Transplanted this week, 2 weeks from sprouts.
Soaked cubes 30 min in 5.5ph water with some nutrients ~550ppm
Added floraflex caps right away to avoid algae build up on cubes
2 center plants started drooping a bit half way through the week. I think it may have been from the rootball drying out and needing water since I just transplanted last week. I gave it a little bit of water around the root ball and it seemed to have responded well.
Plants started getting real bushy a couple of days after topping.
Low Stress Trained all the plants at the end of the week by tying them down using rubber coated garden wire to spread out the newly grown tops.
Also spaced out each plant evenly on the tray and turned on the other 2 PB2000 LED lights I had ready to go.
Added yellow sticky fly traps to all cubes as a preventative measure to avoid infestation of fungus gnats. So far none have been spotted.
Defoliated and did a little more LST to all the plants to open up the center and give more light to lower shoots.
Blue Dream 3 and Chemdawg 3 started showing some discoloration on the leaves (yellowing around the veins) and also the leaf tips curling down.
Did some research and came up with this...
Possible diagnosis:
- Yellowing around leaf veins could be a sign of Magnesium or Iron deficiency
- Leaf tip curling down could be a sign of Nitrogen Toxicity.
- Both could be caused by improper ph balance in water
Possible solutions:
- Applied Botanicare CalMag+ as a foliar feed and added some to the reservoir. CalMag+ contains Calcium, Magnesium and Iron.
- Diluted nutrients in reservoir to lower amount of nitrogen being fed to plants. Was feeding them at 1300ppm, lowered it to 1050ppm
- Tested runoff and saw it was coming out at 5.4pH so I increased the pH in the reservoir to 6.0. Now the runnoff is testing at 5.7pH, meaning that my rootzone is in the optimal range of 5.5-5.8
Well wait and see how the plants react to these slight tweaks. Hopefully we start to see a nice healthy even green again.
Set up Scrog in the start of the week.
Foliar fed with CalMag + Iron 3 times this week.
Defoliated lower shoots and fan leaves mid week.
Raised ph in reservoir to 6.1 because the runoff was coming out at 5.2 ph. Now the runoff is at a steady 5.6 ph.
Flipped to Flower this week.
First day of 12-12 light cycle was 10/04/21
Did some defoliating half way though the week.
Kept tucking taller shoots under the scrog net.
Also installed a dehumidifier near the end of the week becuase I couldn't get the humidity to go below 65%.
Flowers started showing up this week.
Flowers forming on nodes.
Did a flush this week for 3 days straight with RO water and CalMag+ to 250ppm and 5.8PH.
Middle 2 plants stretched a lot week 3 of flower. They were growing slower in veg so I flipped to flower as soon as their canopy reached the net (barely LST these 2 plants with the net given their slower growth). Then week 2-3 of flower they took off.
Did some defoliating to expose bud sites further down with the intent to increase yeilds.
Set up a second trellis net to help support the fatter tops that have gone far beyond the first trellis.
Added a second 6 inch clip fan to help with air flow.
One side of the tent had higher humidity but now with more air flow its solved the issue.
Blue Dream 1 started showing lots of rust spots and yellowing on leaves so I added more CalMag+ Iron to the reservoir believing the symptoms to be a deficiency in CalMag.
Blue Dream 3 also still showing signs of CalMag deficiency.

Nice looking tent man. Just a helpful word of advice, When we are dealing with the flowering stage of cannabis temperature can play a big role in terms of how your buds develop. By this I mean through lots of trial and error we have discovered when the tops of the plants are getting temperatures in excess of 82 degrees they will form big monster buds. The only issue is they will be very airy and prone to fox tail. The first 4 to 6 weeks depending on strain of the bud production is the development of the buds themselves. At this stage I personally find it best to run the temps as close to 82 as possible to get some nice big formations. Then as your plants begin to switch from bud formation to filling the buds themselves out slowly dropping the temps down to 77 with lights on and your nighttime temps at least 10 degrees less, they will dense up really hard and you will get the best of both worlds. Crops grown in flower the hole way through in the mid to high 70's will have great looking dense buds but the size can suffer ever so slightly. Keep up the good work man! Also this method will help increase the amount of cake your colas are producing. Post week 4 of flower more than 10 degree temperature variations between day and night will instead of causing your plants to stretch as they would in early flower or in veg, The energy will instead go to signaling the plants to cake up and produce more resin to make as much pollen as possible stick to the buds themselves for reproduction. It is taking advantage of the ability to signal the plant to do what it genetically wants to do to reproduce as much as possible and that is get sticky! sending the plants signals that make it think its life cycle is nearing the end and to do what its gotta do to reproduce. Whether that be make big buds to produce more seed, making more resin to attract more pollen to stick to the buds,etc. All of this can be triggered with Low-stress training and the less stress your plants receive prior to beginning LST, The more responsive they will be to it. You want them like spoiled supermodels up until the moment of LST begins lol. Sorry for the length of this post! I can talk cannabis all day.
