Not 100% what to put this down to, still new to this any ideas? End of the leaves are curling under and they re folding and drooping, and darker shade of green.
5.8ph and your getting 6.2 out definitely indicates your ph is to high for your plant. Keep going in at 5.8 to 6.0ph until your getting the same thing coming out the bottom. Any time you see a young seedling cupping down like that it’s usually a ph issue.
Thanks guys great help and advice as always, my pH meter has been playing up so I bought a new one yesterday so hopefully this explains the issue, I’m going to take a pH reading at the roots now and see if that shines anymore light on it. Is it worth investing in a soil ph meter or best just doing the media in distilled water reading?
@Myfriendis410 yeah I calibrated the meter as per instructions using ph7 calibration fluid, it’s stored in ph7 calibration fluid too. It just doesn’t look too healthy especially when I compare it to the one that’s going really well. Leaves are curling and folding.
I just mixed my nutes and fed them at 5.8 as usual the run off ranges from 6.1 to 6.3 across the four plants. I’m feeding half a litre twice a day and getting half back in run off is this OK?
They are currently in 4l fabric pots was told to wait on 5th node before transplanting, do you think I should go earlier on on 3 nodes with the 4th just starting.
I like the numbers although you could probably bump it up 100 ppm. FYI EC and PPM are measuring same thing. 1.0 EC = 500 PPM. Your EC readings should have a decimal point after the one.
OK, so after chasing all sorts of possible problems as to why my leaves were curling and drooping, I do believe I was simply just over watering, I haven’t fertigated for 24 hours and got up this morning and they have never looked so perky, here’s hoping I found what I was doing wrong.
Plants are doing OK still experiencing problems and hiccups along the way but learning lots so all good, now 5 weeks old, I thi k they probably should be futher on but that’s likely down to my inexperience but I’m getting there.
Had my first crack at topping seems to have gone OK.
