know PH runoff, I suggest digging at least 3-4 inches down into you soil (or as far down as you can go) and scoop out 2 samples of soil you can place in a shot glass (prefer a double shot glass for this and fill them up). Now take each of these samples and place it in different dixie cups. now take one sample and place the same amount of water (7.0PH) using the same shot glass in one of the cups. The other cup place 5 times the amount of water. So one cup has 1:1 water to soil and the other has 5:1 water to soil. let it sit for at least 5-10 minutes and get a ph reading from this slurry. this will be needed first before you do the half ass flush I mentioned at the beginning. post your PH results and I will then instruct you with more details on how you are going to do a half ass flush in an attempt to save those plants. whatever you do DO NOT ADD ANY TYPE OF NUTRIENT ANYMORE. NO CAL MAG NO EPSOM NO NOTHING. You will simply create more problems

humidity is around 24% jus got my meter in there. jus watered them last night so nothing can do about checking runn-off right now, need to pick up my soil ph tester back from friend today will check mix PH.

humidity is borderline low IMO. I gave you detailed instructions already on how to measure ph runoff because I already anticipated you listening to everyone else. (I knew your soil was wet already) This is called a slurry test. Almost same as runoff if not maybe even better depending on situation. Also if you can not get humidity higher, you MUST use lower ppms when feeding at all times. If your base nutes have calmag in it, no additional calmag is needed most of the time. DO NOT USE ANY SOIL TESTING METERS AS MOST DO NOT WORK

Rh is a lil low...i think u just burned it. Those hydro store nutes are a mofo.

Could be potassium as well, unless its just severely burned somehow

P or K deficiencies only happen to master growers that know what they are doing (and still very rare), people using solely organics (those organic growers that like to complicate things and use 20+ different organic amendments all competing against each other), or people who constantly underfeed. (by the pictures and his posts it is evident neither apply here). They are simply nuked... forgot to add you can get a p or k def by using nutrients with bad ratios (not designed for what you are growing)

thanks for letting me know the small box ur view lives in. have grown multiple times from seed/clone to harvest with general organics. (So have many others)

well i did some more research as i didn't wanna dig up my root zone to ph test it when a flush with ph'd water would correct. so i did more research and found an answer that better fits the situation i am experiencing in my room.

Boron Deficiency

http://www.growweedeasy.com/boron-deficiency-cannabis

makes sense to me, looks like potassium deficiency except it is on new growth made me think why would a deficiency be on new growth, since the only thing change was location, always feed lite and get plenty of run-off.

Thats right your newbie ass that dont know what you are doing nuked them. It dont matter how many people successfully use something, you just proved you werent one of them. Add all the moron... I meant boron you want. Let us know how that goes. BTW Boron is one of the least used micros by a plant. None of my nutes even show Boron, not to say it isnt there, but you will quickly realize this is a mistake adding more Boron will not fix. Humble yourself if you ever want to learn anything, or you can keep being our entertainment. You fucking up your grow, to then ask advice, to then wanting to be the expert is the type of shit that makes our days. Once aging good luck

where did you see one post that said I was adding boron you dumb ass and since you think you add boron to fix the problem I'm glad I didn't listen to your advice.

look at your prior post talking about Boron. Also 540+ posts with as many likes as me who has only around 90 posts. Some people give good advice, others needlessly ask for it, then ignore it, to then start arguments. Which are you? Im done with your ignorance

Yea looked at them again and yes still never said add boron, guess u never bothered to look of read the link.
so here it is.

"Boron is not absorbed well by cannabis without enough potassium and nitrogen, or if there isn't enough moisture (for example if plant is underwatered or humidity is too low). That's why it is recommended you water your plant with a regular dose of nutrients below.

A plant is more likely to show signs of boron deficiency when the humidity is very low (below 25% relative humidity in the air), so you may help humidifier may be needed if your grow room is very dry.

Please note: Boron deficiencies are more likely to happen when a grower is using heavily filtered or reverse osmisis (RO) water to feed plants, since boron is found in most tap water.

If you suspect your growing cannabis plant has a boron deficiency, flush your system with clean, pH'd water that contains a regular dose of cannabis-friendly nutrients. Old damaged growth will likely not recover. Watch plant over next few days to make sure that the problem stops spreading to new growth."

nothing says add boron....... only that a flush and lite nutes, the RH% is my real problem.

wow u got as many likes as ME, oh well guess that happens when u wanna jump on other post all the time, very few of my post are looking for help...

Say it with me, You're Good Enough, You're Smart Enough, and Doggone It, People Like You... lol
