Ok I'm gonna read up on flushing. Now if I flush my plant will it still be fed the N?
flushing means to rinse the shit out of the rootzone man and what you need to do is to take a 5 gallon bucket full of water and test the ph and if it's not in the proper range then you need to adjust it, ...the range you should be shooting for with soil is 6.0 - 6.5.
...and if you don't have a digital ph meter, and you certainly don't need one, then you need to invest in a drip tester kit that will run you $10.00 - $15.00, this you DO need and it'll be accurate enough to serve your purpose. (you NEED one or the other, i'm a fan of low-tech, inexpensive and simple to use so the drip tester kit has been good enough for me for some years now, in fact, i'm still using the same kit i bought i can't remember when, lol)
...once you ph balance that 5 gallons what you want to do is to take your plant into the bathroom and put it into the tub and begin running that ph'd water slowly through your plant, ...go slow and pay attention so you notice when the water starts to run out the bottom and after you see maybe 20% runoff, meaning 20% of the water you've poured in has now leaked out, once you see that take a sample of that runoff and stop flushing while you do another ph test on that runoff, ...now this is important to understand, IF your ph reading from that runoff is higher than the ph of the ph balanced water that you poured in then you have salt buildup and will need to continue pouring ph'd water through your plants rootzone UNTIL the ph of your runoff is at least close to the ph of what you pour through.
...as a new grower i would strongly suggest that you consider coco hempy-buckets for your next run, it is way more forgiving of mistakes AND it is very simple to operate and maintain while giving remarkable and reliable results, i wish i'd found hempy style growing when i first started out i can tell you that for sure!

btw, here's a couple pics of my old cab and my old SuperSun II, ...i still have both but i'm not using either, lol. (i was growing budsickles then)
