How often do you water? How often with nutes?

Hi..
I have faced this same problem before.. It shows on the high grade strains or hybrids that I purchase online..but never on the natural strains. It never affected the plant or the harvest. I never did nothing about it and kept my regular schedules

Chairroller, we haven't determined the problem yet. We haven't even collected data. If you somehow know what the cause of the problem is, please name it.

Please, OP, if you can provide more data on your grow. Water frequency, feeding freq., water pH.

Sorry I couldn't find photos of this in my files..
When you analyze the leaf, and see that the discoloration shows only on the half of it.. that is related to the genes of the plant and not the nutrients or anything that the grower might intervene in.. As I said, this happens to genetically modified strains and not the natural species.. I wouldn't worry

Well, I've never seen genetics do that before. Full color change on half a leaf yes, but splotches are new to me. And only a couple have it just on half in those photos.

Not saying you're wrong, just doesn't look genetic to me.

I have seen that weird pattern when the PH was off. It disappeared within a few days after the PH was adjusted.

The genetics thing, I don't know enough to say it's wrong so I'm hesitant to give more advice.

Check your soil pH first, but yeah, you'd flush with pH'd water.

If genetics never entered the equation, that's probably what I'd have had you do, in the end.

Click to expand...

I grow in coco so I flushed it with PH-adjusted water. I just checked my notes on that incident and the spots occured when my PH was low. I agree with TrimothLeary: check your ph and flush with PH'd water.

Please let us know if it helps.

You could check early runoff to get approx. current soil pH.

You can also buy NPK and pH soil test kits. Not the easiest to read but if it's way high or low you should know.

Typically 3x your container size is suitable.

BTW, you don't need to pH all that water.

Pour the 3x container size water first. Flush.

Then just mix up to 1/2 dose nutes and pH and pour that in. Feed.

Flush and feed! Like rebooting a PC.

Should take care of it. Assuming it's not genetic. I wouldn't think so, but I have about 9 months experience from my first seed, so WTF do I know?

The point of the actual flush is to clear out nutrients in the medium. That water won't be there long. Because you're gonna pour pH'd nutrient water in right after.

Feel free to ph all of it. Can probably only help.
