Hello athirdpath. I'm new to coco, first time grower as well (which I guess makes me new to everything, not just coco LOL), so I am learning a TON about it.
When was the last time you flushed?

Also...check the chart I've attached. Pay close attention to the right side of it...that's where you and I live. I water mine with 5.1 PH water, and let it drift up going through the whole spectrum. I'm not saying "DO THIS", I'm just saying that's what I've been doing and my plants are looking very nice being in the 7th week of flower.
