i know that pick is 10 days to harvest and the fan leaves should be yellow, but there are not many left on the plant and the ones that are still there are shriveled and crispy. So at what point in the grow do you start loosing all you fan leaves, what are the symptoms you first see.
do you have a hood on that light?
maybe put something reflective on the pot that the plant is in to cool it down a little, the black will just absorb the heat and stunt root growth. Put a fan on em too
i would say add some hydrogen peroxide to your water to get some air to the roots, but not if you have the benneficial microbes, it will just kill the bacteria.... so maybe put an airstone in your water before using it to up the disolved oxygen levels in the water.
hang in there bro there are plenty of people on this site with way more knowlege than me, im sure well get to the bottom of it
