Should I worry about waste water having very high PPM?

[BlueBucket]

Hi hello .. I'm into week 5 of the bloom cycle using Cyco nutes (Bloom A & B, Zyme & Swell).  Hydro, run to waste in coco coir and perlite mix (1:3 ratio) .. using 2 x 600W HPS Cultiv8 digital ballast, heaps of airflow .. air conditioned room, SCROG .. top of canopy usually between 27-30 degrees with around 70% humidity.  Have 4 plants, 3 strains (next time will be sticking to just one strain!).  The plants all look very healthy with buds everywhere .. but the waste water coming from the Blueberry plant is giving really high PPM readings, between 3.50 and 5.60 .. which seems really odd to me considering only 2.10 PPM nutes are going in.  The plants are all flushed weekly with PH adjusted water.  Should I be concerned about the Blueberry's plant's waste water high PPM reading?  Have I goofed?  This is only my second grow and I can't find anything on the web to explain what's going on .. I thought maybe algae, but can't see any and am using black water hoses and black plant 'socks'.  Can anyone offer and advice?

Ppm I don't read I use EC but if it's higher than what your putting in give it a flush at a lower ppm till it's adjusted itself .

 

Prob would do better with a ph water flush then back to normal ppm ,

 

 

I just got two Cultiv8 ballasts .only using one at the moment and fuck is it hot. Bloke at the shop said he's heard of it happening before so he said he'll take it back . Is your ballast hot to the touch ?

Cultiv8 burns shit down, mates caught fire, he wasn't home would of lost his house, wouldn't piss on them

 

every ballast should get checked every week, plenty houses have burnt down over the years

Hi Serrated edge .. I have flushed .. and flushed with PH adjusted water.  After each flush it starts out ok, then jumps straight back up.  It's a mystery to me .. must be algae in my system somewhere.  But anyway, I'll flush it again.  And yes, my cultiv8 ballasts run warmish.  I have them sitting on bricks outside the tent.  I haven't heard of them burning houses down though .. bit odd since circuit breaker should trip if it faults.

How many litres did you flush with ?

[BlueBucket]

I was flushing with around 60 litres for 4 plants in 40cm pots .. until their waste water was down to around 800 PPM .. our water here is 400 PPM.  Flushing water was adjusted to 5.7 PH

[BlueBucket]

I've decided to flush it again tomorrow morning as I've just tucked them in for the night.  I'll post back tomorrow pm with result.  Thing is, the plant is doing really well regardless .. sheeesh!

[Serrated edge]

Are you allowing a decent runoff each time you feed ?

 

A 10-20 percent runoff acts as a constant flush .

 

In any case sounds like the berry wants a weaker feed than the others , my guess is she's taking in more water than nutes ,,I'd give a good flush again ,,then try feeding her about 30% weaker nutes.

[BlueBucket]

Maybe I wasn't allowing enough runoff for the berry .. it's the biggest plant.  Will take your advice and give a good flush tomorrow morning and reduce her nutes by 30%.  Thanks Serrated Edge .. it's good to have someone to 'bounce' off as I'm new to this and am still learning stuff .. thank goodness they are tough plants!   This grow will be better than my first attempt, but still got my training wheels on and get nervous, so appreciate your advice.

Just keep an eye on her and the others ,,if you get burnt tips on the leaves then the nuts are just a bit high .

 

More than often they do better with less.
