My first plant ended up being a male although useless I've grown an attachment to it. I flushed it this morning to check the ph of my soil this evening I found rust color blotches on fan leave, top grow looks unharmed was it a mistake in my flush method I just added 1.5 gallons to my pot and caught run off to test with my meter
Is that soil or cocoa? What is the pH? How much and what do you feed it? I doubt flushing it would do that unless something is wrong somewhere else.
Its a garden soil mix a little blood meal, top soil, I recently added a small amount of ground egg shells and even smaller amount of wood ash to a fresh bed top soil I added to base of the plant. Soil Ph was 6.9 its usually 7.2
I don't know if this is directly related to your issues but, that soil looks pretty dense. If at all possible, transplant it into a mix of pearlite and the soil to increase drainage.
Also, pub med published a study showing that male plants have almost as much active cannabinoids as females. Now, I realize this goes against just about everything people say but, these people have the equipment to actually test these things. I personally can't say it's true but, since you're growing a male it would be sweet if you could let it fully mature and make some hash out of the tops and, if they exist, sugar leaves and let us know how it goes I've always been curious about this
haha I was being serous dude....that medium looks like troll poop. good luck with your troll poop grow
