Hi everyone today it was the second watering with nutes and I used a TDs meter to check the ppm of runoff…my tap water was 116 after siting 30 hours after I added the nutes went to 350 and the runoff was 597 plant 1 500 plant 2 552 plant 3 620 plant 4
Can someone explain me what that means please?First time grower here and a bit confused with the feeding 
I will definitely grow same strain next time…each plant is different but I’m treating them in the same way as I don’t know how to read plants yet…and the result is not equal propably I will have to lst one of them and I really didn’t want to do that first time but it’s getting taller than the others so any tips on lst will be much appreciated
Cheers guys
