Ok, two of my plants have been starting to show some light green spotting and the leaves with the spots have curled into a taco like shape. PH is right around 6.8 and nutes are at 770. I'm going to mix up a new batch of nutes today because I had a water spill with the draining and I'm now low on water in my res. That and I need to add two more buckets to my system.
This is getting worse and I can not find any pics similar to what is going on with my plants. I figured I would have at least had a few responses by now...
what kind of plant are those ? are they even cannabis ? better pics plzfill out stinkyattics trouble shooting form asap
Ok, I got a few more pics. I'll also describe my grow a little more...
It is hydro and I'm using AN sensi-grow at around 800 ppm. Water started out at about 50 ppm and is city water adjusted to around 6.5 to 6.8 PH before being added to the res.
On to the pics...
First pic is of my healthiest plant. Second pic is of one of it's lower leaves that is experiencing the same problem as some of the main leaves of the plant in pic three. Then some additional pics in hopes that it will help me, help you, help my babies. :jointsmile:
Im sure 6.8 is ment to be runoff for soil not hydro. hydro is ment by be at around 6.
Ah ha found it "You want around 6.0-6.5 for a soilless mix, or 6.3-6.8 for soil."
But that looks similar to what i had when i over neuted them only last week, flushed them through and there on their way getting better now :)
Hydroponics, set your pH to 5.8-6.0.
Is water splashing on those low leaves when the plants are being fed?
alright, I will be lowering the PH. I thought I had read that 6.5 to 6.8 was a good area to be in.
Now that you mention it, I do remember that at one point there was some water that got onto the leaves while I was messing around in there. I guess I didn't think it would harm them though. With the system running uninterrupted by me, there is no splashing going on though.
Even though the leaves only got wet one time, would they continue to get worse like they have been?
Nope, if water splashing is going to damage leaves it take a lot longer to leach out nutrients than just once.
Well then that shouldn't be the problem. I guess I will just change the PH once the lights come on tonight and hope for the best...
The problem appears to be getting worse still and has spread to other leaves on the plant. I really hope I can save it. It is one of my better plants that is growing right now.
