Hello all, I have enjoyed reading your 1000s of posts over the last few months during my first grow. You are all incredibly helpful but I have finally come up with a question I couldn't find an answer for.

I have been growing in FoxFarm Light Warrior since the seeds popped and they are almost ready to harvest. I chose this medium because of reading about how some soils are too hot for autoflowers so at the store I asked the guy for a light soil, he said this stuff was good and I recognized the name from posts on here so I bought it. I have been PH'ing the water after adding General Hydoponics Floranova nutes(grow/bloom depending on stage) with a Hanna multimeter. I assume the meter is decent since it was about $200.00 average internet price and someone recommended it here. I store it properly in the solution and calibrate it. I have been keeping the temperatures in the lower 70s and the humidity about 30%(ranges from 25-40% but usually about 30). I was using a tea from the local hydro store but it gets stinky too fast for my uses so I recently started using Great White Mycorrhizae once a week. The water I use is tap water that has sat in an open 2.5g container with a fish tank air stone running for 48 hours before use. I have not seen any evidence of bugs, mold, or anything else looking wrong from the outside.

So, on to my actual question :) Should I have been treating Light Warrior like a soil-less mediums such as Coco or Hydro and been PH'ing to 5.8? I have been PH testing the water and runoff to 6.5 every time using the General Hydroponics ph control kit but using my Hanna meter not the drops in a tube. I have had ups and downs all over the place on leaves getting spots/curling/bigger bloches and read the ph charts then looked at the pictures of sick plants but never came up with anything substantial since the issue was so inconsistent where my feeding/lighting/temperature habits were not. The plants never died and the one I am cutting this week looks like it will produce just fine(first grow so I don't know for sure but guessing 1.5-2oz) but just looks like its been through a war compared to stuff I see on here. This was a variety pack of fem/auto seeds so the four plants are all different but had similar issues at seemingly random times.

Thanks much for any input you have.
 
Yeah Light Warrior is a soil-less mix, you're right pHing at 5.8.. however in full bloom the pH should be higher around 6.0 as phosphorus is key in bloom and the lower pH affects the uptake. As far as the issues you've had, you can help by watering more and getting more runoff. The chem nutes leave a lot of salts in the medium and that causes issues.
 
Thanks Jayar, I'm not sure why but I didn't even think of it until today when I read the post about using coco coir as a medium and wondered about my own. I will move my PH down to 6.0 from 6.5 since they are all in full bloom, I also just started trying to get more runoff yesterday for the salt reasons you mentioned(another thing I learned from reading about coco that wasn't as big a deal in soil) so that will probably help with the end of the bloom.

Next try will be four of the same auto seeds in better pots(air-pot vs walmart pot) and I am thinking of using coco this time with a proper PH of 5.8 and more runoff during feeds to hopefully produce nice green plants like you all.
 
Sounds good bro. Lol thats funny I changed from light warrior to canna coco and I'm loving it.
