whats happening to my baby?

Hi rollitup, my first post here but the forum seems realy nice so i expect some nice answers

This is day 21 of my first grow-op, everything went fine (i think) untill about two days ago when one of my beautys started to look unhappy, specially the lower leaves started to hang a bit. Here are two pictures from yesterday:


At this point i thought i just watered it too much so i didnt give it any water yesterday. Although today it looked even worse and one of the leaves at node one is actually falling apart.. theses pictures are from today:


Worth mentioning is that i haven't been giving this plant any extra nutrients.. This was some kind of experiment on how much nutrients acctually helped so i went with no nutrients on one of the plants and 21-3-15 on the other. It seemed to work fine without nutrients up till this problem and the one without nutrients have actually grown faster then the other one.

Anyway, since not watering the plant yesterday didn't seem to help very much i decided to water abit more today, and with nutrients aswell. Even though the plant looks like crap today it has grown about three centimeters, or an inch since yesterday and in my opinion all the upperleaves seems fine.

If you wonder about the setup i use a single 150w HPS lamp that is positioned 50cm (20 inches ) above the tops, the humidity in the closet varies between 30-40% and the temperature with the light on is about 29 celcius, 84 fahrenheit. Ohh, and the strain is super skunk from nirvana and the soil is just some ordinary plantsoil from the local plant shop.

So now to the question, what should i do from now on? Is my little love doomed to die or can i save her in some way?

I have spoken to some guys in a chat, i couldnt show them the pics but they told me to cut off the lower leaves and to give the plant just plain water for some days. I will have to wait until tomorrow with this so i can get a good clean knife but do you guys think this is the right thing to do?

at the pic with the close up of the leave with the dark patern on it , is that patern thinner than the rest of leave ? seems dry to the touch ? is it visible on both side ?

can u make a pic with plain household light ?

NO! You dont want to waste a perfectly good leaf Yet, especially at this stage. A good way to tell if your plant is getting enough or too much water is to put a plate underneath your pot and and wait until the pool of water that was on the plate evaporates or is close to it before you water it again. Your leaf has enough structure to where it will capture light and feed your plant with it. It looks like it won't last but I would wait until it yellows more or turns completely brown because the stem is connected to the stock of your plant and if you rupture it at the connection point while its still green, your plant could get an infection or worse, go into shock. once your plant determines its not going to save the leaf it starts scabbing over the connection point before the leaf falls off. So pluck it then so you dont hurt it and lose all the valuable photosynthesis that those leaves are gonna capture. It wont take long, Just wait another 3 or 4 days and they will be pluck-able. Also if your going to use one light for the full life Id go with Metal Halide Because its not only optimized for veg. It creates a strong plant with a performing root structure that helps feed it when it is in bloom. Also dont do it with a scissors it's not a clone, Use your fingers when its ready.

Yeah the pattern is thinner then the rest, you can see from the top aswell but from that angle the pattern is lighter then the rest of the leave. The leaves seems pretty dry, one of them is actually kind of falling apart when you touch it, you might be able to see that on the last photo.

Here are some more pictures with normal lighting, the pattern is also more visible on these pics (starting to get a hang of my camera ):


Thanks for the help so far!

Ok thanks for the tips. When i watered it earlier today i watered untill it came out on the bottom, but ill definently get some kind of plate for it. When i water later, should i always water it up so that there is water on the plate and always wait for the water to dissapear?

Ohh and btw, i just realized that its only the leaves fronting the door of the closet that are effected. They are also facing away from the light since the light is between the two plants. Could this have something to do with the problem?

Thanks in advance!

im not familiar with english plant health issues , it happens due to low air cyrculation , leave the closet a bit open for a couple of days if u can and if gets better then sure it is , is the "necrosis" expanding fast ?

It all happened the last 2-3 days so pretty fast i guess. I should probably mount a fan to get some more aircirculation then

Yes thats the indication. My plate is ceramic and has a 1/4" lip on it. I fill my plant until it starts to brim to the top of the lip. I wait until theres only a little pool or none at all before i feed it again. sometimes 2-3 days go by. hope that helps

u need air excaust , not just circulation around the closet , when plants will get bigger , if thats the thing will only get worse

I do have an air exhaust, the closet is pluged in to the thing in the kitchen that sucks out air above the oven, dont know the english word for it but its got a pretty good sucktion Earlier i had just a pipe sucking out the air but a couple of days ago i got a carbon filter since the plants are starting to smell a bit and i dont want the smell to get where ever my air is going ^^

Here's some new pictures from two days later:



Ive checked around a bit on the internet and my guess now is that it might be a problem with the ph-value. Could that be possible? Its weird though thats its just on the lower leaves and only on one of the plants..

By the way, im thinking of going into bloom very soon. Is this a good thing to do even though the plant aint perfectly healthy right now?

it seems its spreading , just delay the flower untill u sure on what it is , i havent encountered something like that , if it was only the thining of the leaf it would be a fungus or something in general lurking around ur plant

make a flush and w8 a bit is my call but i havent encountered similiar situation sodont take it as axpert opinion , a flush tho never hurted in veg ( its the aspirine of the growers )

Ok im back with a horrible update

The last problem pretty much solved itself, the leaves didnt get any worse and after a couple of weeks they fell off. I did however get a ph-meter and since the value was a little high i also got a ph reducer.

Anyway, the plats have been flowering for 4 weeks now, one of them is doing fine but the bigger one is starting to look pretty bad. The whole top of the plant is hangning and the edges of the leaves on the top are turning yellow (last time it was only the bottomleaves that were effected).

Here are some pictures of the plant, the first four are of the problem plant and the last one is of the other:



I have no idea what to do, the temperature at the top is about 27.5 so it would be weird if it was overheating.. First i thought i over watered it so i waited for some days too water it again but that only turned it worse, the when i watered it again yesterday it became even worse then that Anyone got a suggestion?
