pete2, unless you kill either the root structure or all the growth terminals, it will continue to heal and grow. You could accidentally split your main stock down the middle to the ground, put it back together and tape it up. As long as there's no infection it would likely mend then continue growing. Plants want to live....especially WEEDS!
Best not to ask how/why I know that, lol.
In flower? I wasn't aware we were talking in flower. If I'm training I'll stop at least 1-2 weeks before flower. After it starts flowering I'll pinch popcorn sites, and that's about it.
thankssince you've bent that thing all over i can't tell where on the plant the problem is occurring. Yea i know i'm trying to learn hst. Guess i need to practice some more.it is my first time.
Are the affected leaves newer or older or all over? Obviously older leaves would be 'lower' on the plant.
Mostly in the middel of the plant.i saw tonight that only 3 of the plants have spots on them.
What are the new growth sites doing? Do they look normal or are they starting to twist funny? Any discoloring other than a normal light green color?new growth looks small but fine in color
how do the roots look? Nice and white, browning in areas, browning all over? I changed the water in them tonight am only going to use plain ph balance water for a few days.when i took the air line out it had some slimey stuff on it
my roots have some of that on them as well,the inside of the buckets did not have anything in them. Don't figure
what water are you using? City tap, well, ro...other?purified from wal-mart
what is your target ph? At 6.0 lately been checking every day
what nutes and additives have you used and in what quantity?dyna-gro vegetation bottle says to use 1 to 3 teaspoons per gal.i use 2 teaspoons per gal.the cal supplement says 1 teaspoon per gal so that is what i put in each one
answer those and i might be able to diagnose the plant/system rather than a picture.
If it's spider mites you should be able to see them. Mostly on the under side of the leaves, sometimes on the underside of stems. If you have a magnifying glass, jewelers loupe or other similar magnifying device, you should be able to spot them. If you see them, treat the whole plant with your choice of treatment.i looked at them tonight with a magnifying glass best i saw a few white and black spots.like i said these spots are only on 3 of the plants
it certainly looks like calcium deficiency to me, but saying that you added more and it seems to be worsening makes me think in another direction.sorry,but that is not what i said.what i said was that i thought they had a calcium deficiency and i put a supplement in their water.a few days later i started seeing the spots.
It's possible you either have an overabundance of ca or n. Too much of either one will affect k uptake. While your pics don't look spot on for k lockout, sometimes plants have multiple issues expressing themselves and makes diagnosis harder. So to answer your question, can adding more ca hurt things, yes, it could.i didn't add anymore,i took it all out.i didn't see any mites and like i said there is 1 plant that don't look like the rest.i do appreciate the help and advice
now that's an out of the box theory mind you. Ca toxicity is pretty rare.
Another idea is too much k can look like a ca deficiency. Don't know what k is.please explain
right now i'm thinking there is a ca and k related problem, in one way or another
my recommendation (assuming you don't find the spider mites) is to flush and change your nute solution, cleaning the system in the process. Start with your 'basic' nute recipe at 1/2-3/4 your last strength. Leave out the fancy additives. If you're using a 2 part nute system, just give it the 2 parts. If you're using a seaweed micro nutrient or something, that should be fine too, just start at 1/2-3/4 strength. Make sure your ph is right on with the nute manufacturer recommendation.....then observe. Check the ph as often as possible to make sure it's not swinging. Does the plant start getting better within a week? Look to the new growth to tell you, but also watch the old leaves. They all have a story to tell. The dying should stop and new growth will be vigorous. Damaged leaves will not get better, so if they are damaged 50% or more, or have yellowed go ahead and remove them.
Many will tell you that adding more of this or that product or fert is the thing to do. I say you run a higher risk of compounding the problem. This is chemistry which most don't understand. 9 times out of 10 we are loving them to death in some way and don't understand how/why. Stop, breathe and get back to basics. Answer the above questions and we'll see if we can find the real problem.
If I said my girls were in flower it was a mistake.They are about 48 days old and are still in veg
silica is nice. I use it. recommended. but yeaaa... you need to consider and check how high your PPM will be with the additional supplement.
Why do you have slime my friend? You need a better air pump. I should have gotten the slime but I avoided it but keeping my DO at max

Here is a pic of the roots and the slime.All the roots do not have the slime on them,just where the brown spots are.The inside of the buckets didn't have the slime in them either.I just found it on the air line inside the buckets and a little bit on the roots.It's started a few weeks ago. How long would it take to kill the plants if it is root rot? Thanks again for the help.Forget I mentioned H2O2. You might want to get something like Hydroguard, Voodoo Juice or Great White. Hydroguard being the most affordable. Hydro stores should carry something, or Amazon sells it too. They ad beneficial bacteria that help fight root related diseases. If your roots and slime look brown you've got root rot. You need to increase the dissolved oxygen in your buckets, maybe lower the temp too. Think I would clean each bucket with a chlorine or bleach solution, replace the air stones and give each bucket more air.
The damaged roots will not heal. You will need to watch for new white growth to know when they start recovering. Hopefully they do recover. If you can upload a pic of the roots that would help.
Edit: I had just misunderstood the timeline of events is all. When you noticed the problem first, when and how much/often you added the cal/mag. Moot point and water under the bridge. If your telling me your roots and slime are brown, then your nutes and cal/mag are not the problem.
All good
