Here is a chart showing nute uptake at different pH levels. It looks as if in a soil grow that most nutes begin to be locked out above 7.0.

Sounds like this "book" wld make good kindling in the fire place because he is talking dog farts. I grow in soil and I don't " abandon" my grows and hve seen ph problems and ph lockout first hand. But JAAM is right...maybe he is right and all of us stoner/growers are wrong.

Don't take offence Hammy -- just his opinion. I'm sure he has grown his share of weed, and he does own a hydro store. He just doesn't think PH is always the problem -- and I am inclined to believe him in this case -- I over nuked them and it was dramatic -- PH problems would have been more gradual -- I'm thinking. Anyway, no offence intended.

Sol, those plants have been in that soil for weeks, and yesterday they looked fine -- better than fine -- OVER NIGHT that plant went south. The rest of them are just fine. That plant is the only one I fed yesterday -- it has to be related to the feeding, not the soil, not the PH. I am not a retard or anything, but I may have picked up the same bottle twice or something. I'll deal with it.

And thanl you Puffin, I think you have a handle on this thing. I will just water for the time being. Should I snip off the bad leaves?

 

[HemperFi]

Just wondering if it would be a good idea to trim off the bad leaves?

 

[Roddy]

Only if dead, if they can survive, I'd leave them.

 

[HemperFi]

You said in a prior post that the pH was 7.5. If it was that high, it could be pH problems. Can you remember how much of each nutrient you put in? It would be nice to know if this was nute overload.

I just cannot believe that this is heat as it happened overnight when the lights were out.

Had nothing to do with heat -- I doubt seriously it had much to do with PH as well -- I screwed up when I fed her -- Only one plant is affected -- the one I fed. The rest of the plants are just fine.

Thanks Goddess

should I trim off affected leaves?

 

[HemperFi]

thanks Roddy

Okay, live and learn. The PH in the soil in that pot tested at 7.5 after I had flushed it the first time. It tests at 7.0 after the second flush. The rest of my plants test at 7.0 soil. The soil is neutral PH, and I believe that is okay. It is the neutrient solution where it is important to have the PH in the 5.5 to 6.5 range. There is only one plant which is affected. If I had PH issues it would most likely have been showing up in a gradual way -- yellowing of leaves, leaf burn, droop, something would have looked wrong already. All of my plants were beautiful until I opened the tent this morning, and the one plant I watered yesterday was in terrible distress. The rest of the plants are fine. I screwed up the watering/feeding. I will be more careful in the future. Sorry to trouble you.

 

[Sol]

Well whatever it is or was, i hope it irons itself out, hate to see such a beautiful plant go south. Peace Bro

 

[HemperFi]

Here are the other plants in the tent -- in the same soil.

 

[HemperFi]

That last pic is one plant -- you may be right about the light. I went looking for a light meter once -- didn't find it.

the flowers don't look too bad.

GONE SOUTH:

Well I think at this point you have the problem under control, azs you have flushed and got the PH under control again. The bad thing is that the damage is done and will not regenerate. But don't trim them leaves until they look like they are dying and are feeling crispy or have major brown patches.

As long as they have more green than brown then they are serving the plant. You will probably lose some amount of the harvest potential but she should pull through. From what you said, I suspect that you accidently doubled up on the nutes and shocked em, and threw the PH into a tail spin at the same time. I have done that before myself. That is why I always feed and water sober...I have a hard enough time trying to keep up with what I am doing, and remember what I have done, I don't need to be baked on top of that.
Green Mojo for yer girl bro be patient and watch the nutes and water.

 

[HemperFi]

thank you HP, made me feel better. I'll be more careful.

Sure shows that there some things going on during the dark period -- dramatic things -- Makes me wonder if I shouldn't change the lights in vedge to 18/6 and give them some down time as well.

 

[HemperFi]

20/4 sounds like a reasonable compromise. I only have the vedge space at 300w anyway, and they seem to be doing fine. I have decided to change up my feeding process. From now on I will not mix more than one gallon at a time. I will mix it the night before feeding, PH it before I feed, and do one plant at a time.

Wait a min Puff, How can they photosynthisize when it is dark and there are no photons? They can't be doing the same thing in the dark as they do in the light, can they?

 

[HemperFi]

or is it like kenetic energy -- they continue on until they run out of steam? I'm just trying to understand.

 

[HemperFi]

Is it some kind of momentem thing they already have going on that takes time to run down -- and then they stretch? How? I mean, if all the processes have been shut down, how do they stretch? that's growth -- do they grow in the dark? I have always thought plants needed light to grow. I'll meditate on this....

peace

I have another quote from this "pamphlet" written by the hydro guy. "Nutrient lockout is an accurate discription of the problems caused by over watering, not from the pH being out of range."

Makes a lot of sense to me.

I have read all the stickies, and much, much more. I have asked questions and argued with some folks, and I have thought deeply about this -- what I am loving is that it is a growing thing, lol, don't think the pun was intended. No one has all the answers. All the answers may be out there, but they have yet to be compiled. I love the adventure of growing, and I don't really mind a failure on ocassion. It's a learning process -- no matter how much you know -- you don't know it all...

 

[HemperFi]

Wow Puffin, that answers all my questions. I was really wondering about it, and you made it so simple. So, light or dark the plant is aware of it's existence? It is looking for light and stretching. Makes sense to me. thanks

 

[bho_expertz]

Just my 2 cents.

I never water when the lights go off. I always water when the lights go on. This because of RH and mold.
