Well folks, thanks for the encouragement! I am going to over come this deficiency one way or another. If anyone has any suggestions I am all ears.
 
I was thinking it was a calcium deficiency, and you were suspecting magnesium, so have you tried a Calcium Magnesium supplement? You know, the old "2 birds with one stone" thing?
 
You need calmag supplement under leds, quite a lot too!
 
I've got 200% of the recommended dose of Magical (Mg & Cal) in the res. Up until the deficiency showed I had 100% Magical in the res. I've raised the PH to 6.0 to see if it's a Mg deficiency. If I understand the correlation between PH and Mg absorption. I'll let you know. Thanks!
 
Tech Support tells me to reduce my photo period to 18/6 and do not top feed while the lights are out. So I've adjusted my timers and we'll see how it goes. I am still holding the PH at 6.0. I would have liked to have tried each of these adjustments independently to determine what the actual issue is but it's just time to clear it up so I'm firing both barrels at once.
 
Yea man. Ive been rolling with 18/6 so far. Seems to be the happy medium. You got this man. The process is refining you into a more experienced grower.
:bump::smile:
 
Thanks guys, I'll get it sooner or later. Cheers
 
It's got to be a magnesium deficiency. I am using the reference thaGreenBandit gave me and the Mg deficiency is a perfect match (http://www.growweedeasy.com/magnesium-deficiency-cannabis). The plants are exhibiting all of the symptoms. I've had a ton of MgCal and all of the other additives in the res. The only thing I can think of is that the PH is still too low.
