I use both FNB veg and bloom. I started out with only the bloom, but let me tell you the veg formula rocks, my plants love it, they grow fast!
Wait.... are you topping off your res with water before taking your measurements? That's very important. I top off twice a day when I can as it keeps things on a slow gentle change.I have not add back yet, but will at 1/3 strength.
Since my ppm is rising, that means there drinking abit more then there eating right now. correct? since its not a drastic increase in ppm, it is safe to say the nute solution isn't to strong, no tip burn either.

I use FNB in bubble buckets. I have low ppm tap water, so I don't adjust pH thanks to the pH buffers. I swap out nutes every week and a half or so and have had no problems with strains like Neville's Haze, Skunk 1, Blueberry, and Northern Lights.
For flower, I add a teaspoon of Liquid Kool Bloom when I see flowers forming, then 2 teaspoons at day 21 to pack on the weight. I use dry Kool Bloom the last week and a half at a little less than 1/4 tsp. per gallon before flush.
It works well. Very little trimming. Very hard nugs.
Be careful with FNB at 8 ml/gal. It is better to start off with 6 ml/gal which should put you around an EC of 1.8. Then you can watch your plants and the EC/pH of your res before you top off with water and adjust accordingly.
The 8 ml/gal can cause tip burn, leaf down turn on certain strains. In my opinion it is better to start on the slightly underfed side and adjust up as this will cause less stress on your plants than starting with an overfeed and then trying to remedy that issue.
FNB should be all you need for most strains. However, if you have a nute hog strain and you find yourself needing above an EC of 2.0 you have the option, at that point, of adding a PK boost. The FNB will be providing plenty of N at that point in flower no matter how big a pig your plants are...so if they can take it, no harm done in feeding them more PK with the possible benefit being bigger yield.
Hope that makes sense and helps.
Edit...the Rez Dog formula is specifically for coco in a dtw application, it will, imho, not provide enough P and K for other mediums. You will be much happier with Lucas unless you are using dtw coco. That formula is based on the cation exchange capacity of coco and the perceived tendency of the coco medium to exchange K cations with Ca and Mg cations allowing one to run lower levels of K. In my opinion (and possible only my opinion) this depends on how the coco manufacturer treats their coco...any good one will "clean" the coco to rid it of Na (and again, imo, this will also rid the coco of K). At that point good coco manufacturers will add something to satisfy cocos cation exchange capacity and exactly what they add back will influence what formula is best...to the point the cation exchange capacity has been satisfied. It would seem to make the most sense to use Ca and Mg to fill that CEC although some manufacturers seem to use K to due so...if they use Ca/Mg then it would seem the Mel Frank ratios would be appropriate from the get go, if not then perhaps the H3ad/Rez Dog ratios would be the way to go...although those are still for dtw, if you are recirculating using those ratios at higher concentrations would be appropriate. Even then, once the CEC has been satisfied the Mel Frank ratio should once again, become the way to go...perhaps this is why Rez Dog has success adding some PK boost as he goes.
Then again, I could be wrong.
Enjoying your thread but have to disagree with your take on coco. I think it's just the opposite (imo). I've found coco to be extremely consistent and have never treated my coco(Atami bcuzz). I find that ppl tend to over think coco and treat it like soil in alot of instances and this is where the trouble begins(imo).
Good luck with your grow
They look really healthy. Good job.
Any one still seeing the anonymouse vip logon still come up? its a proxy server. and i made a few changes. i hope it gets fixed.
IT IS NOT SPAM...
Let me know.
Updates later on.. day 14
B-safe
What in the world is this pop up man? Sorry but it needs to go away. The ONLY passwords you enter is for the log in of this site not your vip box ok?
Folks have used proxy servers on here for years and I have never seen anything like that it's not right.
