Any solution????

So guys im groing in Canna cooco professional plus soil , im not too informed about soil thing

i did a run off test of just the new soil with just water ph at 6.5

the run off ppm was 1.4 which I understand that are nutriens in it but the ph run off came out 5.7 , and i planted some clones about a week ago and i saw some nitrogen toxicity and i did a run off test on them and was completely out of control some of them were too high with the ppm and too low with the ph

how comes this happen cos im having this problem evertime and i need to flush plants afer a while so after that a can control the ppm and ph till the end

Have you been feeding them anything? If yes, then start watering to 15% runoff. If no, are you using tap water? Tap water contains minerals that can build up over time, altering ph and ppm readings.

Nutrient salts lower ph. The more they build up, the lower the ph. You can feed less, or water to 15% runoff to fix it.

If you feed to much then yes. Think of it like this, the water carries the nutrients to the roots. When the plant gets full on nutrients it only needs the water. It uses more of the water than the nutrients and then the salts are left behind. When you initially water the solution is at the proper ratio of minerals to water. Over time there is less water and more nutrients in the mix, thus ph drops.
