pH of 3 and pH of 5? You are having nutrient lock out due to PH. You must flush with pH'd water.

Why wouldn't you think you pH meter is accurate if your plants look like that? If your plants were completely
healthy and your pH meter was reading that I would say it isnt accurate, but it looks pretty accurate to me.

wait til it dries out, and then flush the soil with 3 times the amount of water
your pots can hold. Make sure your PH is between 6.5-7.0 for soil, and between 5.7-6.3 for Hydro

ok, we have an older ph test kit from a pool... one of the guides says that miracle grow is ok, so we mixed up some MG at somewhere between 6.4 and 6.8 ph, maybe a little closer to 6.4...

flushing now...

hope it works!!!

thanks guys!!

flushing it is good, but another thing is in flowering the bottom fan leaves may yellow due to taking nutes and energy and putting them into the buds, usualy yellowing is phosphorous or magnesium deff if its in flowering

no, you didn't misunderstand... the guide posted on here said that miracle grow would be fine as long as the ph was right....

flushing has nothing to do about ph of nuted water , although u want ure ph of the water round 7 for soil . flushing is about removing salt build up from the soil . flushing with nuted water is like bathing in a mudhole , uve accomplished nada except burning the shit out of ure plants :wall:

Hate to tell ya bro, but pinkjackyle is right. You must rinse the salts away. Most all nutrients form salts even organics. To cure nute burn you are trying to get rid of any salts around the roots. Proper flushing of soil requires 2 times the amount of water than soil. For example: If you have a 1 gallon container of soil, you need to pour 2 gallons of water thru the container.
The water must be neutral 7pH. Distilled is the best but filtered will work fine.

You will have to sacrafice the container its growing in but.... Take the container outside, poke MANY, MANY HOLES in the sides and the bottom and flush again with the proper water. The holes are VERY important. After running twice the amount of water thru, take the plant and container after it has drained and get it somewhere you can get humidity down pretty low. It needs about 40% humidity for a few days. once the soil has dried a bit, set up some new soil. You dont have to spend a ton of money on your dirt if your not sellin!!!!. You can use any store bought POTTING MIX. not top soil, not humus, but potting mix. A huge bag for around 6 bucks. fill the pot up with the potting mix and water till soaked. Wait 5 min. and water one more time. Wait 30 min. and transplant your plant into the mix and keep the light a little further back than usual for a couple days. It will be fine!
