Thanks for the tag D I’m gonna go the other way and say it’s over fed, problem is it looks the same as a deficiency. If you are feeding full strength now or if you are lightly feeding is what I would go by. I only go this way because the top leaves have N burn

OK GUYS NEW TDS METRE HERE. now do I need to calibrate either before first use and if so how? Can it be done without distilled water my order has been held up

I’m assuming the cal solutions were held up. Distilled would be a way to see how close it is out of the box

Brand new meters I have calibration solutions for pH when my damn distilled water arrives
Is there any other way of doing it og
Dehumidifier water could work, should be extremely low TDS if you run one in the house. Also distilled water can be picked up at most pharmacy and grocery stores. Well… at least around my neck of the woods

Unfortunately not here in the UK I’ve ordered some but they struggling to get what I ordered. Would boiling a kettle work?

Nope:rofl:
never tested
Test a tap sample and see what the TDS and PH are for GP. Can you post a pic of the pen?
