Hello I have been having some problems with my plants. They have turned yellow, losing color looking almost neon, then ultimately turning brown and dying. I went to my local grow shop and had my water tested, the ppm was around 340-365 ph was 8.7. I was told that there was no real reason to use this water bc it was going to be too hard to control. So I bought a 200 gallon RO water system. Hooked it up to my 60 gallon container with the auto shut off valve on now Im using that water. Starting ppm is now (NO BS) 4-8 ph is 6.4-6.7, great stuff! Ive been using cal+mag with sensi bloom a+b, the leaves still kept getting worse, so snbow I am flushing with just cal+mag. Ofcourse this is based ALL on the fact that my grow shop told me I had cal mag deficiency. Using 3 gal pots with coco 1000watt hps system. Hand water using a wand with pump. Running temp is never over 77 degrees canopy level humidity 35-45%. Plenty of fans running circulating air, even have air conditioner, and on occasion use dry ice for short term CO2 boosts.PH water as needed. WTF IS GOING ON?????????????? plz help me
