ok wut can be causing this, I pray it aint spider mites

Ok this problem has been progressing and I thought it was MG def but the food has plenty. I just hope it aint spider mites.

first look could be mites. Flip the leaves and look for little black specs then poke one and see if it moves

how are your growing hydro soil aero?

Organic soil

Looks like it could be a calcium/ph problem. It does not look like a spider mite problem to me

take a look under the leaves first as spider mite damage looks very similar to this... what is your water ph as it goes in and what is the ph of the water run off?

hers a link to see some dficiency damages.. http://www.onlinepot.org/grow/PHfluctuationsornutrients3.htm

unfortunatley I do not know my ph I have a meter but I dont believe its calibrated..How can you tell if you Ph tester is calibrated. it tells me to calibrate it at 4 7 10 and someone told me i had to buy calibrating solution

yeah that the correct way to do it and the solution will cost about $8 to get just get 4 and 7 and your good.Dunk it in the 4 and it shoulkd read 4 if not then use the adjustment screw to make it say 4 then do the same in the 7 solution

thanks so much filthyfletch is this solution sold at homedepot or am I'm have to go to the hydrostore

ok I check the plant i didnt see any black spots or any other type of pest, so im going to do some more research to try to see if I can firgure this out, all my other plants are doing fine and the food i give it states that it will not change the PH at all. how true that is im not sure..

ok if no mites the next way to go is finding the ph..the calibration solution can be found at most pool or spa stores.Ebay has it also and might find it at some nursery or pond supply stores

You can get pH up and down at home depot, but I don't think they sell the 4 or 7 solution for calibration at home depot, that would be a pool/spa or grow shop.

thanks guys I was wondering where in the hell you get that soution from after looking at the abuse chart it could be Mn def cause by to much MG, this problem only occurs at the top of the plant so Im goign to do a flush and get that solution
