Hulkberry first ever grow

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.
