My dear sensi*...orange speckles??

[slickrick]

Hi guys, I got some free seeds which i believe to be sensi star and have planted two, one of the plants is extremely healthy, the other, is growing well but has orange speckles on it leaves, mainly lower to mid but it looks like they are moving upwards. Im using 2x20w fluorescent bulbs temp is about 76 degrees f and both plants are kept in exactly the same conditions/soil. See the pics, the orange seems to be mainly on the veins of the leaves, can anyone give me a diagnosis??
nb the last pic is my healthy plant.

Thanks

ooooh, I'm gonna take a stab at it and say that you ph is out of whack. This is causing a nutrient lock-up. Give a good watering with plain ph'd water. Ck the runoff till in the right ph.

If Im using the same soil and conditions how can one plant get a nutriet lock up and not the other? I havent added any extra nutrients to the soil, is flushing/ a good watering still a good idea?

Ph Problems
One of the first signs of having a slight ph problem is, your plant having part of the leaves kind of twisty, spotty with brown, yellowish, red spots within each other.
Sometimes they donâ??t have to have all the colors, they could just be spots that have yellowish brown, or just reddish brown and can happen anywhere on the plant. Mainly starts on big fan leaves then goes to little leaves.
When this happens you need to check your soil ph, water ph before and after adding your nutrients. One of the biggest causes is adding nutrients like earth juice; they take the ph down quite a bit. Also can happen when you add bone and blood meal to your soil, that will throw the ph off as well, so itâ??s smart to test the mix before putting your plants into the mix. After the spots happen you will soon see nutrients being locked out, when that happens DO NOT ADD ANYTHING TO FIX THE PROBLEM UNTILL YOU GET YOUR PH FIXED!!

You don't need to have fed to have ph problems. What is the ph of the water you are using? Take a ph sample of the run-off on that plant and let us know what it is.....:)

PS, go to the aforementioned site and look up the section I quoted and take a gander at the pics......

PSS I think it is starting in the other plant too...I just inspected that last pic...look at the bottom of it.

ok thanks for the input, im waiting on some ph testers to arrive atm, will keep you posted, i noticed a slight browning on the other too, the testers will arrive soon. i was using an old sprite bottle for watering, maybe that has caused a problem.

the probelm is not knowing what your ph is. if your ph is 8 then u might have a problem, and if you dont have a ph kit then u will never know. So one u get it, check you ph asap and adjust it asap, check your run off ph the most, and adjust from there.

Ah, perhaps too it's spraying the plants with the lights on? Not a good thing to do. If you must spray do it just before the lights go out or soon after, never while lights are on.

Also, check you PH...that too is a must that all serious growers do. But usually it's checked at the faucet...

[slickrick]

will do, i havent sprayed them so i can rule that out, all boils down to the ph i guess

[slickrick]

i just checked my ph, and the ph is 7.5

[Bree1978]

Not too bad, but a little high. You want optimally to be around 6.8 in soil. Did you also ck the ph of the water you have been using?

yeah, the water is more or less exactly the same as my soil, would adding a water and lemon juice solution be a good idea to bring the ph a little lower?
one of the leaf branches fell off today and it was all dried up. I was also looking at my soil and thought that the soil may be too compact, maybe the soil needs to drain better?

[Bree1978]

you could use lemon juice, i've used it. I wouldn't use it again...if you can get ahold of ph down do so. If you can't perhaps you can get some reverse osmosis water or distilled water to water them with. They are ph balanced. If you continue to use this kind of water you will need a cal-mag supplement.

[slickrick]

I just repotted them and they have picked up really well! My diagnosis would be the soil being to dense and compact so it held water for a long time. Its a lot better now, 1 month old, should be sexing soon shouldnt it?

[Bree1978]

Are the nodes alternating yet? When they are whip out that magnifying glass...yes I said whip it good....crack that whip...lol :jointsmile:

[slickrick]

What do you mean by alternating nodes? I ve looked up the term but I would be greatful if anyone could post me a picture so i know what to look for.
