What is wrong with my plant? It is turning yellow

You can see in the picture that my plant is not doing too well. I recently transfered it from miracle grow moisture control soil to a local brand organic soil. I flushed it 5 days ago and did a semi-flush 2 days ago. It was not this yellow before I flushed. I use filtered water that is delivered in jugs. I have a cheap ph tester and I keep the water around 6. Any ideas?

ph is way too low, you need to be above 6.5 but below 7.

should I flush it again with the correct PH?

Does anybody know how I can clear this problem up?

you need to get the soil to the right ph so yes flush it with the correct ph while remembering to not drown the plant. Give it a few days of TLC and it should get better.

add some nute in there . it look hungy

I'd be reluctant to add more nutes until it recovers. That new soil will have plenty of nutes to keep it going until then. Your ph of 6 will have been locking out P, Mg and Ca and possibly even N and K which is why she looks the way she does. Get the ph sorted and you will see a rapid improvement.

its over watering mate! water when the top 1-2cm of soil is dry, cannabis love wet/dry periods.

also could be a nitrogen deficiency but probaly not lol

cheers

The plant is still very wet because I gave it about 3 gallons of water to flush it two days ago. Will it be safe if I flush it again with the correct PH? will I drown the plant if I do this again?

How much water do I have to give it in order to raise the PH?

ph does not depend on how much water you give the plant per se. You need to adjust the ph of your water or water-nute solution before giving it to the plant. I'm wondering how accurate your ph meter is, as a value of 6 for pure water seems very low to me. For example there is a legal requirement for tap water where I live to be at least 6.8 as anything below that is considered too acidic for human consumption. You should make sure your water's ph is between 6.5 and, say, no more than 6.8 before watering. If you add nutes to the water this will lower the ph, so check it again after the nutes have been added before watering (again you should be aiming for about 6.5). In order to raise or lower the ph of your water or water-nute solution you can buy "ph-Up" and "ph-Down" which you add to the water or solution in very small quantities to adjust the level.

However, the most important thing is to keep an eye on the ph of the soil itself, as ultimately it is this that will determine how well your plant can take up nutrients. Check the run-off from the plant, ie the water that comes out the bottom of the pot when you water. This will give you an idea. If you find the soil ph is too low, then perhaps raise the ph of your water or nute solution before watering, or if too high do the opposite, and then check the soil ph again. If this doesn't alter the soil ph sufficiently you can add various things to the soil mix to achieve a "permanent" change in ph - see GROWFAQ. [NB: A lot of the guides on here suggest a soil ph of 6 - personally I think this is too low as at this level trace elements like P, Mg and Ca will be locked out. Go for 6.5.]

Finally whatever you do to alter the ph do it gradually. If you create a sudden large fluctuation you will cause your plant to suffer ph shock. Slowly but surely is the way.

I hope all that was clear LOL. I'm not an expert on this, just trying to share what knowledge I've gained from other users on this excellent forum.
