Leaf diagnosis request - burn or deficiency?

[Tangerine_]

Are Annie and curious2garden the same person? What's interesting is that you won't give an answer. I don't need to start my own thread as I don't have any issues to address.

So you expect me to what? Take the time to run the OPs numbers for you? He already found help so why on earth would take the time to do it for a user that has done nothing but troll his thread. (rhetorical, don't bother answering)
Run the provided elements yourself if you think my advice/opinion/experience/info is wrong. Simple really.

I presented my opinion based on the info he provided. Sandman can take it or leave it. Its not my garden.

OP, I know you're currently working through this but I gave my advice base on what I observed as Cal lockout.
(small round necrotic spots starting to form) and that the plants were struggling to uptake micros...particularly calcium, followed by K, Mag, and Fe. There are a few things that cause this. Could be the sulfur or the phosphate. It could be polymerization from SI but I'd double check with @cannabineer. Adding additional inputs on top of base nutes will cause reactions, throwing off calcium ions (cation exchange.) You know all of this now and you could expand your reading on it as you go along.

Beer and CtC know their stuff. Glad you're getting squared away.

Sorry bout the thread hijack. Just trying to lend a hand.

I never said I don't buy ferts anymore. sandman is right about the amended super soil thing. Building grow space can be expensive, true enough. DaFreak takes segments of what I write and uses them out of context to support his own argument. Stupid.

No, what's stupid is telling somebody in a pure hydro setup to use water. Dude, you have shown yourself to be full of shit and little on knowledge. Get over it.

Thanks for the detailed explanation! I will make a note in my log for the future at least so i can be aware of what to watch out for.

sending you a couple of links. I wrote my response kinda fast because I had to run out.

How hard is it to throw some plants in dirt and water them? With some occasional maxsea of course

No shit, right?

Tangerine, you must be a scientist or something. If you're better informed, why didn't you just say so earlier? You say you're not going to answer me, but then you answer me. I'm still not convinced that you're right, but then maybe you are. I'm into the amended soil style because I discovered that it's better if a grow mimics nature, even if it is slower. Hydro is fast, but so easy to screw up.

DaFreak, you did it again, using just a fragment of what I wrote out of context to support your argument. Not smart.

Great advice, use soil.

I mean, I am... just for a different room. Seems like no one here wants to actually run things and try for themselves just repeat bro-science. And it's not like they recommend using "plain soil" you need to buy a ton of stuff amend it and let it cook to work properly. I've got 15 gallon fabric pots.... I will give the no-till organic thing a try in a year or so. Right now I enjoy hydro.


I don't really care to go along the tribal lines of "organic vs hydro" etc. To each their own.

 

[DaFreak]

I was being sarcastic. People should not tell others growing hydro to do soil and vice versa unless they are killing their plants, which you are not. Yours are showing slight detox is all as you already know.

In the interest of full transparency here is the crispy bud from the first post and one of the other buds from the same plant. Colors are starting to show underneath the LED.

If nothing else perhaps someone else can learn from my mistake. I understand there is no fixing the damaged/burned leaves so I just left them alone and when they fall I pick them up.

PH is now stable between 5.8-5.9, I adjust it down as needed instead of letting range up. PPM has been reduced.

 

[polishpollack]

I've seen worse. You've cooked them with something but not sure exactly what. I don't think it's a calcium problem as you're giving calcium, if memory serves. I stand by my earlier statement of just use water, clean them out of nutrients, let them die, and be happy as they actually look pretty good, considering. Looks like they're nearly finished now. It seems you understand super soil, let it cook, etc., so I'd consider doing that next time. It's slower than hydro but will be much easier and more consistent, and I would recommend to everyone that they at least try it to see if it works for them. You mix it, you get it a little wet to activate the bacteria, let it sit for 6-8 weeks to break the ferts down, then plant it in. It's almost perfectly foolproof. Just water when dry. Subcool is selling charge packs where all the stuff is sent to you, I think you just need to add worm castings right now until he includes it in the pack, which he's working on. If you scroll down there's a 2lb cheaper charge pack. I don't know how much soil each charge pack is good for, so you'd have to ask him via contact us. https://subcoolssoil.com/shop/ Let us know what you decide to do. There's another company out there that make some good products people should know about called Buildasoil. You would mix that in the soil with the charge pack, unless Sub has done that already.

Great advice, use soil.

Actually, it is good advice. It much easier to grow well in soil. Hydro takes a lot of TLC to get your THC.

No worries, i'm a tinkerer and will give both methods a try. I have some compost cooking in the yard but it will be at least another season before I have time to give it a try. Thanks for stopping back with a more in depth response. You are correct, the ppm is down to 800 now, will flush and drain the tank again this weekend and refill to 700 level. I don't want to completely starve them but will be reducing the feed significantly.

JFC, No one said he wasn't fertigating with enough calcium.
Just stop. The OP has thanked you. Move on.

That still isn't an answer.

Come back later and mention what happens with the grow. I'm not sure compost is a good idea, but you can do what you want. Super soil isn't compost.
I've gone through this kind of thing before, where I come to a thread with a really different understanding and the flame war starts. When you're using that much stuff that is easily absorbed like hydro ferts are, the chances of over ferting are very high. I've seen it so many times. What gets me is those whose say something like it's a calcium ion problem but there is no evidence to suggest that. When a grower gives calmag, it could be too much but at least it's in the mix. Years ago, people always blamed pH. That has been swapped for more complex explanations, but that complexity doesn't make it correct. If a poster doesn't really know what is going on, it's better if they just stay off the board. But that wouldn't be much fun, would it?

Well, I didn't understand it 100% that is fair, and yeah I came here to try and understand it. I know the supersoil recipe =/= backyard compost, just letting all the used FFOF etc break down with fresh compost etc while I wait. Might as well let the worms etc colonize and break it all down for me.

This really highlighted the importance of running a single pheno through hydro system to me, here's a shot of another girl in the same system on day 40. Let me know if you spot on leaves/issues but she doesn't have any of the crispiness or spotting other than just slight over ferted tips.

 

[polishpollack]

I don't see anything wrong except the leaves appear pretty dark green. The problem with making photos like this is the image can be a little deceiving. That really looks good. A little too much fert perhaps. I think I would just taper down in the days to come your ppm as you're doing, then nothing but water for a while. Almost there. I still don't understand why calcium ion was stated to be a problem, but maybe that was a different plant. Those new pics look perfect to me.

 

[Tangerine_]

That still isn't an answer.

Why, because YOU don't understand it?

When you're using that much stuff that is easily absorbed like hydro ferts are, the chances of over ferting are very high.

You're on the right track but still not comprehending CEC

If a poster doesn't really know what is going on, it's better if they just stay off the board.

Says the poster telling a hydro grower to use straight water.
