looks very similar to an issue I was having. pH swings caused my "rust" spots. I got a pH doser controller and the issue was completely eliminated. Mine had nothing to do with "CalMag"
I really like RDWC with the fallponics type setup (check out pahydroponics). Its very unforgiving and the first couple grows were very frustrating but if you stick with it and learn its pretty amazing.
This is my second summer growing and I'm realizing that mold will enviably be a factor. Is there anything you can spray on the buds themselves as they form and mature to combat/prevent it? BTW this will be my last summer growing, I can get enough September through April/May to just skip the...
How much mold do you think we have smoked before the legal markets? I personally snip out the moldy spots and throw them out but with the weather right now I'm thinking I'm going to have a lot of mold to deal with and I will probably try making edibles out of it.
My current pump is rated for 370gph and after you said something I checked the specs on the chiller and they recommend 200-315gph, specifically their 291 gph pump. So that could definitely be the cause of my lower performance. I haven't ordered the new pump yet so I will look into the DC pumps...
I have a 50 gal system with a chiller rated for 70 gal and it has to run non stop to keep the water at 70 when the chiller is set at 68. So if you do invest in a chiller make sure its big enough
I have the blue lab ph controller and really like it. I really had a hard time shelling out that much money but just couldn't stop my pH from crashing.
but I'm nowhere near retirement and I'm past the point in my life where I'm willing to work with other people ;) My bi-polar is pretty horrible. I can hardly tolerate my own company some days. I kid you not.
It's scary how well this describes me at this very moment
