I’m running coco/perlite and just did a flush between feeds as recommended by my nutrient schedule. To do this I ran the plant in the shower using as close to room temp water as I could manage out of the shower head for about 10 minutes until the TDS of the run off was pretty close to my tap water (100TDS). PH was 6.8. I then gave a 2L feed with nutes at the recommended 5.5PH for this week (using Cyco platinum series). This week is recommended to be reduced from the usual 6PH as it incorporates Grow XL. Run off measured was 6.4 and TDS 350.
Now I realise I should have PH’d the last gallon or two worth of flushing to ensure the root zone PH would be where I needed but I didn’t. After a few hours, I wasn’t happy with the 6.4PH so fed another 2L of nutes at 5.5 which brought the runoff down to 6.3. I still wasn’t happy with this so collected about 1L of run off, PH’d it to 4.5 and fed it back in bringing my runoff down to 6.1. I did not take anymore TDS readings after first feed.
Question is, should I leave it as is until next feed (takes 2-3 days for coco to dry out fully) or flush again now and get correct PH?
