Decided to reintroduce some LST training on some top branches to level out the plant for better light penetration. I chose not to top this grow as I was worried about the harm it would cause the auto flowers, as I have not grown them before. However, I now know that the harm implemented through topping does not necessarily have a noticeable effect, even for auto flowers.
With the new budsites forming, I have begun to implement three additional nutrients, namely the REMO Bloom, AstroFlower and Natures Candy, following the regiment that was provided by 420 Fast Buds online, which has been highly influential in not burning my plants so far.
I was struggling with rising temperatures and lacking a proper lung room. However, I have since found that temperatures for LED grow setups such as mine can endure temperatures up to 85-87 before harm occurs, so my worry has dissipated significantly. I am not willing to invest in a proper AC unit precisely because of the price, and I would instead not choose a cheaper swamp cooler, for instance, so for the time being, I am just going with the flow.
Overall, the plant is stretching out quite a bit and will likely need a bit of defoliation within this week or next.
