Yellowing leaves and burnt tips.

[THC Prince]

If you don’t want to flush I’d suggest just water only the next couple of waterings ph’ at 6.0 and see how they go after that. Maybe use quarter/ half strength nutes after you’ve done the water only.

Would also be worth reading up on some basics for growing cannabis for any future grows, that should prepare you for problems like these arising again.

All the best

I had to add PH- 7ml (10 liters of water) to get it down to 6 Before PH- it was 9.

I have been making lots of readings and notes but every time I have the same problem .... nitrogen toxicity first and after that yellowing. I have tried different soils. Next time will buy other PH- and this digital Pen.

Anyway, 9 weeks and grows pretty ok:
