sick haze

[pseudostelariae]

whats up everyone? i hope you're all well. i have no idea whats going on in my grow room...this morning i opened the door to the smell of vinegar? anyway i've got two arjan's haze3 and while one is perfectly healthy, the bottom set of leaves on the other is beginning to look like this

and the next set is starting up, beginning to look like this

anyone recognize this? it doesn't look like when i've nute burned in the past, and i can't find any bugs on my plants..anybody wanna toss in their 2cents? all i can come up with is a flush(holding off)

Are you saying you fed once in 10 weeks? and it was some guano? high P guano? or N?

 

[DontBanMe]

thats a PH issue...no question...flush good as hell and restore your ppms back to 700 with the right mix.
Youll be back in business in no time.
And oh ya, make sure your ph is in the right range.
good luck to ya man
I see your still waiting on ur pen, well goto the Hydro store and pick up Genral Hydroponics liquid PH test kit for $6 and make sure it is a yellowish orangish color more leaning towards yellow, that has always brought me gold in Hydro and Soil.

Are you saying you fed once in 10 weeks? and it was some guano? high P guano? or N?

yes, i fed with a fairly diluted(about half recommended) guano with a NPK of 10-10-2...i fed at the flip of 12/12 thinking it could use a little nitrogen as well as phosphorous since i've always read that sativas continue to veg for awhile before flowering kicks in. and like you said, it had been 8 weeks with no food, i figured my girls were getting hungry lol.

thanks for the response looks like i'm headed to the hydro store ha

Eh, not a ph issue bt more of a severe underfed issue; I am going to have to agree with petey on this one, you have to feed your plants man; there soil can't make them survive with the stuff in the soil; you gotta feed them. Clearly the soil is overdue and your plants need fed... feed weekly;Looks like nitrogen and calcium deficiency...... and the brown that looks like pH is phosphorus, he is lacking nearly all NPK....


I hope to hell you did not flush, cause if you did and you flushed properly.. you just flushed whatever was in the soil left down the drain........

 

[Core]

i think its a combined thing here....ph probs and underfeeding....

got a pic of the whole plant plz?

 

[pseudostelariae]

good thing i held off on the flush! i was actually worried that my light feeding a short while back could be the cause of this..could have have just awoken their appetites? they could use some water today so what would you recommend? this is the start of their third week flower, at my disposal are guanos with npk of 0.5-12-0.2, as well as 10-10-2..also seaweed extract with 0.1%N and 1%potash
as requested here are full body shots lol

 

[MynameStitch]

You are going to have to mix those guanos and let them sit out 24 hours before watering with them,mix them well and let them sit overnight. i would start out with use 1 tsp per gallon of each guano and for the bigger ones if they need fed use the same unless they are showing severe issues and need fed, then up the dose just a bit.

 

[Kr@kEn]

I'd foliar feed them with something with micros. If you do, use a low strength PH balanced solution (under 400ppm). Foliar feeding should always be done during the first few hours of the light cycle. And the light should be turned off and left off until the plants are dry. Then power the light back on for the rest of the light cycle.

 

[DontBanMe]

I truly believe in what Mandala Mike said if your plants are getting burnt from water being on the plant your light is to close as it is and your plant is already getting fried with or w/o water on the plant.

 

[MynameStitch]

I would love to know how the hell his plants are getting burned when he fed them once with very weak ferts 10 weeks ago; his is very hungry so.... mike is wrong about that one.

They have also been in the mixture for 10 weeks which means most of the nutrients in that pot are used up so again how is that nutrient burn?

 

[DontBanMe]

im talking about burns from water droplets on the plants.....boy OH boy!
i dont remember anyone saying anything about NUTE. burn...

 

[RevolutionX]

trace elements or micro nutes she is hungry for. immobile nute defi starts at bottom, mobile nute defi will affect the newest growth. any wrinkled or twisted leaves i wonder?

 

[pseudostelariae]

i just checked the ph with a simple soil test kit. i would guess its about 6.7...sounds sort of high? franco is saying 5.9 is where i should be about now, so i suppose i need to make the soil more acidic? what would you guys recommend? it would be nice to be able to use some vinegar or something easy to obtain.

 

[MynameStitch]

Please don't tell me that your pH tester was a soil probe that you stick in the soil to test the ph?


This is so simple issue you have, your plants are hungry; organics are slower acting and if your plants are in that soil mixture for a long time the nutrients would be used up... 10 weeks... long time. Mostly high nutrient mixtures say not to feed before 25 to 30 days and even then sometimes that is totaly pushing it.

SO I can tell you right now your plants are starving dude; seriously; it's so simple;

if your ph is being read from test strips and is correct; your not having pH issues. I see more problems from the plant being hungry than pH.

Your mixture is considered soil which means your pH range needs to be 6.5 to 7.0 and you are right in the perfect range which means all available nutrients are able to be uptaked to the plant as long as the soil is not soggy or over watered; so this tells me right away the plants are hungry; given that you said you only fed them once like 10 weeks ago and was a very weak dose of food tells me another piece of the puzzle.... feed your plants they are very hungry and lacking NP and micronutrients.....

Depeneding on what you buy, make sure you do not listen to the back of the bottle for feeding instructions, otherise you will end up burning them and then you will have to flush out the pots to remove the excess you added.

The only brands you can listen to the directions is canna, advanced nutrients and one or 2 other brands.....

So pick a nutrient and post here so we can help you on the feedings; your plants are not that big so you will not need to use very much at all, but you will need to feed them every 5 to 7 days...... until 1 to 2 weeks before harvest.

 

[pseudostelariae]

When was your last feeding and how often are you feeding? i'd say a week ago..just the once

the ph kit was was one of the little test tube chemical/dirt reactions, so who knows how much more accurate than a cheap probe..

 

[MynameStitch]

Ya, those work fine, those are beter than the probe trust me, those damn soil probes always tell you your ph is 7 or a little under LOL.


hell I put OJ in the soil and let it run off and tested te soil and it told me the ph did not change LOL.

Of course this was tested on a small pot with no plant in it

So ya, your ph is fine just get some food into them gals
