PPM

Wscook07started grow question 3 years ago

when I mix my nutrients my PPM is only 120, When topping off my res. the PPM is at 40 & Drops to under 20 before topping off again. I have already burnt my plants a week ago but is that enough Nutrients? I cut it from 2 ml/ltr to .5 ml/ltr because of the burn (Advanced Nutrients)

Normally if you are seeing the EC drop the plants are taking more food than water which is telling you to increase the feed a touch. I tend to step up in small increments until I see the ECppm sit pretty stable. If I am feeling brave i increase the ppm until I see a touch of tip burn then back off a touch to insure I am giving them the max they can handle. Some people leave the ppm when they see a touch of tip burn and leave it there and actually call it ‘a perfect burn’. I tend to find in this game less is actually more👍

DWC PPM First feed I used rainwater with ppm of 15-18 and mixed 8 gallons with 18 ml of GHE Bloom, Gro and Micro with 4 ml of CalMag. Both buckets have new PPM of 350-390. Is that too aggressive for day 9? Or can I push more? New to DWC and growing and hoping for some applied knowledge. Thanks

Flush duration in DWC Okay, so here's the deal. A lot of people say that flushing should take a week or two. BUT flushing DWC could take only as little as 2 days. Is that true or does the medium really not matter at all? THX :)

Can coco loco soil use liquid nutrients? Or does it not need it?If I’m using Fox Farm Coco Loco soil, do I need to add nutrients? I’ve read somewhere that if I’m using coco noir, I might be better off using hydroponic nutrients? I purchased the fox farm liquid nutrient trio soil formula, but haven’t used it yet since I’m not sure.
