I have made the mistake of adding nutes every watering, watching my plants explode with vigour and then BOOM...on day you start to see intervein yellowing or burn signs. You start to wonder if its MG deficiency or nute burn or lock or a whole lot of other possibilities. This situationis not worth the extra 10% increase in speed of growth. Go with 1/2 strenght nutes especially in Veg. and alternate with with 1/4 strenght. Water only when the containers feel light in weight. (ie water is mostly gone) Water thouroughly, preferably oxygenated (sprayed) until run off come out of the bottoms. Use a micronutrient fertiliser once in a while instead of your regular nutes.
Before bloom FLUSH. In Bloom phase I go 1/2-3/4 strength depending on what other additives (enhancers) are in the mix. I used flavic acid, humic acid, molases or FLora Nectar, Kelp (Nitrozyme), Vertical growth limiter (Bush master) and a bit of Chaching.
All in all going easy on nutes is highly recommended as difficult situations can develop if you over fertilise.
The above is my opinion only. I know experienced growers that say I overdo nutes and I think they are right.
Good luck
