Yeah, but you're running RO water anyway, so that shouldn't be a problem. What do you pH your water to after adding ferts and all? Also, how did you come up with 6.0 for the soil pH? If your soil is indeed 6.0, you have to fix that until your plants will even bother taking up P, Ca and Mg. A lot of growers make the mistake of assuming they have a deficiency, and add more nutrients, when really, they are dealing with a nutrient lockout.
I actually just misted two with a tsp of epsom.. and I was misting most of them last week.. seemed to help a little but nothing major. I actually gave them a foliar with just water the other day to kind of clean everything off.. they looked less happy after. So perhaps they were liking the extra Mg.. Im just trying it on the worst two now.. trying to gauge reactions.You could try a foliar feed of magnesium (epsom salts) on one plant. If you see a rapid change (12-24 hrs) ....start to bring up your ph to allow the nutrients that you've been pumping in - to actually be used. And...then watch for signs of excess!
Just do one at first, so you can easily compare to the others.
I know everyone says at lights off...but I've never had trouble misting w lights on as long as I set the 'wet' plant a little closer to the fan to make sure she gets dry pretty quick
The soil seems to be testing at 6.0 with a rapitest kit & also when I soak some soil in water and test the PH with my meter that way.. I was not until recently testing my water PH but started after this issue never had problems before.. strange, anyways I noticed the 5ml of cal mag was dropping my RO frm 7.0 to a 5.5 so now I'm adding PH up in a natural form to bring it to 6.5ish
People will have an issue and they say it hasn't been a problem before. It's never a problem until it becomes one, ya know?
Dude, you need to rule out nutrient lockout. You shouldn't be fertilizing them right now, foliar or otherwise. Rule out nutrient lock out or you'll just run it to bigger problems. Trying to help ya avoid that.
Right, but even when I test the soil out of the bag still getting a 6.0 PH. From what I understand this soil does not have much lime in it and its common people adding dolomite lime to HF & OF soils? although I never have and kind of just used cal mag+ starting to think I should be amending it to buffer that PH better and get the extra cal mag too?? Also yto me if you look at the leaves they look light, more lacking then anything? thanks for the input.Yeah, that's good. I would actually think about flushing with 6.5, testing soil again, and then going back to your feeding schedule. It's possible your soil is buffering to 6.0. In that case, you'd want to think about adding some soil amendments, and it can take a little bit for that to have effects. So hopefully, it's just your input water being at 6.0. I understand you haven't had problems before, that is common. But, when pH isn't checked and everything kept dialed in, this is what happens.
