Plants are starting to get mad

[McSmokin]

What do you guys think, pH issue? Im growing 60/40 coco/perlite mix. Feeding about 940 ppms at around 6.0 pH once a day. Also foliar feeding as soon as lights go out with a few drops of seaweed extract per 12 oz of RO water. Its mostly effecting only one strain, as I have three plants/two strains going. If it is pH, do I just raise it next feed tomorrow and go from there?

I've heard horror stories of people flushing their coco and getting all kinds of nute lockouts and other problems. Coco peoples, help a brother out?

Peace.

If I'm not mistaking does coco naturally lower the Ph of the substrate. Don't quote me on that but check some info around this site regarding coco. If this is the case just raise your mixes Ph slightly to compensate. All the best. Figured I'd leave a reply since I'm sure your anxiously waiting one.. Sorry I couldn't be more specific, but the info is here at
