Hi @StealthAlien Tap water is usually around 7-7.8 PH. fertilizers tend to lower the PH, you can apply the nutes normally. good luck mate 👍

At this point prob ok do you know what PH your water runs?
Mine runs between 7.2-6.8 so I kind of know how much PH down to add (almost said up constantly doing that).
You will need a way to test soon though even the dyes would do well enough.

Calculating Proper Runoff NumbersBefore I watered plants today the Ph was 6.0 and 1,000 ppm. I added nutrient solution of 6.2 and 1,000 ppm to each plant until runoff. Runoffs were 1,300 to 1,700 range. Ph was 5.9. Is this in the ballpark. If I add 1,000 ppm to existing 1,000 ppm and get less is that right?Week 10

How long left?Hey all, first grow seems to be going ok, despite me being clueless!
Now at 8 weeks and 2 days and wondering how long I’ve got left? RQS say 9-10 weeks total.
Still a bit to go - only a few hairs turning brown but would really value input on when to stop nutes?
ThanksWeek 8

Today, I switch a few over to Professor Bruce Bugbee's soil-less mix :
50% Vermiculite
50% Peat Moss
(& some gypsum and dolomite lime..)
However instead of using Vermiculite I put Perlite, like an idiot!😜
Should that be fine until ready to transplant to super soil in due course?Week 2

Nutes after transplant and spring waterHello, I have recently transplanted my green friends, is it time for me to start using nutes or should I wait for a bit after the transplant (possibly stunted)? Also I'm using spring water which is 0.0 EC, should I always use calmag to raise it up to 0.6 EC before adding nutes?Week 2

Coco and Worm Castings - Does Total Dissolved Solids Matter?Does total disolved solids (TDS) matter when growing in coco, worm castings, and organic dry ammendments? Am I at risk of a build up of salts? I have seen 2700 ppm in my current grow, but are these simply not salts and therefore OK? Plants look good happy. TY5y ago

Bad case nute burnOne of my blueberry plants is going through a bad case of nute burn, I only realized it when I checked ppm runoff and it was 1200. Will she survive till harvest if just fed with ph water. The others aren’t nearly as bad and I’m 2 weeks out from harvestWeek 9
