Your ph down bottle, Read and find out what type of acid it is?
What is your tap water ph and PPM?>
I can see why you have had nitrogen burn marks. cal-mag, part 1+2 also carry nitrogen.
how much of what bottles did you give last feeding?
170 out of the tap is ok, you need to drop the calmag and up your flower nuits up to around 650ppm, this includes the 170 for your tap water. PH your water to 6.0 with the PH Down, and you should be sorted. Don't let your medium dry out.
i use promix hp, tap water ph is at 7.02I'm shocked to say that my acid doesn't say what kind it is.
Tap water is 7.1-7.5 pH and 160-180 ppm
Fertilizer solution would look like this:
- 1.5 L water
- 4 ml/L of Part II and Part III
- 4 mL/g of CalMag
- pH adjusted for range of 5.8 to 6.4
Thanks @PK1. I"m doing pretty much all of that, with the exception being i've let my pH of water or fertilizer drop as low as 5.8. Based on your comments above, is it fair to say your treating my medium as being "soil"? Many seem to suggest that a medium based on being upwards of 2/3 pro mix as being a soilless medium. Sorry to keep harping on this, but this was one of my key questions in this thread....i use promix hp, tap water ph is at 7.02
When i add my nutrients my water ph drops to 6.4
I don't ph adjust because promix adjusts the ph to 6. Slurry test results will show that

What you need to find out is tap water ph, once nutrients added, measure ph and then adjust ph to 6.3
5.8 is for coco and hydro. If the ph of water after nutrient is around 6 to 6.5 than just leave it and don't ph adjust. However, if your ph jumps up after nutrients than adjust ph to 6-6.3
@PK1, can I ask, when you feed, how do you determine you fluid (water and fertilizer) volume? At this stage, i'm typically watering about 2.5 liters of water per plant. Would you fertilize at the same volume? Thanks in advance!i use promix hp, tap water ph is at 7.02

i determine it by looking how green my plant is and what my ppm levels are. my tap water has 22ppm
seedling 22 - 300
Veg 300 to 600
flower 600 to 800/900/1000 depending on your strain.
as far as how much water, i water until i get run off. However, my watering takes about 1 hour. Thats a combination of 1 min watering and 15 min of waiting lol.
having couple joint's rolled up helps. during the brake light one up and go through each plant to see what its showing you.YOur much more patient than I am pal. I trust your special ladies appreciate the efforts
