ok i think this is from under feeding the jack is a hog last time and this is a jack female with a cindy hermie mostly like jack with the height of cindy

the browning is from the fan blowing on it real hard andthe leaves got really dryed out

 

[HeadyPete]

magnesium def and some phosphorus def (brown patches - not from circ fan)

How do you check your soil ph? PBP is real acidic, so I'd be surprised if your soil ph was as high as you say it is. Especially because you are using CalMag.

How much have you been feeding them?

 

[Dr. G]

almost full strength and i use a kelway soil ph meter and i adjust my nute solution to 6.4

 

[MynameStitch]

agreed; magnesium issue; and those soil ph meters SUCK; get some ph test strips and test the water run off from the bottom of the plant.

Those soil ph meters are expensive hole poppers to plant seeds with if you ask me

AS for the phosphorus issue I don't think that is it; I would say heat is more the culprit than anything else; he is getting radiant heat that is causing his leaves to crisp.

Magniseum can cause leaves to curl upwards but in this issue he is having heat issues along with magniseum

1200 watts at 1.5 feet is close as hell move the lights up a bit. All strains react to heat at different levels; if you grew before and are growing a new strain; that does not mean this strain can take same growing conditions as previous grow strains.

 

[HeadyPete]

Why then is the "heat damage" at the bottom of the plants, not at the tips closest to the light?

I'm still saying phosphorus, respectfully.

I'll bet your ph is way down. Those meters are inaccurate by a wide margin.

 

[MynameStitch]

That crispyness was caused by after bleeching has occured I have seen enough phosphprus issues to know which is which.... not to mention is if was phorpours it would be a different color brown not one that looks like this.

The brown is on different parts of the plant and on different areas of the plants I am looking more over on the other pics.......

Have you grown with 1200 watts before? having them at 1.5 feet is nuts; I have grown with that wattage before and know personally what it can do and when mine bleeched and I fixed the issue the browness that was left over was the exact same look and texture as his plants.

Phosphorus is a much darker brown color not a light tan brown.

As for the ph I bet his ph is off but it's not causing all his problems; which is why I told him to get rid of his crapy tester

Also the leaves he is holding up in different pics have some bleeching on them, bleeching wil show a puke yellow light yellow color where magniseum will show a brighter yellow and tends to slightly darken when it has been there for some time......

On the 2nd pic where he is holding the leave look near his thumb area and you will see what I am talking about when it comes to colors of issues....

there is some whitish bleeching and then there is some yellowing from the magniseum

 

[HeadyPete]

I understand, but why wouldn't the parts closest to the lights fry first? Is that not logical?

Edit - I see the bleaching section in your guide and defer to you on sick plant knowledge. Hell, your guide taught me most of what I know!

Thanks.

 

[MynameStitch]

look in the first picture.... he imay have some reflective material cause he would have reflective material in his grow room which can cause lower leaves to bleech depending on what kind of material he is using

also if he has this plant propped up on something that could cause it to bleech from the bottom too.

I know factfully that is bleeching after the tissue has died from the bleeching.....

 

[HeadyPete]

See my above post.

Cheers!

 

[Dr. G]

no reflective material its in a 4x4 hydrohut yes i have grown with 1200w b4 and its air cooled and the temps in the room are just fine its not directally underthe light at all i dont think itsbleaching its really not that close and ill actually measure instead of guess but my otherroom has 1200w and they are about 16" aways and loving it i stick my hand over the tops to see if its too hot

someone else sent me this

Excessive heat, without a doubt, causes to exhibit chlorosis earlier in the flowering cycle than usual.

The increased transpiration rate (and increased rate of photosynthesis) brought on by the heat causes incrased nutrient uptake causing the nutrient levels in the media to be insufficient thus causing the exhibition of chlorosis...this means that you need to lower your temp, not add nutes. Because your needs less nutes, and is uptaking too much (in my opinion) is why it looks like a combination of nutrient deficiency and toxicity.

 

[MynameStitch]

Some strains are easier to bleech more than others, indicas are very easy to bleech where sativas have more resistant to being bleeched.



I also looked at the other thread you made and they too are showing the same issue you are having here; bleeching always starts in the middle of each leave vein where magnsieum deficiency has green veins.

it's up to you what you want to do we are just here to give advice not force! lol
But whatever you do remember this the damage will not heal so look for other leaves that never had it before to see if you fixed your problem.


Edit: the 2nd pic where you are holding the leaf up; from left to right thr 5th leave look on the bottom right you will see the brown spot but next to it is the bleeching.... now look by your thumb; do you see the spot of the light brown? THat is what is left over after the bleeching has killed the cells of the leaves and that picture prooves what I am talking about and it also prooves it's light bleeching because bleeching is the only thing that causes the leaves to look like that not to mention the color.

 

[Dr. G]

thank you very much i really aprecieate it im gunna feed her one more time prolly then let her go for the flush

ill move my light in a better position
