Dynagro bloom = nit def? (soil)

Seems like DG Bloom, Mag Pro and Protekt isn't enough to prevent nitrogen def. Adding 3 ml / gallon of grow seems to fix it - does this sound right?

Sometimes you need to adjust nutrient levels independently for Nitrogen. This is because particular strains have unique nutrient requirements. I keep a jug of organic nitrogen 5-0-0 and boost nitrogen as needed for one feeding schedule (regular feed plus ~5ml of nitrogen) and watch for results ~3 days later. I use hydro but I have grown in soil.

hey tibberous, yes thats right buddy, use grow as base nutrient....it will balance nicely...during veg stage you can use bloom for base nutrient...once you hit the flower phase..use grow as base nutrient but you seems figured it out, good job, sir. +rep for ya

fwiw, I use dynagro bloom in hydro with no N deficiency.

I also have never experienced any N defecits using Dynagro Bloom. Troubleshooting plant symptoms can be tricky, for example the temp plus humidity plays a large role in how the plants uptake nutrients. Lots of time the nutrient gets the blame where the problem is actually elswhere and usually enviroment variables are at fault.

Dynagro is one of the few formula's out there that does not use UREA for a nitrogen source. When using UREA for nitrogen, you need bacteria to break it down first before it is available to the plants for uptake. UREA is ok for soil but you need a good micro-herd for it to become available to the plants. Most DWC and RDWC folks run sterile tanks and use a formula that has UREA in it which can be a problem. The nitrogen is there, just not in a usable form yet.

UREA = Mammal urine.

Peace!

UREA = Mammal urine.

I wonder why mammal piss is so quick to give a nitrogen burn on my lawn?

I have experienced the N deficiency too in flower but think I found out why. We all know plant nutrition is a balancing act and when using only bloom and protekt, that seems to be about as much P as the plants can handle relative to the amount of N which keeps plants green. When using bloom, magpro and protekt, I've found that this seems to supply too much P relative to N (causing a slight yellowing of the lower leaves) at which point I will balance with grow (which adds more N). Another thing to keep in mind is the nutritional requirements of the plant given the stage of growth. I find that the needs of the plant are different during the first 3 weeks vs the last 3.

Okay - not so bad once you realize whats going on.

Big thing I guess is just keeping records so you can adapt.
