What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)Add.27,silica,zone,A+B
What is the TDS/EC/PPM you are using1.5 EC
What is the pH of the "Tank"?Fluctuate between 5.8 and 6.0
How often are you testing your pH/PPM/EC/TDS?Every feed
Are you sure your calibration is correct on your equipment?Yes
When was your last watering?2 days ago
What is your water temps?22Deg C
When was your last feeding change? (ie. grow-bloom-micro-additional)1 week ago

If using tap water, what is the ppm/EC/TDS of the water right out of the tap?tested at pool shop at 14ppm
If using RO,Distilled,mineral water, what is the ppm/EC/TDS without any additives?
Are you using water from a water softener?No
Has plant been recently pruned, cloned off of or pinched Not since veg
Have any pest chemicals been used? If so, What and When?
Are plant's infected with pest's Yes, Kill-a-mite late veg
I have been having some trouble with my last grow and now i'm seeing the same thing happening again
I have searched through the sticky and it looks like a Potassium def. and also cal/mag
I always water with 20% runoff and i'm currently watering every second day letting the top of the coco dry slightly
EC going in is 1.5 and runoff is 1.5 so i dont think its lockout
I have been treating with Cyco Dr.Repair and thought i was seeing improvement but in the last 2 days its getting worse
Here are a couple pics
Any help or advise would be appreciated
Thanks in Advance
