I am growing some plants in Poly grow medium if you have not seen this stuff it is white fluffy like dense pillow stuffing I am just doing a test with it. Everything has been going great and then boom the temp here changed a little bit and massive green algea I think I have it under control dropped the temp, and covered the poly a bit better it was a bit exposed to the light, but it was amazing how fast it happened. I will add some pictures of it this weekend. Also getting a bit of curling on the leaves and some yellow, but it is not crazy so I flushed and now I am way down on the nuts for a few days. One of the thing is that the roots have gotten huge and they are down in the water, so they are drinking all the time I am this weekend going to fix it so I tell them when to drink again I hope this will also help with nut burning.
