2 of my plants are doing this pictured below. The plants have been though alot of stress from the get go. First off I started out using 200ppm tap water and well you can probably guess what happened. Too much Ca and Mg in the and me getting too carried away with nutes too early burned them up so i bought a RO filter setup and now my tap water is 20ppm and 7.0ph. Then i changed the water about 1 week ago with ro filtered water and 20ml of AN B-52 in 5 gallons of ro water. They all turned around and started growing like crazy. now the new growth is looking sick.

What's your current pH? With little buffering ability, reverse-osmosis water tends to fluctuate wildly up and down the pH scale depending on the source of the water.

A downward and inward curl to the leaf tips like that makes me think that it's a lack of relative humidity, though. The red stems scream for more phosphorus, and the green looks so dark that there may be too much nitrogen also.

the Ph seems to stay right at 5.8-6 and dont seem to fluctuate too wildly. It is only happening to 2 plants out of 10 that are all the same strain. I barely had any nutes in the rez at all just 20ml of B-52 added to 5 gallons and ph down. witch is about 1/8th strength from what they recommend on the bottle. but now that I think about it I added a little too much ph down so I added ph up to get it back to where it needs to be. Is this a no no adding ph up after you added ph down?

 

[Dr. Detroit]

Do you own a meter?

It's a necessary investment for any hydroponic or aeroponic systems.

yeah I own a ph meter and a TDS meter ph stays stable at 5.8
