I am new to growing and made a rookie mistake by not testing the ph of my peat before planting the seedling so I have been trying to lower the ph with white vinegar which I already had on hand. After around day 5 it started to come down closer to 7 but then I stupidly fed it some Reiziger nutes which I picked up from my local growroom shop. After only 1 or 2 days of giving the nutes to my plant it started to develop light yellow marks and some of the tips are showing signs of nutes burn. Also appearing today are a few brown marks around one of the leaves edges.
On another note. If you’re using purely peat to grow in it’s very acidic and that could be why it’s not rising. You would have to add dolomite lime to it and it would be a constant battle with your pH. My advice would be to go for a more cannabis friendly soil
@GoodMafia interested why the ph is still unknown for now? I have been using the rod type ph meter reader (it’s in one of the photos of my plant) are these also not very accurate? That is what I have currently been using to test my soil ph.
Yeah those cheap probes would probably say 7ph in battery acid. The moisture probe is the only thing on that device that can tell you anything. You can purchase real expensive soil probes that can be accurate. It’s just easier and much less expensive to test your runoff ph with a good digital meter to find out where your soil is at. Or by performing a slurry test with a digital ph meter.
This is actually a standard starting mix. I have purchased bags of the same mixture for starting my seedlings. Peat does become acidic over time…its not instant. But coco goes the other way which is why the mixture works. Feeding a seedling is not necessary and in fact it looked ok at first. As was mentioned just go back to plain water at the correct pH.
Thanks @Spiney_norman thats good to know that I have the correct mix. I will revert back to plain water for now and visit my local growroom shop to buy a good ph reader. From what I gather I have probably just entered the veg stage so how much longer do I need to wait until I need to introduce any nutes?
Yes, just plain water now untill you get your meter and then start out slow.
They look like fine nutes, just follow their schedule and watch for issues. Each plant can be different.
I have 4 in my tent right now. One is thriving and one is starving. Feeding exactly the same thing, one just seems to need more food.
