Yellowing Leaves, I'm confused

Ron

Hi,

Sorry in advance for the long post but I'm worried I'm going to lose my 2 girls!

I've got a couple of plants, grown in soil, that are slowly dieing from the bottom up. I've attached some pictures showing leaves in different stages of turning.

1. Starts with the green veins and yellow leafs.
2. moves to all yellow leafs.
3. finally the edges turn and the leaves are brown and crispy.

This has been going on for weeks now and seems to be getting worse as time goes on. First I tried a flush with RO water then some tomato food with micro nutrients I had at 75% strength 18-19-30, no joy. I then tried transplanting about 9 days ago and it had no effect (the plants were somewhat root bound). My regular fertilizer is a hydroponics mix ( 2 parts, 1-2-5 and 2-0-0) that I'm trying with soil. All of my basil, sage, rosemary love it and it does list many micro nutrients so I suspect it is ok. The pH is around 6.5 or so ... hard to get super accurate with the ph testing drops.

Is this a Mg issue?

Thanks for lookin'
R.

Is it just those few leaves or is it more? They do naturally die off. The plant looks fine other than those leaves. Is this your only baby or do you have others this is happening to as well? Have to have more experianced heads than me take a look Ron.

Hi jangel,

Thanks for the quick reply. Both plants look about the same. They have been vegging for just over 8 weeks now. I suspect it is time to start the flowering cycle but I'm not sure as this is my first grow and I want to make sure they are healthy before I commit to flowering them. These are northern lights #5 (indica) if that matters.

Thanks,
R.

You never said what kind of soil you have them in. Is there perlite in it and is it airy and light? It could be something with the roots if transplanting it did not help. I need the kind of soil they are in. Also, my plants look something like that when they are root bound. you say you just transplanted it. I have to almost do it every 2 weeks to keep up with the root growth.

I have to say I agree with jangel that the rest of the plant looks fine and you may be correct in needing to start them flowering.

Hi Ron,

I would not think that those leaves are going to recover, and since they offer no further benefit to the plant they should be removed. The rest of the plant appears healthy, and you don't need it spending it's energy trying to save leaves that are already toast.

I'm with Jangel...move it to flower and let her do her thing..it's time!

The base for the soil is a generic ready to use planting mix (with no fertilizer). One pot has around 40% perlite - 60% generic mix. The other has 40% peatmoss - 60% generic mix. I figured I was feeding them with the hydroponics solution so I didn't need to worry about top quality soil. Also I have about 1 inch of wash gravel in the bottom of the pot. I don't think I've got issues with root rot as the soil is quite airy and I do let them dry out between waterings. You transplant every 2 weeks, wow are you keen! These plants are 8 weeks old and have been transplanted twice.

Thanks for the advice,
R.

Sounds good! I'll switch them over to a flower cycle and let 'er go!

Cheers,
R.

PS. Until recently I was removing the yellowing leaves, I left these so I could make some decent pictures of my "problem" to post here.

With so many leaves it is natural to get some dieing off as they grow. They have to. Looks like all the other leaves are nice and deep green. I have two grocery bags of leaves off my plants, that just natually die off. Maybe they get rubbed, or there is a branch coming out there. If they are healthy, save the fan leaves but if they don't serve any purpose, Lop off their heads! ISO is right.

And you have to keep feeding them with that soil. .....we have to talk my friend.

There is no nutrition in that soil so the roots are going to get hungry and the leaves die off very quickly. My plants do it cause they use all the nutes I mix into the soil up, and that tells me it needs repotting. I look at the bottoms and sure enough, roots coming out of the holes. So don't stop feeding them. Also, try doing a ph test next time you water well. Save the last bit of runnoff out of the plant and test that. It will tell you what your soil ph is and that could also be a problem.

Just prune her back and set her to flower. Take clones first.

peace.
