New Grower Bottom leaves yellowing and dying in early flowering stages

[some_guy_]

Hey guys, first time grower.
My plants are in early flower stages but the bottom leaves are yellowing and dying.

Any tips?
Growing in Coco, pH is 5.8, GH nutes, EC ppm is 400 (side question, is that too low? Can I up my nutes?)

Thanks everyone.

How strong should your nutrient solution be for cannabis? The strength should be determined by EC or PPM. We walk you through how to set EC/PPM targets.

Also, looks like N def. FWIW. IMHO, etc

Yeah, it probably is a bit too low to feed 0.8 EC to a flowering plant. Are you checking runoff EC? If you do and it's 0.1 EC or more lower than input EC, you know you can up the nutes to 0.9 or even 1.0 EC. If it's the same EC or higher EC than input EC, you shouldn't up the nutes but make sure pH is in proper range. I'd suggest you bump pH to at least 6.0.

Thanks everyone. I tripled the nutes and the plants looked heaps better. I switched to House and Garden Coco A+B a few days ago, and the plants look even better
