If you've been using RO water, have you been adding CalMag like Weedhound and others suggested? If calcium and/or magnesium were already locked out before you flushed, and you've been using RO water since, then you may still be deficient of Ca/Mg... and the Floramicro feeding may not have provided enough to balance out the levels. This is one of the biggest reasons many growers don't like MG soils, because of how much of a chore it can be to pinpoint where deficiencies are coming from.

It might be a good idea to fill out the troubleshooting form in the Plant Problems forum, and list it here. I've full faith that our more experienced growers can help you out, but they might need a little more background info on your regimens, setup, and the like. Hopefully Stinky'll show back up and drop off her two cents. She's a bastion of sound advice 'round these parts! Take care. :jointsmile:
Mr. Clandestine Reviewed by Mr. Clandestine on . Problem with new growth I have a problem with the new growth on my plants. The tips of the new growth are turning yellow almost white. They are in the fourth week. Planted in MG Organic Choice (I know I know). 400 W about 15 inches up from tops. I have used 1tsp. of Epson salts/1 gallon water twice. No change in the last few days. Seems that they have slowed in growing as well. I haven't fed them any nutes as of yet. I do use well water, could that be harming them? The PPM could be high. I have searched but seem Rating: 5
