GSC Auto - Nirvana seeds

Looks nice and growing well. I let the soil dry on top before adding some water carefully. Temperatures are stable, it's a new oil heater 😎 Challenges are maintaining humidity and gnats started appearing, not so much of an issue after using sticky gnat traps.

Only giving water when top soil is dry. Tap water is around 8.4ph. Going to work on lowering ph levels soon. One of them is a more yellowish. So challenges this week was still maintaining humidity and not trying to revive the yellowish plant. I left it alone and it followed the same schedule as the other 3 plants. The humidifier I am using is too big and powerful for this small space. There is not controller basically so humidity can rise fast or decrease fast.

Started using Hesi Power Enzyme 2-3 times a week together with Hesi TNT Complex Checking daily the soil for dryness. Temp fluctuates between 22-26C Humidity around 65% One plant remains yellowish. Still need to work on lowering ph levels when feeding.

All plants look healthy except the yellow one, although it is growing ok. The closest to the oil heater seems to be stretching the most. That's just an assumption right now.

I added a net and started using Hesi Bloom with half dose of Hesi Phosphorus Plus Lights at 100% and down to 42cm

Added another net. I think I should have waited with the first net. Does it need a third net? The most height was grown this week. It's interesting to see how quick these grow. The tallest being 70cm and the yellow which was the shortest is almost 2nd tallest. The bud density looks ok on all 3 plants except the yellowish one. Maybe it just needs more time. Edit: added last pictures for ending week 6.

Week 7 ending, looks really nice so far. Major update in hardware: replaced oil heater with AC Infinity Thermoforge T3. The temperature inside the tent is way better distributed and stays constant at 25-26c during day and 23c at night. Feeding daily since pots are 1 gallon and dry up quickly.

Week 8 ended. Nice amber pistils forming now and bud density improving. New hardware - replaced the TS1000 for the TSW2000. Currently hanging near 30cm and light intensity around 75%. Any recommendations on light settings, whether dimmer should be on 100% or lower? The light gives better coverage than the TS1000. Challenges - noticed some yellow tips so I reduced the feeding and using only ph balanced water with some CalMag 1ml per liter. I wonder if there is any use considering this autoflower is supposed to be harvested within 2 weeks. - new light raises temperature so I am still working on a better solution to lower it. Temps reach 27c

Bud and trichome development sped up during end of week 9. Since there are 4 GSC autos, each one seems a few days off from each other. Started to notice this week that some fan leaves are turning yellow. Only feeding with water ph 6.8

Week 10 was interesting, the smell increased inside the tent and it started to creep out. Wasn't sure how to resolve the issue in the first days but eventually, it was related to the fan speeds. Increasing the speeds helped a bit. Only feeding water still, ph 6.8. Removed the dead fan leaves. Challenges: Light creates warmer temperatures inside so smell was creeping out of the tent a few times. It seems all 4 plants will be harvested at different times, days apart only but is it ok to leave plants ready for harvest a couple or few days longer?
