My Ph was a lil low 6.2 6.3 as for bugs i dont see any thru my 40x loop any where! I think its the low ph and maybe cal deff.!! will see (fingers crossed) Thanks Milk:thumbs:

That looks like cal/mag. Your pH is only off by a small amount and I'm not seeing any signs of lockout, so don't think it's a pH related issue. They are getting to the age where a potential cal/mag deficiency usually show up. Next feed I would give them some cal/mag supplement or some epsom salts and molasses.

Thanks Muddy and Milk !! So i gave them a dose of epsom and molasses,hopfully that will take care of it! Thanks guys!

I think a good foliage spray with Epson salt at lights out time would be beneficial!
