Wow, again, looks exactly like my problem. PH lockout.

This was mine: http://www.rollitup.org/marijuana-plant-problems/586902-whats-happening-my-plants-pics.html

PH test your tap water and make sure its 6-6.5, if its not you need to adjust it as needed. Test the soil on your plants as well. I think you'll need to do a heavy flush with water PH'd to 6-6.5 asap.

Soil grown marijuana enjoys a pH level anywhere in between 6.5 - 7.0. Your regular water ph level is perfect, however you need to adjust for the nutrients you added, which lowered the pH way down below the comfort level of marijuana. I use lime to correct pH imbalances in nutrient solutions, however you can also use pH up to raise your pH out of the acidic range and back up towards neutral.

Lime juice is not some you would want to use, you probably mean lime, which is just ground up limestone. Lime juice is acidic and would only worsen your problem.

i heard baking soda can help but the the best option ...but if needed maybe i should use it ! what u think!

Baking soda in small doses is effective at raising pH. I highly suggest pH up though because it lasts longer and is more effective, but baking soda is fine for an emergency situation.

Hey Hellvis, the one on the right is a great picture Phosphorus Deficiency (P, K is Potassium).

Like some others have said, go to a hydrostore and buy a soil Ph tester, it's like a metal stick attached to a meter (get another one to measure your cocktail too if you haven't already). Also get some Ph Up and Ph Down, and use VERY LITTLE of it, like eye drop sizes.

If your soil is above 7, or below 5.8, it's a good idea to flush - twice the size of the container (2 gal container = 4 gal water), and make sure the water is Ph'd to an appropriate level (6.5 ish). If you're going to use tap water, let it sit out for a couple hours or over night, take the reading, adjust accordingly, and flush.

Let it dry out and feed again with a corrected cocktail. I'd snip off the fucked up leaves, the rest should be good.

Good Luck!
