Your plants are expressing an Mg deficit, as long as the ph remains low (I'm assuming but pics seem to bear this out) your girls will be lacking in nutrient uptake of Mg.
I'm assuming your ph is low and Mg is being locked out. Do you monitor ph in any way. Is gold label supposed to be an organic substrate?
Yes but it's via taking a small vial and adding droplets. Probably not the best way. I figure my ph is about 6 using the colour chart ?? I have ph pal plus somewhere guess I should find it ?? How do you mean substrate ?
Substrate and medium are the same. If it read around 6 it's probably lower than that. Is your medium supposed to be organic?
If it is indeed magnesium def (my first thought as well) then epsom salt as a foliar is the fastest remedy at .5-2tsp per gallon.
Hi plantin seeds, how long would that take to remedy and what if it's not a mag def. could the ph 6 cause this ?? Thanks
I would bet Poke's life on it being Mg deficit. http://hydro-heaven.com/yahoo_site_admin/assets/images/ph_Chart_3.208114926_std.gif
Look at this chart for a comprehensive understanding. epsom salt is magnesium sulfate. You can buy it almost anywhere. You could say its organic.
