Big Bazooka so far has been a quick sprouting plant, some strains take longer than others however very few come up so nicely. If a plant doesn't grow all too well, I will usually leave it in a solo cup longer in hopes that the root structure will develop better. If for some reason things go really bad where the top of the plant looks like it might cause it to bend over on itself, a clothes pin or some other object should be used to help prop it up and support it for a week or so. Sometimes I use clothes pins when plants develop a twist at their base and want to topple over, clothes pins can help by putting tension on the plant and help them correct themselves.
To transplant, take the new vessel and place enough soil at the base so that the height of the old one will be where the top soil line will be where the new top soil line will be for the new one. Take the plant and the old vessel and flip it upside down and gingerly work it out through shaking, avoid tugging, and if need be squish the base of the solo cup until the contents are loosened. Then place the plant into the new vessel, now is the time to center the plant in the middle. Then fill in the sides with new soil and leave extra soil over the old soil line as a way to account for future settling. With fabric pots sometimes, sometimes pinching the base may be required to free roots that may have been stuck on the old fabric pot.
During transplanting certain strains may be stressed out, signs are usually lower (often oldest) fan leaves start to die off or top leafs change to a lighter color. Usually if plants are planted in fresh soil with lots of nutrients and water PH'd correctly, within a week the stress should pass. Usually the younger the plant the less likely the stress will be and Autoflowering plants shouldn't ever be transplanted as stress can be detrimental in the long run. If transplanting to larger fabric pots, I'll usually line it with top soil to help retain moisture and to prevent seepage from underneath or at least slow it down. One thing I would try in my future grows is adding mold to add to the root bundle as I hear it may prevent stress and benefit plant and soil health.
Transplanting is an easy and should be taken advantaged of by folks who are new to growing. I usually am quite vigilante and like to observe my plants, usually sitting and staring at plants for a good 10 minutes a day is quite tranquil but has the added advantage of spotting issues. If watering is done correctly then most issues can be corrected by transplanting, my first grow hadn't had PH'd water until fairly late in the grow. A good way to gauge is when a container gets too small the bottom node leafs will change yellow. A good passage of transplanting through it's life is solo cup to 2 gallon pot, to 3 gallon pot, to 5 gallon pot, to 7 gallon pot, to 10 gallon pot. Once experience and skills are gained going the route some sizes can be removed, if a strain is too sensitive to transplanting it may take longer to grow but it will allow a safer route. Usually transplanting to something double the volume is best.
After transplanting I usually will wet down the very top soil as it will usually be too dry and allow water to penetrate too deep too fast. Then slowly keep adding water in the evening. My watering habits are that I check my plants first thing in the morning and the first thing when I get home from work.
This weed is strong
I have some really crazy brain vibrations
Kicking in very hard
Defiantly a very strong strain
