Deficiancy or burning?

Can anyone help me with this problem?? I finally got a ph meter and the kit and I'm still running into problems... What is the best ph for soil cuz I thought it was between 6.5 and 7.0? I got my ph at 6.5 and ppm at 425 so I hope it was just burning cuz I flushed to hopefully control the problem temps are also between 86 and 82 but I got some fans with speed controllers comeing soon so hopefully I could start regulating temps...what can you guys say about it? I use dynagro bloom and protekt and if it's a calmag Deficiancy then I need to get calmag plus. The dynagro has calcium and magnesium so I figured I didn't need it...

It looks like root zone trouble to me. I'd repot into good soil. cn

i agree your root zone ph is off.
how are you determining the soil ph?

I would say nute burn caused from your room being 86degrees plants can't handle the higher nute with higher temps. But it does aswel look like some ph issues how long ago did you get your ph corrected and how did you measure it?

Crispy tips...burnt

I would bet your humidity is too low as well At those temps you want at least 70% humidity Your plants are transporting like mad and taking up water to keep the leaves cool. They are absorbing a shot ton of nutrient salts with that water. Hence the burn and deficiencies

Thanks guys I didnt know you had to check the root zone ph till researching last night...how do you guys check em. from what I read it says adjust ph in water then test runoff in catch tray so I'm gonna try it tonigh but already did one flush. I only got the meter a couple weeks ago and when I first adjusted the ph the plant looked great! It started this prob mid last week and I didn't know what happened so hopefully I could get the plant back on track...thanks for the help guys!! I'll update if things get better or worse!

When I run into a mess. I always start with the soil Ph. first
Make sure I'm in 6.5-7.0
When the root zone Ph is off... You will get all kinds of problems that look like nute def, burn etc. Caused by low or high Ph...normally high ,lock out.
So, what do people do with out knowing the soil Ph...that's right, give more Nutes etc.
That's right, does no good only build up.
Some people get confused with Ph water and Soil Ph.
In your case, I would flush with Ph water and get her in balance and excess salts out..
After flush, Ph corrected, add very light nutes to start.. should see results in 5-7 days.

Good Luck

Some reading for you.

Thanks for the link! Also humidity is at around 55-70 deg.

That's a good humidity Also, you REALLY need to calibrate your meter Especially if you have a cheap one They float all over!

did a heavy flush to hopefully even everything out...runoff shows a lot of salt build up and the ph of the water was adjusted to about 6.4 and runoff was at 7.0 so root zone should be at 6.7...that shouldn't be bad so I hope it was the build up...The ppm of the runoff was at 896 so thats double the ppm before it went in the soil...please tell me it was an over feeding!!i do a lot of research and I get most of my answers but I really need help cuz it shows it could be a number of things but I always get problems solved when I post up o RIU so thanks in advance!

That area between the light and the plant (the canopy) is shit hot, my friend shit hot. You need cooltubes for the next grow ,also it looks moisture stressed as in your letting the pot dry too much in low rh.

No your ph of soil will not be less then your run off.... 6.4 in 7.0 out where did you get 6.7... Maybe 7.4 flush more until the runoff is very close to what your putting in. Why would you think your ph is lower then your runoff, if your soil was 6.7 you ph could not reach 7.0. Good luck man.

Umm,I think you mis read keep it real. Those PPM are not real high.. but combined with the heat and transpiration, they are high.

Sorry guys the root zone ph thing is something I found online they say the root zone ph is in between the ph adjusted water and runoff. I don't know guys just going with as much help as I could get. Anyways im gonna see the progress tonight and I also raised the light to about 10 inches above the canopy...anyways thanks I'll be workin on this problem so if there's anything else you think I should do feel free to add on!

Oh sorry about the ph thing again I made a big mistake I believe it was that the runoff ph is mid of pre water and soil ph so watered with ph of 6.5 runoff was at 7.0 so soil ph should be around 7.5 correct?

Best soil pH is high 6es. I read somewhere that runoff pH is not a reliable indicator of actual soil pH. I don't recall where, alas. cn

That's what I said the plant can't handle the nutes because of the heat and the speed at which the plant is losing water and replacing it, and yes 200ppm is not high but if its burning the plant. It's to (high). I would also like to add man dyna gro is amazing so far, it has all essential minerals. It's crazy contecentrated!! Hope all goes well.

sorry bro but i'm using L.E.D. so it's not getting too hot. can l.e.d. still burn? it's a bloomboss 90watt. any help would be great! thanks!

yeah i know DYNA GRO's one of the top brands i started my first grow with miraclegro and hoped upgrading the nutes would help. i ran into this type of problem in the first grow and i'm kinda disappointed i'm at the same prob...last night i did a heavy flush and let about 3/4 of a gallon run out. and the runoff is still up toward 7.0 and when i inspectect the plant today after work it looks like it spread so i went ahead and took off a couple branches that had no chance...

here's a pic. if someone knows anything else i should do i would appreciate the help!

okae guys upon further research on this VERY HELPFUL thread!

https://www.rollitup.org/general-marijuana-growing/488960-pot-plant-problems-visual-guide.html

it could be one of these things:

1. over fertilization(pics look very close to the changes in the leaves that i noticed)

2. nitrogen deficiency(only because i only noticed after i bought the dyna gro the NPK is at 7-9-5 and from some vids i watched comercial growers use DYNA GRO foliage pro instead of liquid gro...)

3. excess potassium. (i know this is the same as over fertilization but in the thread it says "excess potassium could agrivate the uptake of magnesium, ect...cuz this looks just like a mag deficiency)


what do you guys think? someone please help me decode this issue!! i got the plant flushed and i'm gonna flush a second time probably tomorro...
