2 different reservoirs , I'm thinking I need some cal mag. It's just a few leaves .I'm also having ph fluctuation. The small tips that are brown in pic 2 has a ppm of 850 so I don't think it's nute burn. Any ideas?
Saw that too but it's just the top leaves of 3 places. I'm gonna do a flush tomorrow just to be sure. And back off the nutes. I'm thinking calcium because I'm keeping ph lo for flowering 5.6 and thats out of range for uptake of calcium I think? >6.4 . That's off the top of my head so may be wrong .
My feeding chart says I should be at 1400 ppm and I'm at 850. So ?
All our water is from the aquifer and with this rain I wonder if the natural nutes in the water have changed that drastically . The ph has for sure.
Thanks keep your fingers crossed.
Did a res change and went to half nutes. Also a complete newbie mistake, my ph meter was off needed calibration. Cal mag comes tomorrow and I will add that. Just when you think you got it, something comes in and blows your mind.
