Possible magnesium issue

[chris harris]

Hey man, you're not alone. Had the exact problem with Sunshine mix as well. Was using Promix HP, ran out, ran to Home Depot, picked up Sunshine Mix #4, thought it was all the same shit, boy was I wrong. All plants put in there turned pale green, purple stems. Spent 2 weeks foliar spraying Epsom salt, cal mag, etc, etc. Nothing changed them. Decided to flush, run off came out 4000 ppm( .5 scale). Numerous flushes, and re potted into Promix HP, all fine now. No more Sunshine Mix for me.
If it was me, I would flush them hard, till run off is down into an acceptable range, then go from there, or repot. Good luck.

salt lock up. Due to high PPM levels. I say nuked because salt kills the micro-beasts. I rely on the biological web of life in soil. Your soil is dead, based on my experience and what i see. I understand and have been in your situation bro. Its a tough spot to be in. I don't blame you for switching companies. Different styles lend to different companies. I apologize for my offensive behavior. I could do a better job leaving my ego out of it and just relay the information. Try top dressing some worm casting in on the next watering, it tends to help in this situation as well. Fox farm Sledge hammer is a good one shot wonder at times too when i mess something up. Helps restore damaged soil, its just yucca extract. again sorry for being a jerk.

i could be wrong, i haven't used the stuff in over a year now. But I always added stuff to it, I never used it as a stand alone, because Its not soil, its a soil-less medium. Sorry I guess this is why i'm glad i'm mixing my own soil these days and not praying what is coming out of the bag is what it says its suppose to be. I suggest mixing your soil and letting it sit in totes for a month or two before you use it. I really suggest getting into TLO or bio organics, what ever name you wanna call it. Water only or no till soil is great way to go, hard at first, but once you get use to it and establish a good soil, things seemingly take care of themselves and require minimal inputs overtime, compared of buying new every-time.

Pretty much same story, they ran out of promix or something like that. All the plants with them have purple stems. The medium was purchased like 6+ months ago and dried out too.
I did take the 1000w down to 750 then switched to 4x8 t5 and they are soaking up water faster or drying faster. I'm spraying calmag , N ,and some b-vit. I notice a difference with turning more green but stems still red

Truck no problem man, big ups on coming forward with that. I'll definitely add worm castings to the top. From what it sounds like your saying all the micro teas I'm feeding them have been going to waste Because the micro herd is getting burned

brutally overfed and also overwatered. youve burnt the roots so bad that the plant cant take up any nutrients and thats why your seeing all the deficiencies. especially the mag because mangesium is the central molecule in the chlorophyll ion and is an essential component in the photosynthesis process. nothing to do with your soil mix. my suggestion would be to never feed until they ask for it. they need a hell of alot less than everybody thinks and feeding everytime you water is bad advice and watering everyday is even worse. feed when they water when they ask.

woops cant edit my posts yet. feed when they need water when they ask. i like the water water water feed wwwf wwwf....schedule myself and i end up only feeding 3-4 times in a 3 month cycle. pro mix hp in 2g pots

Hey, you seem to be knowledgeable about this. I can definitely see what you mean . I got a few questions that I could probably answer myself but why assume when I may get the answer from you. Are the roots really burned like damaged to the point of not being effective in the future or is it more clogged like locked out? Guess I'm just nervous the damage is not reversible. I do see improvement but I don't want to lose yield and quality. There definitely overwatered from the flush. biggest question I could ask is should I let them dry out again and flush just water until ppm are down to say 800ish, then let them dry again and then feed nutrients. My worry is that they are so deficient that they will starve without any nutrients and be damaged even more. I am foliar feeding which is great but I understand the importance of a healthy medium(which may sound funny saying this after my medium is a mess)

yes damaged to the point of no return. and yes the plant Can grow new ones but its gonna take at least another 2 or more weeks to start to recover. better off starting over and dont take clones from her, sick plant = shitty clones. cloning is easy and every method works. why people have trouble is they take cuts from unhealthy plants. if you do decide to save them no more food straight water and microbes via compost teas and soluables(great white,mykos,sub cuture b/m, pirahana, tarantula) for example. dont bother flower them lookin like that they might finish but most likely will die in week 3 flower flower. yield will suck and quality thereafter cant have one without the other. if you get a good yield you grew healthy plants and big healthy plants will ALWAYS give you quality bud! whats your room dimensions and light set up?

There definitely overwatered from the flush.

overwatering is watering to frequently. ie watering everyday. flushing is not overwatering.

 

[deadhead77]

Like 10x10 with 3k and an 500w led . I'd be surprised if I watered them too frequently. I water the more but less often. I've been spraying foliar and seem to be coming back around. I like the idea of just flushing bene teas. Good thinking I was just going to do like 300ppm ph RO water flush but tea better idea thanks man.

Sounds like you got the right amount of light for the space.
From the pic you posted signs point to overwaterd(clawing leaves, speed bumps on the leaves) over watering and over feeding are super common i was guilty myself for years...the benies are to feed the mirobes to rebuild your root system and for.a healthy rhizosphere. I wouldnt bother flushing with tea, just do what you had planned, ro flush to get your ppms down then add your bennies at the end. Then low ppms for the rest of the grow! And bennies every 2 weeks as thats how long they live for before the population declines. Overwatering has the same effect as overfeeding, rot the roots hairs then they cant take up nutes leading to deficiencies. I average 1.5p a 1000w light doesnt matter strain or nutes i use one part nowadays with some cal-mag and microbes. KISS. Ppms never exceed light wattage ie 1000w 1000ppm. that being said i have an OG that doesnt like anything over 600 and since my tap is 200 i might feed once in a 30 day veg! Hope that helps!

Very cool man and very thought out. Before I had a 1yr old kid I could think things out like that. This is why icmag is so awesome. Thanks again .

ya if there was too much lime to start, the micro heard would have a hard time gaining a foothold. Lime burns roots too, which makes it hard for the plant to uptake nutes, which is why i recommend yucca extract or even aloe, it helps repair the roots and soil that got hit with the high concentrations of super high PH. This is why i eventually went to a good soil mix weather a combination of bagged mixes and eventually composting my own soil so i knew what was in it each time and that i was in control of the inputs, instead of dealing with the random and seasonal changes in mixes, which is why i would pic 3 or four different bagged soil mixes plus a little plain well rinsed Co-Co, perlite, and some quality worm castings. Sorry i don't have too much to help you get out of the mess you are currently in, but if you can get a good soil mix going for your next grow you won't regret it.

 

[deadhead77]

Thanks truck, I have thought about aloe but I figured I'd keep it simple. I have grown my own aloe to feed to my plants with and saw a good improvement so that may be a good idea to do again. The plants have definitely come back around and have shown about a half inch of new growth all around with green coming back fully. Thank you for all your help with the plants when life gets to be too hectic to figure out myself

Hey guys I got an update and I'm hoping for some more help as I've gotten some good help before. I flushed my soil again as it just dried out and I checked the parts per million it was 1300 and the pH was 4.5 even with the dolomite lime in there and I pH the water at 6.2 before I used it to flush. There about 2 months into veg right now. Do you guys think I should keep flushing? And what should I do about a low ph in the run off. Thanks guys
