Second opinion

[LewisR19]

Hi guys I’ve noticed a issue on one of my plants out of the 6. I’ve got a few slightly twisted leaves and the plant itself is looking a little pale to me considering I’ve upped the feed it’s getting to 2ml canna A/B that gives me a EC of 1.8 and pH to 5.8/5.9. I have just measured run off and EC is 0.8 and pH is 6.8 so making me think I have a build up?

Plants are Photoperiod Tropicana cherry in 20L canna coco getting about 3/3.5L a day in drippers until run off

Flood the pot with a feed solution Ec @ 1.4 and Ph @ 5.8 till the run off comes out @ Ec 1.2 and Ph @ 5.8 might take a good few litres to get there...Alternatively flush with plain tap water till the run off valves matches what went it then resume normal feeing..You might need to do this on a few successive days to balance/reset the medium...

Forgot to mention...Check the root ball if you can, your looking for a good occupancy of the pot and roots are not rotten or smell funky eggy smelling..

Thanks for that Bud. I will go double check that my meters are calibrated still and il get to that right away would you recommend me do this with only the plant in question or all 6 as an precaution just incase? appreciate it big time

If you have 6 plants it won't hurt to reset the medium for all of them as a precaution..I do this a couple of times during a grow, it's standard practice for me. That's the good thing with an inert medium like coco you can start with a fresh slate whenever you like...Flush 3 x the pot size with plain non pH adjusted tap water, when the pots have drained a bit go in with a couple of litres of feed solution per pot, pH 5.8 Ec 1.4

Ok mate thank you. It seems to be every time I use drippers I get a issue and soon as I go back to hand feeding and flooding the pots everything is sweet

Are you water/feeding run to waste or recirculating the run off back to a reservoir ?

Run to waste

Here’s a full pic of the plant in question, unable to get a look at the roots but fresh white coming out the bottom

Plant don't look too bad on the whole...Not worth bothering with drippers if your run to waste mukka..6 plants is 12 to 18 litres per day or 2 to 3 litres per plant, hand feeding much better, I use a jug and pour it straight in, flushes old stagnant unused crap out and draws fresh oxygenated nutrients past the roots helps prevent any salt build up...

Yeah I think il bin them off and go back to hand watering, only reason I wanted drippers is to set a timer so they get fed the same time daily due to work commitments but I suppose a few hours here and there won’t harm
