problem with plants

[s1ncer]

Hello, as i got my grow going on i got into a problem with my plants.
They are 5 weeks into flowering and one of em has brown leafes
like dying of (tip of the leafs) and they are a little curled .
i use cfls to grow and got 150W of cfl in the room
(2 45w ones and 2 30w ones, also i got a little bit of heat issue its sometimes like 32 degrees celsius in there but they have fan blowing nicely on the plants so they get cold air on them.
also got exchaust fan and one for the cfls to cool these down too.
il upload some pics tomorrow ! (also please excuse my english its not very good )

Could one of the leaves have flapped onto one of the lights or gotten too close? I'm not experienced in growing so I couldn't tell you if it was a nutrient deficiency.

I've read that people simply cut off the part of the leaf that is brown to keep it from draining energy and the plant will keep going just fine.

That's only if it's a burn and not a nutrient deficiency. A good sign that's it's a burn is if it's the only leaf doing that.

From what you said it could be a range of things but the first two that come to mind are nute burn or simply the leaf tip was touching the lamp and got burnt. Also if its just the tip leave it be but if the whole leaf is dead than you can remove it.

Also pics would def help & also what nutes are you using if any & how much?

sounds like to much in the nutrient department.

i removed the leafs that had burned . seems to be fine now and then i flushed the soil and after that i transplanted them to bigger pots
i hope its fine now..

humm, a good point for beginners.

a plant having a few leaves with tiny issues, is not a big deal, starting some heavy tour of duty to try and fix things, can often make things worse.

its like your teenage kids having a few pimples and you sending them into plastic surgery.

that being said, i think your plants should be fine.

Hi again i made some pictures so here they are. :

they are about 4-5 week into flowering and its unknown bagseed.

also there arent any spider mites or something like that under the leaves no bugs in the growhouse. so i personally think its nutrient problem but i wanted to ask from the smarter guys.

Usually those littles scars on the leaves indicate some kind of pest. You say there are no pests, and you are probably right, but just for safety sake check again really well. Under the leaf if they are mites they will be pin head sized and extremely hard to see. I usually pick the leaf that has scars off the plant and look for little brown specks on its underside. Usually they turn out to be dirt, but touch them with another leaf tip - if they move get on her ASAP. Also, check the soil very well and when watering look close to see if anything is jumping.

Sorry - I know you seem quite certain that there are no critters, but the reason I am pressing the issue is that I have been fooled before in the past and those marks are a little strange.

To correct your problem of the brown leaves I think you already took care of that on your own by repotting into larger pots and giving water. After a couple days of flush just give the plant half the nitrogen you have been giving her and see how she reacts. If you get no yellow leaves starting to form on the bottom then you were probably over feeding. If you do get yellowing leaves, increase dose to a third. I find making changes slowly is the best bet if things are not too bad,. Other than the damaged leaves the plant looks great -I hope I have been some help to you and good luck!

i looked under all leaves and couldnt find a single bug or thing moving there and i really looked closely...
i havent tryed the soil watering and then looking for bugs yet il do it in a day or so.
also the signs appear on the lower leaves of the plant.
(these are the clones i took from the mother)
and after i started to give them only tap water these brown leaves are disappearing and nice green leaves are appearing now, so i definetaly was over feeding.
thanks for the info and my one question would be if 150w of cfl is enough for these plants?
(also sorry for my english it isnt my mother launguage)

i hope its fine now..

You transplanted during flower?

 

[s1ncer]

yes i did at the time i transplanted them they were 3-4 weeks into flower

Definitely looks like some burn. Try to use a little less nutrients the next time you grow since it's clear that you've been using a little too much.

It happens. GOod luck!
