What type of deficiency is this

What type of deficiency is this only one showing this some just yellowing which I believe i over fed with gaia green

What week are you in?

What week are you in

What week are you in?

Week 5

 

[kramsey1127]

What week are you in?

Its from 42 fast buds says 6 to 7 week flower

Looks like potassium deficiency to me. How do you feed it? Also, what pH levels are the soil and the water you use?

 

[pnwbluntman]

I wouldn't be so worried, the plant is in the bulking phase, it's no longer providing nutrients for the fan leaves, more or so it's plumping the flower, maybe do a flush to help lower the ppm levels a bit in case of a salt build up

Im not sure of ph of the soil but I ph the water between 6.0 6 3 in a soil coco mix from happy frog 2.5 weeks ago i fed 3tbs of gaia green bloom

It does look like you have a slight nute burn going on as well, I would be leaning towards a salt build up. I have no experience with the gaia green so I couldn't tell you much on that aspect, it doesn't look like light burn to me. But in the last two weeks that's also when the leaves start to turn purple

 

[pnwbluntman]

Fox farm products are known for excessive salt build up, I would check the ppm from your run of and check the EC. The soil pH is ok

 

[Phyto]

I don't think it's a deficiency (unless it's a lockout). The shiny leaves are a sign of a bit too much fertilizer. Just give it plain water for a while, and skip the nutes for a couple weeks.

Yeah I figured i have some nitrogen burn can I just flush with water to get rid of the salt build up

I fed with gaia green its gonna just keep feeding

Yes you can. There are flushing solutions to for soil medium plants. But good ol trusty water will do the trick, just make sure to dry back after flushing

You could do a mild flush. but I don't think it's that bad.

 

[kramsey1127]

This is my 1st big run 7 plants 3 Tropicana cookies and purple lemonade from 42 fastbuds and 1 humbolt hero from a local breeder mr mystic happy overall till I week 3 flower and started having the nitrogen toxicity. I fed 3tbs of 444 and 3tbs of bloom to start flower then about 3.5 weeks fed 2tbs of 444 and 3tbs of bloom anticipating I wouldn't feed any more of 444 but feed with bloom once more before harvest

 

[pnwbluntman]

Looks good for your first big set. And phyto is correct, it doesn't look that bad by any means. Like I said it's normal to see this in the last phase of flower. A mild flush will help you from stressing to much. I wouldnt do a heavy flush, just enough to clean it up a bit and dilute down the nutes a little

I run 2 700 watt flora flex right now I have them maxed out should.i run it maxed out all the way through or no I need to back it off at some point I've got some mixed answers from my research

It all depends on the ppfd at the canopy. And what phase the plant is in. Usually the ppfd should increase throughout the flower process by 25% intervals if you are keep the light a specific height from the plant. But there is a range to follow on the phases for flower as well as factors as rh and running CO2 to utilize all of the light

 

[pnwbluntman]

You can run a higher ppfd using CO2 and controlling temp.

 

[pnwbluntman]

Early Flowering (Weeks 1-3): A range of 700-800 µmol/m²/s is ideal as plants transition from vegetative growth and begin to form buds.
Full Flowering (Weeks 4-end): The light intensity can be increased to 800-1000 µmol/m²/s to support robust flower development and maximize yield.
With CO₂ Supplementation: Experienced growers using supplemental CO₂ can push PPFD levels higher, often up to 1200-1500 µmol/m²/s, because the plant's photosynthetic efficiency is enhanced. Without added CO₂, PPFD levels above 1000 µmol/m²/s can cause light stress and potentially damage the plants.
