Mild leaf discoloration

[harris7]

Plant is growing great but its got yellow edges check it out

I think it is mild burn. I flushed it a few days ago

what y'all think?

[harris7]

heres the pics

Overall healthy, possible burn/lockout combination, but mild at the moment. Worth flushing and checking pH of runoff, then watering with mild complete fertilizer at 1/4 strength.

[harris7]

thanks, thats what i was thinking. But i am a new grower so i thought i'd ask

what i did was flush it, and then foliar feeded it a 1/2 strength solution of revive a trace mineral solution which is supposto fix most deficiencies

You might remember from a while back, these plants are in composted chicken manure so it has probably caused a lockout.

[m.g.]

more likely burn if they're in manure AND being fed ferts...

[stinkyattic]

Oh, right! Well, they look good considering.

[harris7]

i'm thinking it is a N deficiency as it also has red veins and stems.

"more likely burn if they're in manure AND being fed ferts..."

I have not really been nute'n it. I have a few times with organics only

Now by 'stems' do you mean the main stem, or the leaf stalks (petioles)?
Because those are symptoms of different problems.

[harris7]

mainly it is the petioles. But the main stem has vertical red lines on it of the same color as the petioles

[harris7]

stinky...

i've fixed the problem. but i've still got red petioles. on a lot of my plants.

and red vertical lines down the main stalks. here's some pics.

it seems that the lines get thicker and thicker untill the entire stem is red

theres a leaf showing signs of nute burn, cut down nutes asap

[harris7]

think so. heres a better pic of the same plant

the plants pH is high around 7 im having a lot of trouble bringing it down

i'll lay off the nutes tho

[emmpey]

think that plant may have thrips judging by the last pic.

[dutch.lover]

so plants that have red petioles- what's that from? could it be OVERnuting with nitrogen?

[stinkyattic]

The way the serrations on the edges of the leaves look pale makes me think micronutrient def/lockout.
HAve you tried bringing your pH down to 6.8 with just a splash of cider vinegar in your nute mix?

[dutch.lover]

we have been pHing out water down to 6.3 but it doesnt seem to be making a difference... i think we have had a pH problem for so long that it's caused salt to build up in the soil (or vice versa)- our one plant had a yellowish colored water running out of it, so I soaked it in water with a pH of 7 for about half an hour. I flushed it with 6.3 water after that and the water running off of it was super yellow, like darker than urine. Obviously the salt build up is worse than it originally looked, so I'm going to soak all of our plants later today probably. Hopefully after that problem is fixed, it will be easier to control the pH.

[harris7]

yes the soil mix we used has too much top soil (basic).
since we now have a pH meter i have been pHing our soil to 6.4 and our nutes bufffer to like 5.9 so it should average out pretty good

[Abattoir Dream]

well, I heard composted chicken manure can burn easily, so its probably safe to say you wouldnt be having this problem with normal compost, anyways, good luck

[harris7]

chicken manure is like a personifcation of the devil. It has caused almost every problem we have had.
1- it'll burn the shit outa your plants
2- it's ph is bad
3-it's full of Na which bonds to P and other things causing salt lock ups and P def.

you are very safe to say that
