Pandemic Problems: Nitrogen Toxicity and Homemade PK booster

fatasstrex · Apr 25, 2020

Hello, my plants have recently been diagnosed with nitrogen toxicity. They are in late bloom. I want to still feed my plants P and K but my bloom nutrients are 2-8-4. Because of coronavirus, I'm unable to get nutrients from amazon or elsewhere for quite a while. Anyone know of a way I can make a homemade PK bloom booster? (Or perhaps isolate the N and take it out of the nutrient solution lol :lol:

)

MKP will give you all the extra P and K you're plants will need for a boost without any N.

That bloom formula should only be used during the stretch in early flower. It has way too much P.
A typlical npk ratio of 2-1-3 would work better, so if you're able to find a dry nute mix with those basic proportion(2-1-3) that also incorporates your micronutrients should work.
Good luck

So would the the 0-52-34 MKP be harmful in late bloom?

You have to be very careful with such potent nutrients, a little goes a long way.
Most bloom boosters contain a combo of MKP and MAP - mono ammonium phosphate 12-61-0.

If you have a favorite bloom booster you can read the ingredients and give it a go.

Personally, I would think your original formula would serve you well through flower.
I don't see why you should be getting nitrogen toxicity from such a low ratio.

MKP should be used during the flowering stretch. The plant really needs the added P only during the initial flower and then returned to approx 50ppm. Running higher concentrations will produce toxicity in the plant.
