New Grower Polo's not so happy plant! Help needed

[Muddy]

Nute burn will show up on the very tips of the leaves, not along the edges like that. That's the beginning of a potassium deficiency. If left unchecked it will continue along the edges until they turn yellow and brown. Most likely causes are a lack of P or a pH imbalance. Did you check your run off the last feeding? If so, what was it reading?[FONT=Arial, Helvetica, sans-serif]Postassium[/FONT]

I'm using color matching to test the ph and it showing 6.5 yellow. Here are some pictures of another one of my plants thats showing the same signs.

Figured I'd start a new thread to get a faster reply. Its been about 7 hours once the feed and I noticed one my TD's is very droopy and has some spots on the leaves.. I used 3ml/L of Iguana Juice and 3.5ml/L of Root Juice. Water was ph'd. I went ahead and did a flush just now just to play it safe. Plant is 30 days old.

Any thoughts guys? My initial thought was nute burn. Other 3 plants are showing no signs of anything; looking very healthy.

Looks under watered to me. Mine looked like that this morning, I had not watered in a couple of days.

Well the droopiness was not there before watering. 1 of the 4 plants took a lot longer to recover from watering; 7-8 hours later it was still droopy.. now they all are up and about. Main concern are the spots on the edges and some closer to the middle. The spots are only in some locations.. generally leaves in the same area are affected; different stems though... to me majority of the leaves affected are middle of the plant not at the lower leaves. and we are talking maybe 10 leaves affected in total.

My bad, well guess something stressed her a little or something. Is your PH in check? Run-off etc? The leaves don't look super bad? Maybe a little too much with feed? Sorry not sure what your using. Are you watering slowly?

Maybe a more accurate way to test PH is needed? Yellow on my old strips was always under 6.0?

It appears you have a slight case of nute burn and I also noticed some of your leaves are clawing which could be the beginnings of a nitrogen toxicity. When my plants are in trouble I always refer to this web page and I actually made a copy of it. http://growweedeasy.com/marijuana-symptoms very helpful information.

In addition, when asking for advice in this forum, I've learned to always give as much information about the grow that you are able to give. Examples, type of lights and wattage, growing media, age of plant, line of nutrients, room temperature, relative humidity etc, the more the better to diagnos.

NOTE: I found that PH strips were extremely inaccurate and the longer they sit on the shelf the worst they get, both strips and liquid.. I purchased a Milwaukee PH meter at Amazon, it also has a temperature probe which I needed for my Bubbleponics system.[h=1][/h]

When I deduced ph fluctuation for my white/cream-colored spots on my leaves, I did so using this resource at grasscity. To me, it looked like something between burn (crispyness) and loss of pigment. Not yellow like tips or edges. More white and often in the main area of the leaf.

If you want to compare that deficiency to others, the parent page at that site shows all of them with photos.

Yours (especially after posting the second batch of photos) looks exactly like what I have gotten at times when going too low in ph, or when bouncing around too much between 5.9 and 6.4. And, now that you said you're using a paper-strip ph test.... I bet you set yours wrong due to how imprecise those testers can be.

you should see the price of the ph meters in my country compared to the states! 3x the price!! that has been my only reservation in regards to purchasing one. Since at the moment I am unemployed and going to school. any suggestions on meters from amazon? I have a bunch of friends in the states so they could send me one.. (used to live in the states for 14 years until i was deported in 2013 for selling 2 oz of pot back in 2006 x.x)

I've used two inexpensive meters from Amazon. I really like this one: BestDealUSA PH-009 for $8.50 US. I have another by Milwaukee which cost about $25. Looks exactly the same. But, I don't like it as much. (It reaches its final reading too slow, its calibration screw is too sensitive.).

I really like the Best Deal. For the price, you could run two and use them to confirm each other. Might reduce how often you have to calibrate. (I do this using the Milwaukee and BestDeal.).

The more expensive investment is the 7.0 calibration, storage and probe cleaning solutions. You won't use much of these things. But, they're essential to the longevity and accuracy of the pen.

I've had my BestDeal pen for 6 months. I put 6-12 drops of storage solution in the cap. Soaked the probe in cleaning solution for 12-24 hours once. Calibrate maybe weekly. It might stray by 0.1 every week.

Yea, its could possibly be some burn. My initial inspection made me think of over watering and to much N. The claw effect is what made me think of N. (correct me someone if Im wrong, Im still learning lol). From what Ive researched. If Im not recalling a different type of deficiency/burn.
