FC3000 SLH GHS 1st DWC

Welcome to my 1st DWC grow, be sure to drop a like so I can visit your grows. Wk 3 VD15 Growing, a little slow but it's growing. Its very clear this is my 1st DWC grow. Having real issues with temp for water even though the air pump is in a colder room at 21c. 21-24c too high. And it's showing in the roots. 18/5/22 Figuring out how VPD works. You could read for hours about this stuff and still not dial it in for years. But here's the basics. VPD 0.4-0.8 kpa for early seedling. So under or around 23c and around 50-60 RH. atm my VPD is 1.05kpa and for most of my plants the optimal range is .8-1.1 kpa. Temp is 80 F 25-26.5C and RH is 70%. To find the perfect VPD (Vapor Pressure Deficit)check out optimal ranges of VPD for growing stages, also your strain should have the optimal VPD. I don't have an infrared temp to check the LVPD (Leaf Vapor Pressure Deficit) that's a whole other ball game Checked PH was 6.5, adjusted to 5.8 with PH - crystals. Seems to keep a more stable PH for longer and doesn't mess with the PPM. IDK if it's good or not but the PPM has stayed the same the past week, May be dropped by 10ppm. Just the PH keeps going up. So, my meaning is it's drinking and the PPM is set just at the right level. As I've not filled it up since I put water into it. And as it's drinking the nutrient mix it's taken everything up and just leaving the PH adjuster from the nutrient additives. If the PPM drops I will not that I need to add a little extra nutrient mix. Decided to add Fire Yields, It was meant to be given the 1st 2 weeks, but I was given a chart that says on week 3-4 so I didn't know, so it got started now. Plant seems to be doing ok. Bit droopy, but has steady growth. Having real issues with temp in my tent. It's 26.5 with lights on and 22 with off. If I wasn't doing photos I'd be doing a 5-1 light time on/off. As the water is a nightmare to keep under or even close to 20. I just can't get there. 4 times a day I'm having to add full bowls of PH'ed water. It's a poxy pain and I can only get it to stay at 22. Only thing, these enzymes aren't meant to go bad until they reach 25 and there's always a degree or 2 you can push them. But I also know there's other bactria that will end up coming. I'm only going to run enzymes until I get a decent root structure and I'm getting there with this 1. The mystical green has made a kind of black stain that easily wipes away from the roots. I'm not going to bother washing them, as this is stuff to keep a stable environment and does a lot more. So it's going to be given threw the whole grow. Having to adjust the PH every 48 hours back down to 5.8 and I adjust it when it reaches 6.3-4. At the moment I'm just adding PH - crystals. It holds a steady PH longer than liquid. 48hrs but I haven't pushed it past that. As she gets bigger and drink a more I'd say the amount of PH adjusters from all the different nutrients that will be added and the more it drinks it'll leave more. EC/PPM hasn't dropped at all so it's still perfecto. But I'm thinking that's going to also drop soon. The roots are deep. Hoping for big changes this week. I won't be changing the water for at least 2 more weeks now. I'll add to it but I only added fire yields and I'm not wasting 40ml of it so it's staying for 2 weeks. I will give the roots a light wash though as I don't want their little side vain roots getting clogged up. 22_5_22 Decided to FlMing, done the 6th node coming up. If I done. 23/5/22 Done defoliation. Some light sulfur or calmag def. Have added calmag and sulfur. That's it for this week, other than pics of the rest of the week and I'll take root shots also. Thanks for reading. gottagrowsometime
