Did a res change today. I used 5 gallons of distilled water and about 8 gallons of bubbled tap water. PH to 5.8. After adding nutes it=t was 5.6, a bit low, but I'll give it a day to see if it rises a bit, and I'm out of PH up anyway. Added 490 ppms of Maxigrow. Will add more in a couple days, after ph stabilizes, to bring it back to 600 ppms. Hoping this eliminates the problems for now till I can afford the RO unit. I'm watering all my soil plants with the distilled water also, hoping I can save some of them. My Durrty Cheese just started to flower when the same problems struck it also, hoping I can save them! I'd really like to see them bud! Same damn thing with my Durrty Dragon x Blueberry Headband, they got some nice size to them then went to hell with the yellowing and burnt edges on the leaves. I didn't get many seeds from that cross, so hoping that I've really found the cause of all this.
