What's (still) wrong with this plant? - Pics attached

[Jimmy Talons]

The small sick plant I posted about a couple weeks ago has gotten a lot bigger but not too much better as the pictures of the leaves I posted were so bad and blurry nobody could really make a diagnosis. So please find attached a few better snaps of this sick plant of mine. Wrinkled/shrivelled leaves is all I can really describe it as. Not too sure why this is happening as it's the only one in a group of 7 with the exact same set up. Soil is good; 7 parts John innes no 2 and 1.5 parts perlite and vermiculite, pH is around 6.7. Nutes are the following:

Any advice or guidance will be much appriciated! Thanks a lot.

Here are the pictures:

Hmm. I have no idea what's wrong with it. You should use the photo upload tool to upload your photos though. Just my thoughts. I wish you the best of luck with the plant. Hopefully someone else can help you more. Keep us posted. Take care and be safe.

Hi. I went ahead and edited your pics as we don't allow Photo Bucket picture service to be used on this site for saftey reasons. If you need help uploading pics another way just give a yell. Looks like you might be having some problems with your nutes or heat. What are your temps at the top of your plants?

Thanks for sorting out the photo's BG, I was trying to use the recommended method but I had to download something for my mac that looked slightly complicated and I thought it would be ok to just use photobucket. I'll get it for next time.

Anyway it's 27C or 81F.

ph problem.. plant in nute lock. plant not getting P and K

what are you using to test your ph??

 

[Jimmy Talons]

it's a little contraption that you stick a rod down into the soil and then a line on it's face moves slowly to whatever it makes your pH to be

Jimmy get rid of that thing, i have the same thing and it just doesnt work when it comes to MJ growing, ive had mine for a year and never used it. you need to get some ot he ph test kits that they sell for aquariums, its inexpensive and works a heck of a lot better than the PH rod. Good Luck..:aok:

:spit:It's amazing what H2O will do... lol... eace:

I'm going to stop adding the nutes to the water for a while (I think the leaves are looking slightly dark so I probably should right?) and i'm picking up a proper pH testing kit today. First time grower so forgive when I ask what action do I take to correct the pH if it is too high or too low? Thanks again for your help.

 

[Jimmy Talons]

the only ph test kit i could get is for testing water, bought it anyway, is this any use? i guess every aquarium ph kit is going to be for water though. how does this get me the ph of my soil?

Hey Jimmy- come get to this...you need to grab a soil ph test kit, hit up a garden store or walmart or outdoor supply store. They should carry either a capsule tester or stick tester. Stick testers have very prudent directions on soil and wettness. Capsules can test all soil samples. A good flush helped my plants from the wrinkling that had occured. It has not resumed yet. IMO, flush it out....ya dig?

 

[Jimmy Talons]

thanks man, i'll get on that tonight.

You kidding me man?? how u think i learned ? i didnt know crap about growing MJ 2 years ago, been here since and been well thought by some really great people.
ASK AWAY my friend, its all about all helping each other... Good Luck.

to test soil ph you just test the runnof water when you water it, but only uyse that method in case you cant find a souil test kit.. Good Luck :aok:

is it an hid that is close to the plant? seems as if this plant might be in a hot spot of the bulb maybe? do you have a photo of your entire setup and where everything is situated while the light is on?

what are the temps like? one plant- is it different genetics? do you have a buffer in the soil?

we need more info.

 

[Jimmy Talons]

Thanks people, here's a picture of it about 2 weeks ago

the plant was situated where the plant on the middle left is

here's a more up to date photo

I moved this plant to the back left corner a few days ago, the temp in there is 26-27C or 80-81F. The plant is the same seed as the rest (that i'm tending to), and finally sorry TOA I don't know what a buffer is?

 

[trillions of atoms]

a buffer is added to the medium to keep the ph in the rootzone stable. how do you check ph near the rootzone?

you need to test the runoff with a digital meter, that has been calibrated. if you dont have any powdered dolomite lime then i would get some.1-2 table spoons per gallon of medium watered in should help. the leaves look like a ph problem, but the way the lower fan leaves are rolling inward from the edges and new growth is curling says intensity issues.

id be willing to bet the ph is off and it needs a dose of some calmag and micronutes.
