7/12/23 - Day 1 : Amazing how quick this seed popped from Royal Queen Seeds. It was in a damp paper towel in a zip lock bag overnight around 12 hours in a dark drawer, and it had popped and started to grow a tap root.
9/12/23 - Day 3 : Transplanted directly in to 11l pot with 75% coco & 25% perlite pre-mixed soil from our local grow shop.
11/12/23 - Day 5 : Up and out of the soil like a rocket. Looking healthy and active. Great start.
11/12/23 - Day 5 : Watered with plain Scottish tap water, 200ml around the seedling.
13/12/23 - Day 7 : Watered with plain tap water as soil was dry.
15/12/23 - Day 9 : Split the easy grow booster tablet up in to three and added to 1.6l of water and used a third to feed this Hulkberry and the other two thirds to feed my other plants
18/12/23 - Day11 : Fed with the other third of the easy grow booster tablet and about 500ml of water
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.
23/12/23 - Day17 : Tips are looking a little yellow again, I really need to follow my own advice and go completely water only on the next watering. No Magne-Cal + I think the RQS organic boost is enough without any further nutrients at this stage.
24/12/23 - Day18 : Tips are more yellow and a little bit of curling upwards. I have done a full watering with 1 litre of plain tap water with no Magne-Cal + this time around to see if I can flush some of these extra nutrients that I think are causing this.
25/12/23 - Day19 : Merry Christmas and she has taken another boost in size, but still continuing to see yellowing leafs and some curling of the leafs upwards. Google suggests this could be heat stress or nutrient burn, so I have stopped using nutrients for now and have moved the LED lamp to further away from the plants. It may cause stretching, but I suspect that's better than burning, who knows, this is all guess work for me at the moment.
I'm going to try the questions function on here to see if I can get some ideas on how to resolve these issues and see if there is anything I should be doing different.
26/12/23 - Day 20 : It's just another day, but they look healthier already from just using water and nothing else. I have also raised my lights a little but going from Scrubbyjimbob's advice in my questions I am going to raise it quite a bit more in line with spider farmer's recommendation which I wasn't aware of. Also, m0use's advice regarding heat management and diluted nutrients was good. I have adjusted the tent somewhat, I have removed one of my big fans and kept a small usb fan to circulate air and turned my inline fan up to produce more airflow which in turn has reduced the temps down to about 28c during light hours. I have also adjusted my home assistant automations to turn the fan off if it gets too cold or dry and back on again when needed. I find my nighttime temps are quite a bit lower and my humidity quite high when the lights are off, but I guess that's because the LED is no longer producing heat, which evaporates the humidity. All guess work here.
27/12/23 - Day 21 : Going into week 4 strong. She is looking better with just water again today. Let's see what the next week brings. Starting to consider LST as I hope to see a big increase in size this next week. Maybe put up the scrog net. What's people's thoughts on topping autos? Is it worth it ? My tent is small so it may be a good shout.
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?
29/12/23 - Day 23 : She has taken a stretch since raising the lights, but I am still seeing discolouration, I am also seeing the same in other plants that are growing under the same conditions. Going to ask another question as it seems to be getting worse than better.
30/12/23 - Day 24 : Fully flushed all plants to see if I can nip this yellowing in the bud, got some great advice on here to try too.
31/12/23 - Day 25 : She has taken a stretch, this may be due to the flush and the raising of the light. Fingers crossed for some more growth this week.
01/01/24 - Day 26 : I'm still seeing some yellowing, but I decided to do a little LST today to see if I could get more light on the lower bud sites.
03/01/24 - Day 28 : Due a watering today but top layer of soil is still damp from the flush, will hold off another day and se how it goes.
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!
