18/12/23 - Day 12 : Watered with Magne-Cal +and another third of the easy Grow
19/12/23 - Day 13 : Noticed some yellowing on the tips and leafs seem a little less green. Probably going to just water with plain water next watering.
20/12/23 - Day 14 : Yellowing seems to have stopped, but leaves are still curling a little upwards. I suspect they got too many nutrients the other day.
21/12/23 - Day 15 : Still some yellow at the tips of the main leaves. I watered with just Magne-Cal today. I was told this stuff should be used the full grow, but after looking on the Plant Magic site, it looks like this should be used only during flowering. Can anyone confirm? I will see how it goes this week and if it looks like I'm continuing to see yellowing I will swap to only water. Ordering my PH meter today as I haven't been checking the PH of our tap water, but It's usually around the 6 mark, the last time I checked. We have great fresh loch water here from our taps.

OldStonedScottishGuystarted grow question a year ago
I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

The canoeing of your leaves suggests heat/light stress. From what I've found Spider Farmer recommends 18-24 inches @ 75% during veg for the SF-1000.

Still seeing leaves yellowing from tips and from bottom of plant upwards. Using only plain water now. What am I missing here? Other plants are starting to have the same issues. All on same feeding and watering schedule. Could this be a defitiency instead of too much nutrients?

Looks to me like they are getting to hot, taco leaves are a tell tail sing, 28c daytime with no fan is a bit much, need to keep the air moving and try and cool it down a bit. ....[][][].... RH at 45% is not ideal but is still within the range of normal in veg I like to see RH aorund 60%. ....[][][].... When growing in coir you should know it is void of nutrients and needs everything provided to it, that's macros and micros NPK CaMgS ZnFe exct.. without it the plant will suffer. ....[][][].... I think your lights height is on point now, its time to fix the feeding and get it watered. With coir and liquid nutrients you want some runoff to avoid any salt build up. PH can be between 6-6.4, there is no reason to have the PH so low around 5.8 as if something happens and the PH drifts then its much closer to danger zone of causing bigger issues. All hydro nutrients can be taken in by the plant in a range of aorund 5.8-6.8 they are readily available and work in a wide range, why limit yourself and titter on the edge of PH lockout. Use a TDS pen to get the EC or PPM of the feeding solution this will let you know how much your giving, can monitor runoff to ensure its not to much or to little. ....[][][].... Good Luck!

Seems hot and dry in your tent...I'd be boosting that humidity to 60-65% with temps that high

Thanks Ultraviolet for the really well put together response to my question.
So some things that I got from that response were.
I wasn't getting any run off when watering my plants as I assumed as they are in large pots at the start they wouldn't need lots of water. My soil, which is a coco-coir / perlite 70/30 pre-mix was also seeded with RQS Easy Boost which says that you put it in at the start, and it should last for 10–12 weeks. It also states on the site you shouldn't need any other nutrients, but they have a RQS combo pack too which they recommended using along with the easy boost. This is 1 tablet for veg and two for bloom, I split the one tablet between three plants using the water mix they recommend., It was a few days after this first feed that I noticed the leafs tips burnt, so I stopped using it and used just water for the next week, but it seemed to get worse. I ended up flushing the plants in the bath tub the other day until it started running clear. The leaves looked a lot healthier for a couple of days, but they are back to starting to yellow again, so I suspect you may be right on the idea this could be a nutrient deficiency instead of being overloaded with nutrients, which I first assumed was the issue.
I have attached a copy of my RH and Temp for the last week above to show the fluctuations in temp. Did see one huge humidity spike mid-week but seems to have settled, I suspect the huge increase in humidity was when I flushed the girls.
I have my inline fan set to go on if the humidity goes above 70, should I maybe lower this so it comes on earlier and allows the tent to dry out more?
