there are some problems on the leaves for one week. they become partly yellowish and have brown color on some of them.
do u have an idea? is it an illnes?
or is it maybe that the soil is not enough. I was up to put into bigger pot those days.
I moved to a flat where she gets less sunlight then before
thanks for help
By the looks of it, seems like you have a potassium problem. Next time you fertilize, try using something with a higher 3rd number, like 10-10-30. The 3 numbers stand for N-P-K, Nitrogen-Phosphorus-Potassium. According to my guide book (Agriculture Text book), yellowing and browning of leaves with enlarged veins are signs of (K+) deficiency.

this problem just started for 1 week. do u think it would work to put some K+ now into the soil.
thanks for your interest
i had that problem and i needed nitrogen
I'm WAY too stupid to help you but page 125 of Indoor Marijuana Horticulture by Jorge Cervantes :p(GET THIS BOOK!!!!!! ):p has a picture of the same problem and states that it is a potassium (K) deficiency.Basicly he says to fertilize w/ a complete N-P-K and add a organtic potash and water mixture, with a pre-application PH of 6.5. Foliar feedind in this situation is not recommened. I spent over $100.00 on five different books before a friend let me borrow the only one (M.H.I.) I needed to buy. What the fu............. He has listed his website on the book as www.marijuanagrowing.com . I have yet to look this over (I can't put down the book!!) but if it's anything like the book then it will be time well spent,trust me..... Also, I was wondering if your containers have any drainage and/or holes? It seems like your leaves are curling (down) in a way that they do when they are over watered..........do you have a mixed soil or any additives to inprove drainage? Maybe you should....... Roots love the big O (as in Oxygen)-That's NOT from the book but it's never really bad advice, you know...... :rolleyes:
They look like they're burning. I think you over fertilized.
I actually didnt use any fertilizer, after this situation I bought some with N P and K and a bigger pot. when I took her out of the I noticed that pot was too small for the roots. lets see whats gonna happen.
thank u all for ur advice.
1. I put her in a bigger pot.
2.put N P K containing granule fertilizer into the soil.
3.some liquid K fertiliser to use once a week.
4. my new flat had short light time in the balcony. I use now 6 hours sunlight (I live in Turkey), 8 hours Paulmann plant reflector lamp R80 75W. (how about white flouressent light. is it ok aswell)
5. pruned all the leaves in bad conditions an the big leaves whitout flowers.
she looks better and the flowers made big progress in two days.
