Looks like the autos are in full flowering. Oldest is 41 days today. One of the GSC has done a full stretch and grew 2" in several days. Still struggling with Temp and Humidity. I have a Mendel and just cannot get the VPD down. I have 2 300W LEDs, and have been throttling them back. Room is 76F and cannot get any cooler.
Going to set up a CO generator today. Have no way of measuring it, but I have the dam thing so hell it can't hurt.
I have two photo clones I bought. They are little topped and LSTd bushes right now. Will go to flower in a few weeks as we will be out of town for a few weeks, and do not have anyone to manage them. Growing is a be home commitment.
I put Bruce outside for a few hours in the sun as it has always appeared over watered. Trying to let it dry out more, but I think it might have some root damage.
Plants have been getting RO water PH 5.8 and lately with a dash of Seaweed, Cal Mag, and Molasses. Brewing my first tea: 1 Tablespoon/Gal Seaweed, Cal Mag, and Molasses, then tea bags of cow manure, and worm castings.
By the end of this week I started to see yellowing leaves on the bottom. Some classic signs of deficiencies. I started the bloom formula and the plants have really loved it. Everything is green and buds are coming on strong. Now Froot by the foot is the only one really showing a frosty buds.
End of the week update. I put in some bloom with the feed, and then the next day top dressed with 4-8-4 and worm castings. I think the yellowing has stopped. Certainly slowed down. GSC is now 25". Lifted the lights as the heat is killing me. See the tips burn on GSCs a little which is Nute burn? or maybe heat. Still have a tea of Liquid seaweed, molasses, and cal mag brewing. Will add light bloom and feed when the plants are lite. The two veg clones I have going are spread beyond the 3 gal pot. Plan is to harvest the Autos, then transplant these into 5 gal pots, get the net set up and flower them maybe in August. Did my first clones into a propagator. Going to give those away, and keep running clones.
Hey there friend looking at your diary, Would you be alright with me offering some pointers? So cannabis plants LOVE heat and humidity. It is the buds that hate it. In veg we want to take advantage of this fact to help our plants grow along much quicker and more vigorously. In veg we can look for temps of 79-84 MAX with lights on & no more than 9 degrees less with lights off. If we allow for too much temperature swing between lights on and lights off while the plant is still growing vertically up to day 20 of flower, We will cause the plant to stretch ALOT which we do not want. So in veg & early flower, Keeping our temperature gaps nice and close between lights on and off is key. Utilizing humidity in our rooms during veg will also help out a lot with more rapid growth but we must introduce it properly. In our rooms we have our temperature and humidity set-points, But when we combine those 2 it forms a third set-point which is the most important & that is called VPD, Vapor pressure deficit.
I strongly recommend every new grower or old grower who has not learned it yet, To study and understand it & implement it into your room, Logging your numbers daily.

For soil, We generally want to go for a PH of 6.1.
This website does a GREAT job of illustrating it with a nice graph & very good detailed explanation for soil.

As we briefly touched on before, During veg & early flower we want our temperature gap's nice and tight to avoid stretch. Why exactly our plants stretch in response to this is a genetic trigger being activated by the environmental stress essentially telling the plant the end of the season is closer than it really is. In veg & early flower the plant is still in its first stage of development which is to grow up wide and tall so when it produces seed, It can cast them out nicely. Remember, Whether we are growing our plants for seed or bud their genetic responses do not change as they gh sidedo not know any different. Once the plant has finished that first stage of growth by weeks 4-6 of flower with most strains, It is by day 20 of flower. Autoflowers you have to watch for it, But once the plant has finished this goal its new mission is to focus 100% on producing nice big flower clusters & to get very sticky so it can attract pollen to it successfully.
So once that vertical growth is finished, We actually now want to begin to expose our plants to larger temperature swings between lights on and lights off. This will help activate that genetic response and allow us to draw out the most potential from the strain utilizing the plants genetic triggers to environmental stresses at the right times. We can also take this a step further with doing light deprivation in the last 2 weeks using less light to simulate cloud cover. Very cold feed temps on the last flush is very good too. If you do not have them already, Get yourself a good PAR meter & thermal laser temp gun to monitor your plant top temperatures & optimize how much light your plants are getting. We are currently in the middle of producing a very comprehensive tutorial series for everybody to learn from & understand how to grow the highest level craft cannabis all on their own. If this interests you please check out our youtube and subscribe. The first 2 episodes are out the next one is coming in a few days. If you should ever have any questions or need any help, Please feel free to follow my profile and shoot me a DM. I will gladly help you with the pull down & make sure you get the best quality harvest possible as it is the most important step of the entire process.
Good luck my friend!
@LegacyMarketFarm,
Thanks for the info. just saw this today...will check out the links. Always learning. My soil Ph is 6.8, have been watering in at 6.0-64 to compensate. Not sure how to change the PH in soil. Had heat issues, and finally got that under control, but had some days in the 90s. Looks like I have passed up the stretch, and headed for some bulk. I changed the fans out as they were dying, so Now the plants are a bit stronger to hold up the buds.
