What is this fading on the leaf and the edges folding up a little? My guess is either the light was too close or lack of water possibly? It better not have anything to do with those godforsaken russet mites
All they have had is 2 teaspoons a gallon of tappin roots. Just fed maxsea last night only 1tsp maxsea and 1 tsp tappin roots per gallon. I also dont see burns on the tips
Dude arent you the guy from the outdoor thread this summer that was spraying forbid on budding plants because you had the hemp russett mite guess what get out your scope you have it again.If you are interested in getting rid of it let me know although you ignored my addvice this summer.
I agree that it's a magnesium deficiency. Try Botanicare's Cal-Mag Plus or some other brand or simply dissolve a small amount of epsom salts in your water.
Check the pH at your root level. If it is too low below 6.0 or so in soil it'll cause a magnesium lockout. If that's the case increasing magnesium won't fix the problem.
