I'm using Botanicare nutrients (grow, bloom and cal -mag) with PowerSI recently added at bloom. Using RO water in a hygroton flood/drain system. Growing in my basement without heater or dehumidifier for now. Monitoring Humidity, temp, PPFD, DLI and VPD. Usually the humidity is crazy low here so I was able to use ventilation alone to manage it win the tent. Temp runs low at high 60s to low 70s slowing growth but still managing.
I have discovered that even though the nutrients were labeled as Hydro, and I diluted them to 1/2 the recommended, they were still too strong. Just started reading this thread 2 days ago and the table that @PK1 shared on managing EC and nuts on 12/5/21 as well as the advise by @Lilome on the same day, to check TDS after each addition of different nutrients was HUGE! Made the lights go on for me.
I am running a small commercial hydroponic greenhouse raising lettuce for local restaurants and thought I had a fair handle on using nutrients and growing- but the object for lettuce is NOT to bloom and I have had to unlearn things for cannabis.- So The pictures show my first grow -Critical Purple auto/fem(x2) and second seedlings- AK47 and Gold Leaf started 3-4 weeks after. Critical Purple seedlings were my first guinne pigs and 2 survived to bloom, one was stunted for 9-10 days and I left it in to grow to see what would happen- knowing that it would never reach it's full potential and would suffer because I would be adjusting everything to the needs of the other thriving plant. Still doing much better than I expected and with the stretch of the bloom it is the much taller plant now. This is the one with the leaf color changes I mentioned that were similar to yours- started exactly in the same area and was progressive from oldest fan leaves (since removed). Since decreasing TDS to low 800s everything's has started improving- obviously there was a lot of room for improvement!
Thank you. The branch I chopped Sunday due to the top molding I kept the rest and it's been drying as well.Nice harvest Clyde!
Always a good problem to haveI finally got around to dumping roots out bucket. They've been outside at the burn pit for weeks. Anyways it ate the air stones. Also ate pH meter and thermometer. It was close to an all natural grow in a sense.
Anyways getting ready to start Blue Microverse soon which is another auto. Then onto a photo.
It is, I had my fingers crossed entire time plant would compensate for anything it did naturally.Always a good problem to have
