Thanks grey. I had a problem last grow when i sprayed with Baking Soda. I probably used too much. I think 1 tbl a quart instead of 1 tsp. Any how my whole garden was white from the residue. Sad but in retrospect, funny.
The runoff ppms was 1500. What i poured into the plant to check the PH was nutrients at 1500 ppm. So the samer thing came out the bottom as what went in. Correct me if i am wrong, but i thought that meant that there is no buildup of salts in the soil, or else it would have come out higher than what i was pouring for the test. I hope that makes sense. I am relatively new at all this so my explanations may be senseless.

ps. I may be new but i have experienced...mites..mildew...hermaphrodites...see ds...lockout.... and the list goes on. Hows that for a lot of experience ina short amount of time...I wont bore ya'll with the rest.

I think the cause of this is because i have not been adding calmag to the girls. I am in soil in 4 G pots. I have well water that is at 120-130 ppm. I am running Botanicare pro bloom soil, Karma, and sweet. They are about 3 weeks into bloom and this is what i am finding. Starting from the lower branches Leaf edges have brown small spots along them. The tips also have turned rusty/brownish on the bottom half Rating: 5
