The first thing I do when I have an issue is check the soil ph and tds. Just because you’re feeding say 6.5 doesn’t mean the soil is 6.5 I learned that the hard way. Also if the tds coming out I really high then a flush may be in order but if the tds is close to the feeding tds a flush is not a good idea.

Thanks, that was the problem 
, runoff pH was 5.40, so Calcium is not available at that range:
360 ppm (0.7 EC 
) so apparently no salt buildup, I think my mistake was adding pH down to the dehu water (6,8) thinking it was the tap water (7.4), had measured 2 drops per 10 liters and never checked the pH thinking it was OK, lesson learnt, thanks for your help …

I did the same my last grow…watered 6.2 to 6.5 but got nute lockout as soil ph was 5.5
And how did you manage to correct it, flushing with pHed water? You mentioned it’s not a good idea if TDS is close to feeding, which may be my case …

No need to flush just start watering with 7.0 water and retest after a few watering. You should see it climb just a little after each watering. I do like to get a little run off but nothing crazy.
Once its back in the proper range go back to your previous ph. I will say you can definitely increase you feeding a little with only 300 tds.
This is middle of the road which is plenty imo. Less is sometimes more.

Thanks, half of them are sativas which I was told to feed low, so I give the same to the rest as they’re mostly finishing and didn’t see any fading on their leaves. I don’t water until runoff to keep dry their feet and humidity low, I also tend to avoid salt build ups while feeding low …
