N and P deficiency

I have 2 plants that are about 5 weeks into flowering. I recently switched from using miracle grow all purpose once a week to BC grow liquid nutes 2-3 times per week. When using the MG my plants never showed any problems. Is the BC grow complete crap? Do i need to give nutes more often with organic stuff like that. Both plants are showing the same problems.

Technaflora introduces a way to have a superior hydroponic crop in two simple steps. Use B.C Grow (1-3-6), B.C Boost (3-0-2), and B.C Bloom (1-4-7) in the tested and proven mixing ratios printed on every label for optimal growth and maximum yield. Unlike some other three-part nutrients, B.C. Nutrients are easy to mix and control because you use just two parts (Grow and Boost or Bloom and Boost) during any growth stage.
Are you using both parts? How much are you using?

I am using Bloom and Boost plus some stuff called awesome blossoms 2,11,11. I use about a 1/2 tsp of each in 16 oz of water

Ok. Let me see if I understand. You put 1/2 teaspoon of bloom and boost in 16 ounces of water. You also add 1/2 teaspoon of 2-11-11 awsome blossoms.

I can tell you right now, your toxic. :yoinks:

Answer

Answer

Flush the soil with plain water well.

Apply 1/2 teaspoon bloom and boost per quart of water. Don't add awesome blossoms.


Here's the math:

boost and bloom at 1/2 teaspoon 16 ounces:
(ppms)
n 210
p 90
k 389
ca 184
mg 78
fe 5.26
mn 1.04
zn .78
cu .15
b .5
mo .025

Then you added awesome blossoms

n 105
p 249
k 480

Total npk
n 315
p 339
k 869

Your plant will die :yoinks:

Suggested new rate of 1/2 teaspoon per quart withouit awesome blossoms:
n 105
p 45
k 195
ca 92
mg 39
fe 2.63
etc...

Adjust fert water ph after adding everything for best results.

Good luck growing!

He hasn't even told us whats wrong with them and what the symtoms are?

Are they yellowing or burning? Are the falling over or stretching?

Need info before we can suggest a cure don't you think?

It could be something like lock up from changing nutes for all we know?

1 out of 2 got fucked up. wow im a dumass. i flushed them today and can already see a difference.
You gave alot of handy information about your ferts. Without pictures, I was still able to give you a diagnosis. Kinda like flying a plane at night with instruments only. When the instuments say your heading toward the ground, you better pull the nose of the plane up. Wait till you see your cannabis infirmary bill. You should be receiving that in the mail in the next few days. :D

Doesnt take a genius to figure out 2-3 times a week feeding is too much.

Also asking sproutco/blackvelvet to wait until he sees a picture or hear many details before his 'patented' lucas method diagnosis is asking too much.

He would flat out rather be wrong 1,000 times as long as he has one post he can wave around to say he was right.

As long as they know hes never grown a marijuana plant in his life I could care less.

That is not too much. He should be feeding with every watering. He was using too much ferts in the water with n and p over 300 and k at 900. That's bonkers. Sorry you didn't understand how to read the ppm numbers I provided.

Sorry but youre wrong. No one using soil should feed on a daily basis. Thats just going to get him right back where hes at with too many nutes in his medium.

And without a picture to tell you how big his plants are and in what condition your formula isnt going to mean much. Like someone said math doesnt grow plants and its pretty obvious neither do you. If you did you would understand you cant slap a formula on a plant that diverse and think its always going to be the right answer. Especially when you dont have a good picture and as little information.

Verite,
i agree with you daily feeding in soil is overkill. Even every other day is pushing it unless you're plants are in some gigantic pots.
