Number that need explanation plssssss

So last night was the first time I measure TDS, I added fertilizers like I normally add and measured the TDS it was around 350 ppm so I figured out I was adding too little.

I got two plants out and flushed them and measured the initial run off TDS was 300 PPM... I put them back on their trays and back to the tents, when I went to feed the plants I measured the remaining run off on the plants I flushed and it was 5000 PPM yes 5000 PPM. PH on the run off water was 6.5 same value as the water I used to flush.

What do these figures mean to you, why, what do you advise?

If the runoff was actually 5000 ppm your plants would likely be dead. Maybe your TDS meter has gone bad.

run off means nothing, read the plants. don't create issues where there are none. if plant is happy. that is what matters. Soil has Ph buffers. less is more.

I tried it again on the water I use at gave accurate reading. It's still new I just received it last night.

except for the one, they look ok. I would look more at a bug problem. a scope/loupe would help.
