Rusty Look on Leaf

Well, I remixed new hydro at 6/3 and raised the light to 30 inches and they look a lot better this morning. Sorry about the no pics but we had heavy storms yesterday and I didn't get past my shop. I come to the conclusion that the hydro mix was too high and they were getting too much calcium. Now, it is common practice for me to flush the plant before changing hydro mixture. A 3 hr flush will flush out the old hydro and salts that damage the plant. Sometimes you have to go back to the basics and start over and that does not hurt the plant. As soon as they get the feeding they like they grow like " WILD WEED", YEEEE HAAAA!!!!! Thank you folks for the good input. Pics do help but not always needed-but makes it easier to diagnose. Has anyone here grow Medijuana, White Queen or White widow? I've grown 1 of them but not 2-Medi and White Queen- if anyone has grown these 2 and have some input please let me know, I could use a jump start to get these producing right. Besides, I keep 1 from each kind as mothers for clones after flowering for 2-3 weeks. HAPPY TRAILS!!!!!!!!!!
