Hey everybody I'm new to the whole liquid fertilizers and im using the fox farm line right now, the issue though is that the first time I fertilized I sorta fried my babies and had to flush the soil to get rid of the excess before it got worse. So now I have a tds meter and am trying to dial in the fertilizers im using do this doesn't happen again. Basically im wondering what a good concentration range would be if I'm mixing a gallon of distilled water with my fertilizers so that they get what they need without the burn? I'm just entering the flowering phase on my Cinderella jack auto and my glueberry OG auto and they seem healthy and everything but I want to fertilize them now without causing issues. Any help with what my ppm measurements should be would be greatly appreciated
 
Are you growing in soil?
Why are you using distilled water, is there something wrong with your tap water?

With liquid fertilizers, more often then not the feed charts are way to high of dose. I recommend using 50% of what the feed chart says, the plant will tell you if it needs more or less of something.

Yea im growing in soil, I'm using distilled water so that it doesn't have the chlorine in it and I don't have to go through the hassle of dechlorination before feeding although sometimes I do this still. I've also been making sure to balance my ph it's just getting the nute levels dialed in because like you said the feed charts seem way to high at least for the strains I'm growing
 
Does your water smell chlorinated at the tap?
In soil ph balance is useless. Don’t need to feed cannabis in any regard until the end of week 3

You have a few issues here.
If you water is highly chlorinated then fill a jug and let it sit with the lid off, 24 hours later it’s fine.

Stop using distilled immediately
 
Pics of plant are essential, as well as your soil type

Keep your N up for the next couple weeks. That cindy jack auto should produce, phenomenal growers, great smoke too

Ppm of nutes in soil isnt really required. If you have a fully established plant you should be somewhere around 80% of dose depending on your soil
 
Here's a pic Cindy on the left glueberry og on the right

Is distilled bad for them or is it just stupid and expensive? Haha

You don’t.need to worry about ppm’s in soil, also chlorine is not an issue particularly in a syntheticc grow. Chlorine will kill some soil organisms but their numbers rebound in a day or two. Does anyone dechlorinate the water they use in their gardens?

It's another cost you don't need but it also has nothing really beneficial in it for the plants. Using distilled or an RO system takes all the beneficial minerals out of the water.

I use to buy distilled water and it got expensive, especially when they started guzzling in flower. My plants also never looked 100%, I started using tap water and I literally could see the positive changes. Just my personal experience but if you can drink it, so can your plant.
