I have been having problems getting the runoff within range so I have been flushing with nutes ph,ed high and ec low to correct.
How do I fix my ph, ec issue and what is causing the yellow tips. I added the last three feed charts so that you may note the ec, ph in and out in regards to the amount.
I want to get to where I can only have 20% runoff and the ec/ph stays in proper range in waste. This is my first grow. I was up to 1.9 ec but dropped to 1.5 in order to get in range and raised ph for the same reason.
they look excellent. I wouldn't be worried about a little tip burn, it's fairly normal when doing what you are. excellent job on nailing the data points on your first grow!
I feed with an EC of 1.4 and a ph of 6.5 to try and get plants in proper output range (EC within .3 of input and PH in a suitable range for plant pickup of 5.5 to 6.5). I will do the same for todays feeding as yesterdays feeding outputs are still off but appears to be getting into range although its taking a little time. EC is now in range, PH in ongoing. Does Mycorrhizae cause ph output to be much lower than input? I only used it to transplant weeks ago.
