some plant trouble ...

[dirtdevil]

i had an earlier post but i have been so busy i figured i would start a new one . heres some pics . i thought i had figured out my problem but i guess i didnt , my water was acidic and she was burning up . i used some lime to correct the PH in the water and have seen it getting worse in the past few days .... heres a few pics , i stoped all nutes for the past 4 days and flushed it well 2 days ago . browning is getting worse . the plant doesnt seem to have many leaves and the ones it does have are browning:(

more details on the ph.... how low was it. what ph are u aiming for?

this is one for sticky i think.

it's look like low Nitrogen to me. I used to have something like this so i put 29-10-10 fertilizer for a couple weeks, and move the light and bend some stems in order to make most of the leaves recieve the most light then it was gone.

I don't have any idea about the pH so im not sure but you may try my solution. i still have a few(just 1 or 2) of leaves like that.:rastasmoke:

If you fill out the troubleshooting form (http://boards.cannabis.com/plant-problems/127058-troubleshooting-form-yay-you-know-you-wanted-one.html) you will get more help and more definitive answers.

It may be a deficiency but it does not look like a Nitrogen deficiency to me. N defs start with yellowing of the lower leaves and works its way up usually with a noted paleness as it does. It doesn't just affect the tips and edges or make them crispy and up-curled quite like that. It is more likely nute burn, which does start at the leaf tips and edges. It is hard to say with such limited information however.

If your plant looks like this and I think it dose, it is definitely an over-fert problem. The high level of nutrients accumulates in the leaves and causes them to dry out and burn up as shown here. You must flush with clear, clean water immediately to allow the roots to recover, and prevent further damage. Now find the cause of the high nutrient levels

yeah right, it should start yellow from the bottom. my bad sorry :D:D

That looks like a nutrient burn - Nitrogen deficiency should start at the lower leaves because the plant is consuming the nutrients from the lower leaves, moving them up to the new growth above. That is why the lower fan leaves yellow and drop as bloom progresses - the plant is consuming itself while it focuses on nurturing its buds and, it hopes and we don't, its seeds. Burning occurs from the top down because transpiration causes water to be lost from the leaves while the salts remain behind - the further from the roots and the closer to the lights the worse it will get.

You need to flush the hell out of that plant.
