so I got a newbie question. If there are fan leaves that are still quite green by the end of the flowering, you said it means they got too much nitrogen. What is the problem with getting too much Nitrogen?Yea by mid flowering you want the fan leaves to start turning yellow and by the end you want a good amount of the fan leaves dying off. If there still a healthy green by the time your looking to flush that means it probably got too much nitrogen during the flowering process.
I would assume, with 3-5 weeks left in the season, I would consider it to be in the 2nd half of flowering, and thereore little to no N...agree?The problem with too much nitrogen during the budding cycle is that N promotes leaf growth so do you want your plants energy to be put into the leaves or the buds? You do want some N during the first half of the flowering cycle but by the 2nd half it should be cut out if possible. It's not going to do any harm its just not where you want your plants efforts being directed if that makes sense.
You definitely don't want to water your plants everyday to flush them, this will cause root rot or a number of other problems. What you should do is to thoroughly water your plant (3-5x the normal amount you would water it) and then let it dry out. This could take anywhere from 3-7 days, depending on your soils water retention - you can test for this by sticking your finger deep into the soil to see if its still moist. Once its dried out, repeat the watering process again. Again, after it dries out, you should notice a lot of your fan leaves are yellow or yellowing. This is roughly when its ready to be taken down.so when flushing, do you flush out every day or as they need watering? Also if i have 5 to 7 gal. buckets, how much water? and last, do you ph your water when you flush?
