D22. Starting the fourth week of veg, and everything is just trucking along in the tent. However, I noticed how the first girl curled her leaf edges (taco-ing) at the end of the day. That indicates that she is getting too much light, so she is making herself smaller to limit the amount of light. The leaves also droop away from the light, indicating that she has had enough. I reckon that the jump from 25 DLI to 32 was too much for her to handle, so I raised the lights until I measured 400 PPFD at the canopy level. That translates to a DLI of 26, and I will let her stabilize there for a few days and then slowly raise the DLI every two-three days until I see some light stress again. At that point, I will back off just a smidge to get the maximum amount of light the girls can handle without getting roasted. ------------------------------ D23. The girls were getting a bit thirsty (around 120 mbar), so I decided to brew a quick compost tea and give it to them. My old set-up had gunked up, so today, I replaced it with a much more powerful system I built. The good news is that it is plenty powerful, and the bad news is that the pump is too noisy to leave running overnight. Not a massive deal as I can start brewing in the morning and then use the tea before bedtime. I mixed worm castings, rock dust, biochar, lime, bentonite, kelp, and neem meal, put that mixture in large tea bags, and let them steep for 10 hours in water with a bit of molasses as food for the microbes. Finally, I added a bit of humic acid and adjusted the pH to 6.3 before giving each girl around 2 liters of tea, which works out to around 5% of the container volume. I also diluted some of the tea and used it as a foliar spray just before lights out. ------------------------------ D25. The first girl bounced back from her light stress and is now looking great. I will give her another couple of days to settle and then top her for the first time. I've decided to scrog this time instead of main-lining. I'll save some veg time (and electricity) that way. The second girl is playing catchup but is looking vibrant and strong. ------------------------------ D26. The first girl is still showing a bit of light stress towards the end of the day. Have to keep an eye on that. I did a fulvic foliar spray just before lights out. ------------------------------ D28. We're at the end of week four of veg, and the girls look great. I was going to top the first girl today but didn't have time. I'll get to it tomorrow. ------------------------------
