Can i add this to my flowers?

So my buds started flowering 3 weeks ago, and looks like nitrogen def. is happening. They are losing their color, i was told i need a blooming base, I have AN Sensi Grow Part a & B, Can I use Part B which is 2-2-5 The part a is 3-0-0 All nitrogen...what shoiuld I do? I also run Big bud n carboload right now

Add nitrogen. If your plants are fading during this period of flower the most common cause is lack of N. Your plants need N throughout their cycle to grow and aid in the transporting of other nutes throughout the plant. Personally I grow according to leaf color and when they start to fade a bit add a little N, wait a week and see what the response was. I will feed a plant if it needs or wants it up until harvest day.
Many people claim, IMHO falsely, that this leads to harsher smoke but the key is a slow dry and cure, which will leave you with smooth taste no matter how you grow.
Good Luck

How did you determine that it's a nitrogen deficiency? If there starting to get lighter in the center of the flowers but the outer edge of the leafs are still green you may be over feeding them. I would get a ppm meter available from any hydro store for around 25-30 dollars. I never follow instructions on bottle, if you are you may be over feeding them. The PPM meter is a sure way to know how much your feeding them, then go from there.

im doing soil grow, im only feeding once a week at half strength, i dont think its overfed, One plant is almost all yellow except buds, its weird. I talked to guy down at hydro store, said it might be nitrogen def. since all im using is big bud, thats only an additive, not base. So when i stopped using my base for veg. all this started to happen, took about a week and half

Now i added last night a boost of nitrogen half strength sensi grow part a 3-0-0 yesterday
The SENSI GROW Part B is 2-2-5, Can i use that as Flowering Base for now?

If this continues you should try using Sunleaves Seabird guano next grow. It covers all the needs of a plant. Almost nuts for dummies. About 12 bucks and will not over nut the plants. Just a good pinch every 3 to 4 weeks from seed to cut. Less is more. I suggest it until you have a grow or 2 of success, then try the others... Next issue is to look at the water pattern as it increases thru flower. Most still over water.

Can I just use my Veg nutes SENSI GROW Part B it has 2-2-5 for base flower nute?

Yes, you can use it.

Also, have any pics of the ladies?

Very nice!

Nitrogen is good i dont know why people always tell you to not use it during flowering. if you mix them you would be adding a 5-2-5 nute. if you use Sensi grow you would have a 2-2-5. I would go with the 2-2-5 over the 5-2-5.

On another note does AN have a product to PK spike your plants with? If you plan on PK spiking your plants you will want to get it done soon.
