I'm growing in Coco and I'm now starting my 6 week of veg. I've been keeping my e.c level on the lowish side. At the moment the feeding EC is 1.3-1.4 however my runoff EC is like .7 and .8 . My pH range between 5.7 and 6.0 . The plants looks well and no deficiencies could be seen. Are there any serious concerns about this low Ec run off.
For my grows I don't spend a lot of time with ec. I check ec run off maybe once a month to see if my salt levels are high and I need to flush. As for ppm I focus on what's going in and periodly check ppm run off. If I don't see a 100-150 drop in ppm from the intake then i see what ec run off is and depending on high or low if I'm over feeding or they aren't getting enough. This may not be the known correct way buts it how I do it. By no means am I remotely close to @Mr. Grow It level or knowledge, he would know the scientific correct method. Hope your grow keeps good and finishes great, good luck 👍
I'll add ec was great when indica satava were different, now with almost everything a cross hybrid the optimal ec for each strain I don't know if it really applies. But if you do have strait strain indicas tend to like ec ranges of 2.0 and higher while sativa's are normally 1.0 and tend to be light feeders. @Mr. Grow It, please correct me if my memory has failed and misstated something or everything lol.
Addition: when I said 100-150 ppm drop on run off that's not first run off, that's the tail end of run off.
Runoff pH or the pH of the water/nutrient solution before giving to your plants?
Has to go back through and read what I said, drinking watching sports and reading grow forums at same usually is bad combo 😂. My run off pH is usually a point below what I'm putting in for first half of grow, when that starts getting to low or to high I look for medium issues, possible flush needed ect. Ec is not something I use as most would, maybe once a month I check that using it looking for salt build up.
