Did you check the online schedule and start following it?

What does the new growth look like? Old leaves are old news, and they don't heal. They'll keep fading.

How are you testing runoff ph? If you're not using a ph pen, likely your numbers are off.

You'll want to keep the ingoing water between 6.3 and 6.8. I aim for the upper-end, (6.8ish) since adding nutrients drops it further.

6.1 ph is a tad low, not a tad high. (unless you're in coco or running hydro)

Like I already mentioned, it might well be overwatering. Provide pix, and perhaps we can see...
Rusty Trichome Reviewed by Rusty Trichome on . Yellowing leaves in veg I've read a lot about the yellowing and browning of leaves and what it could be. But am still not sure with my situation. They started just at the bottom and a couple of small leaves have died. But on a couple of plants the yellowing has seemed to spread and brown spots have developed. I'm almost 4 weeks in veg. I'm leaning towards too high ph, but I'm also worried about nutrient levels. I've been going a little above 7.0, at most 7.5. I thought it was good to have right on 7, but now I'm Rating: 5
