Big Yield Auto (first ever grow!)

Its hard to say. They could of been improperly stored by the breeder or you. During shipping they could of gotten to hot and died. Your paper towel looks a little to wet which could of drown the seeds( rare to happen ). When you planted your tools/hands could of had bad bacteria on them and killed the taproot. Or it could of broke when you planted it. The soil used could of had some fungus growth right where the seed popped and killed it( damping off) So many variables that could cause a seed to not germinate or die right away. 70% success rate means your doing something right and that is what matters Happy Growing and good luck

Peroxide can actually stimulate germination, but in my opinion good genetics germinate very well on their own without help

You should almost never defoliate. Leaves = energy. With the current size of your plant it would slow her down dramatically by removing leaves. Only reason you should is if your doing a SOG or SCROG and need more airflow below the canopy. Most of the time the plant will naturally defoliate any leaves that don't get enough light. If anything you want to focus the growth by removing the lower and inner "Sucker" growth. Each fan leaf will have new growth between the main stem and the leaf. This is what I call sucker growth. It will grow just like the main stem and is where buds will start growing when she matures. By removing the lower growth she will focus more on the upper growth and be less bushey. But remember each "Sucker" growth removed is a potential bud site and/or lateral growth. Your growing an auto flower, Your best bang for your buck is to do some LST. Bend the main stem back and forth between the leaf growth to weaken it. Then once its weakened carfully bend her over and steak her down. All of the "Sucker" growth will now have more light and start growing faster and larger. It will usually take less then a day for the plant to adjust and be bending towards the light again. Good Luck and Happy Growing

Each seed is going to produce it's own individual... they're going to vary in height, what they like to eat, how they grow... maybe not a LOT but there will be differences every time unless you're working with clones. That's part of the magic, part of the challenge... Your grow looks stunning and I wouldn't be complaining or worrying about a thing!

BioBizz nutrients do not do well below a PH of 6.2, giving your going in at 6 I would bump that up. Also not all nutrient brands are interchangeable, some of them might reacted with each other and lock out things in the medium. This to me looks like a calcium issue and I bet its caused by a lock out of to many fertilizers in the medium. Your going in a 1.4ec with a lot of products. Autos like to lightly feed compared to there photoperiod counterparts. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ This is a great reference point for auto feeding, it needs to be noted it is not universal but a great start. I would also look at monitoring your runoff EC if you are getting any. This will let you know how much the plants need. If the ec is higher in the run off its getting to much,. The EC and PH values will have a small effect on each other as well. lower ec raises PH and higher EC will lower the PH..typically.

You want to use this 4-10 days before you harvest so this is something you're going to have to decide. It's a nice window, actually - gives you a bit of flexibility as to when you harvest! Take a look at the trichs and figure out if they need another week or so or if you need to harvest quickly (4 days) ....then mix up a solution and thoroughly soak your pots. Then you wait 6 hours and flush the pots with clear, pH'd water and continue to ONLY give the plants pH'd water until you harvest... Sounds like you're approaching trim jail! COOL!!!! Good luck....
