is this N deficency?

[indicando 2]

Mostly on bigger fan leaves, are curly upwards and they feel dry..

I feed them last night with 5.9ph and NPK canna 13-14

If you splash a bit of undiluted fert it can also do this. So can auxins and cytokinens.

Wow thats a mighty tome drunk, Very handy to have.

I have bookmared it for future refference.

Which picture/section, do you think most accurately shows/describes inicando's ailment?

Great work

Peace to the highest.

Hehe great spotting kd, you have the eyes of an eagle, i was too busy looking at fan leaves rofl.

That is a pretty comprehensive post drunk! Thanks for the mission of collating all that info!

I printed it and will read all 56 pages in bed then file it away for future reference!

I reckon Inicando got a pretty good answer on that one!

PS. Would everyone please count three picture up, from the bottom of drunk's post and feast your eyes on that fluffy bud! The heat stress one. I said DAMN!

I really don't know

because I don't splash water on the leaves and not over watered them..

last watering was with sun on the plants..but both plants have the same burnt spots

from middle to bottom, top is fine...so I don't really worry...

beside this the buds are forming nicely..

Just would be nice to know..

[flowers to the people 147]

The problem has been caused from too much water.

The root s need air to absorb the minerals from the medium, if they are too wet then the plant can display all sorts of mineral deficiencies, as the roots are not able to stay healthy and absorb the minerals.

Flush and let the plant dry right out.

then water less often.

take care

The comment of its hard to burn a plant with organic nutrients is entirely untrue. Bat guano for instance can burn a plant quite easily. For all the people who grow with purely organic remember organic soil with organic additives cant be truely flushed. When the last 14 days of flowering comes use massive quantities of water everyday to flush it or else the plant will just pull nutrients out of the organic soil. Be very careful to use bat guano in the right doses because it will be very difficult to flush if you add more than needed. One way to flush organic soil pretty well is using a half tablespoon of epsom salts per gallon of water then pour 1 gallon of water with epsom salt per gallon of soil then after the epsom water is gone through pour pure water (preferably reverse osmosis water with no cal-mag added) through the soil at 2 gallons per gallon of soil and that should strip the soil of most of the built up salts and nutrients. Hope that helps everybody.

Hi all,

I must admit when i first read indicando's problem , i missed that the ph was 5.9 which is a bit on the acid side of things.

When growing in soil ph should be around 6.5 - 7.0 .

I am thinking lock out could be partly to blame .

I have to agree john,it does look like the symptoms of over watering, though soil in the picture

looks dry.

A soil Ph test kit would be handy, available on line and are very cheap to buy , it's always good to have a few of these to hand.

You never know when you might need to measure Ph of your soil and sending off for one when you notice your plant is sick, could be just too late.

Having a few soil Ph kits , is good because you can do an intial test and establish the Ph.

If your soil does need a flush, then you will want to also check after the flush , the Ph of the soil.

A Ph pen will also measure the ph of the water and a TDS pen will measure Total Disolved Salts of the water.

N.W. I have looked through this thread and can't find the comment about "organic burn" that you dimissed.

Though i agree that concentrated organic fertilizer is able to burn if not diluted to the correct ratio.

After all it is just chemicals , they have just been created organically and are essentially contain the same ellements as inorganic fertilizer (N P K & trace ellements).

It is likekly though that inorganic fertilizers are more highly concentrated due to the manufactoring process using pure chemical salts and so they can chose how concentrated thier product is.

N.W good advice about flushing and about using Reverse osmosis water, i totally agree.

I have included a chart which shows how nutrient can be locked out by incorrect Ph.

Diagnosis of Defficiencies ,disaeses and pests, can be difficult at the best of times.

Some interesting point have been made and good observations too.

Lets hope your girl recovers soon Indicano and the buds be frosty.

Keep up the good work yawl

Well picked up Romeu, it was a mistake, early morning fog to blame.

note to self drink coffee first, post second lol.

I need to go take a shower and wash some of that egg off my face

oh the shame.

[Romeu9 491]

It isnt true that the ph values for soil should be 6.5 - 7ph.

7 is the absolut maximum for soil,

but

in veg, values are 5.8 to 6ph and in flower 6.2 to 6.5ph....

Take care
