Grow Mediums Canna coco ph and ppm's in run off

[Ross3k]

so my seedlings have hit day 10 I've had a few issues which looked like a lack of nutrients so I started a 1/4 feed of coco a and b, they seem to look better, didn't get any worse anyway, before the a &b (day5-6) I had given them a 1/4 feed of canna start and rhizo.

My question is I ph my water to 5.8 and ppm has never went over 250 but my run off is ph 6.9 and ppm are 350-370 ?

Canna coco pro, brand new out of the bag mixed with pre washed perlite 70/30 mix.

Any ideas ?

Light is a optic 4 led around 40 inches from plants..
Autos, 4 different strains (just to make life harder hehe)

not too sure what the issue is with the high ppm runoff and ph maybe its just a bad bag of coco and needs a flush out with some 5.8ph water that what i would suggest doing just run all the ppm out o the coco and get your ph back to norm then start adding back in your feed but this is just my opinion im no expert just telling you what id try im sure there are some people around here that will help out make a post in the infirmary section or sick plants and some like @Waira or maybe @blue coul help hope you can get it fixed

I'm just worried about the run off, surely with little amount of feeding it shouldn't be coming out higher and the ph rise puzzles me.. did I maybe water to much in the pot and a lot of the nutes were unused by the plant due to size and have built up slightly ?

just seen your pic they dont look bad atal im still going with PH being off leading to low uptake and a higher runoff ppm

Yea that's what I was thinking try to flush it down to good readings but because coco I was unsure how to go about this, flush as normal with just ph'd water then go back to 1/2 feed next day or same day ?

Not looking too bad now, slightly off colours, you can notice some spots on the last pic and some curling at the sides of the leaves on others, just the readings on the run off have me confused

yea just flush with normal ph water no ppm untill you get the right ph then run about a liter of a light nute mix probly half or 3/4s throught the coco so the plants dont get startved and then resume your normal feeding for the next watering coco is very fast compared to soil results can happen in hours instead of days
