Nitrogen Mayday!

[dejayou30]

My nitrogen deficient plants are getting worse! I don't know what to do! Pretty much all the large fan leaves of the one plant have been consumed, and now my best looking plant is starting to turn really yellow towards the top. I am on day 23 today. What the F should I do?

What's your nute system?

I'ld need some info on grow to even guess wildly.


medium.
temps
nutes
ect.

very quick fix would be foliar feeding? just a guess....

[dejayou30]

I'm feeding the 50/50 veg/bloom mix right now, have been for 5 days now. I also use Liquid Karma and SuperThrive. My temps are all normal. My PPM was 1950 when I checked it like 10 min ago.

1950?

N~P~K?

ph? you are hydro? near 5.8?

[dejayou30]

I don't know the exact ratio of NPK since I'm doing the 50/50. The Veg is 4-1.5-5 I think and the Bloom is 2.5-2-5. Its Pure Blend Pro. I'm using hydro and my pH is in a normal range, 5.7-6.1.

ppm seems high . what stage of groth are you in .

Day 23 of flower

[420freedme]

6.5-3.5-10

3weeks into bud. imo that too much N and no where near enough P. in bud i use 9-50-10 for example.

ppm seems high to me to, but I'm not current on hydro. coir jor self mix soilless here. all soilless atm.

idk your nutes, but most 3-4 week budding plants need their cal and mag avalible. imho

Have you tried a foliar application of your grow nute @ 25-50% of standard dose?

I'm also wondering about root zone issues- what do your roots look like? What's the res temperature?

Are you still using that Hanna that won't calibrate?
