I am at 850ppm 5th week of flowering EC x 500 (purple diesel grow)
Nice grow, I heard OG Kush was a bit hard to grow. It says that in the oaksterdam catalog. I would love to check out your progress Good Luck!
My style when it comes to TDS:
I check the TDS before the watering and again after.
Lets say my TDS before is 850 and after its 800. That is quite a big drop so I would raise my nutes. So the next day say before the watering is 900 then I check after and its 880-890. I leave it. I only want a small drop.
lets say before its 900 then after 920. My TDS is too high.
My plants seem to do great when there is a small drop to no drop in TDS after watering. I grow in rockwool and I water once a day (ebb and flow). This has always worked great for me. This along with what the plants say. Yet what they tell me is they like my style.
