Basically, I noticed what appeared to be a cal-mag def. in the browning of the leaf margins/veins, and flushed with pH'd water. 1 of the clones has picked right up, and is exhibiting new growth every day, but the other just won't grow at all, and I don't know what's going on. I'm flushing right now, so i'll be adding nutes again in the next couple of days. It's my first time from clones as well, so I don't know if i'm just being impatient. Will she pick up eventually?

I've treated them both exactly the same regarding nutes, light etc.

Here's the pics of the initial damage, but i'm more worried about the clone that won't grow, so if anyone has any suggestions, i'm all ears.

Wow - a whole day and not one single reply. Could it be because there isn't a darn thing wrong with your plants?

If you made those tips turn brown, it is most likely nute burn. However, those leaves are from the original cutting/clone and that damage could have been done two months ago when the stem was attached to the mother. Additionally, once a plant starts growing, the original leaves from the clone aren't a very good indicator of much of anything. Those leaves get a lot of abuse & stress during the cloning process and are prone to damage that is of no significance.

Your new growth looks good; your defs from cloning all seem to gone - seems to me like you're on the right track.

Enjoy your grow!

I beg to differ.
Here's the pics that should have went up in the original post, but i've only managed to get the camera tonight.

Looks like root-rot for the smaller of the clones(?), and the bigger, still growing one does, in fact, have burned tips on the new growth. It has been caught and flushed.

It's flushing as we speak, so i'll be adding nutes @ 0.8 tomorrow and crossing my fingers.

The other clone is properly fucked though. Check the difference in size/new growth:

Brown roots like that looks like root rot like you suggested. Maybe try 1 teaspoon per day 3% hydrogen peroxide from the drug store per gallon of water. Or, 2 teaspoons twice a week. Treat all your plants...

After the clones have rooted, particularly ones like your yellowing plant, I like to remove the old, damaged leaves (like the ones that are really yellow and really droopy). It lets the plant put its energy into new growth.

You might want to drop your pH just a tad to make N more available, and do like Buzz said with the H2O2.

The problem shows overwatering causing N lockout....that's why they are droopy and yellow...do you have adequate air pumping into those buckets? More the better. Most peeps run two separate pumps that both feed the buckets. Besides the extra airflow, if one pump fails the other can keep things going until you fix it. If your pumps fail your plants will die in a matter of hours sitting in stagnant water.

Don't listen to buzz, he is a well known poser who has never grown a plant. He has been banned many times for his shit. You can search his name/past posts and see for yourself. Also search blackvelevt and sproutco and you will learn all you need to know about this poser.

if the rotten root cut is of value, simple toss into soil and at least you can still take cuts in time

Funny you say that actually - I was gonna stick it in Coco and do just that! Great minds think alike eh?

And HeadyPete - that's not the problem mate, though thanks for the suggestion. All 4 buckets are running form the same pump, and have the same size airstones, and as you can see from my other plants, the buckets are plenty oxygenated from the stones.






Honestly, regardless of what Buzz says, I reckon that it's root-rot starving the roots of oxygen, and creating nute uptake issues.

No new root growth has occurred since this problem started, and no new foliage growth either.

Cheers for all the input - if anyone has any advice though, i'm all ears. Looks like re-potting into coir/hempy/soil may be my only hope though.

 

[HeadyPete]

If you have proper aeration you wouldn't get root rot. What caused the rot in the first place? Is the stone plugged? Is it putting out the same bubble action as the others?

There has to be a problem with your system if everything else is identical.

If you take a plant that started in hydro and try to put it in soil/soiless, you will have problems. The roots have developed thick, to uptake lots of water, whereas roots for soil develop root hairs that are thin and feathery to find the moisture. Your hydro roots may not be too good at taking up water from coco.

Honestly mate - I have no idea what could have caused it in the first place except maybe high temps in the res. Upon secondary reflection about the situation, this clone is actually under the 'hot-spot' of the HID, so maybe that's shot the temps up too far and encouraged the rot - if it is, in fact, root-rot. Other than that, I can't really say what might have caused this problem. The stone is putting out the same aeration as the others, and it's not clogged in any way.

 

[HeadyPete]

I think you are onto something there as higher water temps hold less oxygen and could definitely lead to root rot.

The symptoms definitely exhibit that of root problems - usually soggy soil will do that and it is the same issue at the core, inadequate oxygen to the roots.

Good luck and I hope she recovers. Probably will.
