Hi and thanks for the pictures!
First of all nice work, mainlining is always a really cool technique and a lot of fun to do. You can clearly see the structure coming along, so youâre definitely on the right track.
About your question: itâs completely normal that different strains show pistils at slightly different times. Even within the same environment, genetics play a huge role. Some plants are just quicker to show sex, others take a bit longer nothing to worry about at all, especially at day 28.
What I do always recommend: keep your humidity in check during veg and aim to keep it on the higher side. That really helps with growth and recovery, especially when doing training like this.
Also, Iâd suggest hanging your light a bit higher and increasing intensity rather than having it too close to the plants. LEDs can stress plants more than people expect when theyâre too close.
As for nutrients and support, I personally stick to a few âgo-toâ products:
Boom Boom Spray from BioTabs : honestly amazing stuff, plants absolutely love it
Root stimulator from Atami Bâcuzz: in my opinion one of the best on the market
Epsom salt (for magnesium support)
Overall, youâre doing well just give them a bit more time and keep the environment dialed in.
And the rest is just Love
Good luck and enjoy the process đ±đ
