Any ideas on this growth?

[Speed of green]

Have some new strains in veg that I've never grown, Blackwater OG and Sweetdream.

There is some new growth that looks odd. Its affecting both of the new strains.

feed: jacks+calnit @1.2ec
ph:5.8
Medium: promix HP

I foliar fed some fulvic 3g/gal & epsom salt @1tsp/gallon about five days ago, they were a little yellow from clone, after this foliar they looked much greener.


Ive had pretty good success with jacks in the past using equal parts by volume and R/O water.

I feel like this issue may be from me not using R/O water, as I've just moved and haven't had time to set up my R/O yet.

Any ideas? Thanks!

First thing is to raise the pH. Promix pH is best around 6.5-6.8. Your 5.8 pH is for hydroponics.

Mix some nutrients at 1/4 strength and pH to 6.8 and flush those plants out and see if they improve.

Yeah I'm going to re-calibrate my meter and test the runoff as well. I was reading about TMV Tobacco leaf mosaic virus. Freaking myself out... hopefully its something simple like PH.
