First grow ever: micro Hindu Kush Auto

Buds are developing slowly but surely. The plant started the week by stretching another 10cm in only a few days but stopped growing in height a few days ago. Luckily for me cause it was getting difficult to move the light up! Still have problem managing the RH through the week even if I did get lower humidity more often. I added some Green sensation by Plagron into the feeding at the end of the week. I was planning to stay full organic but the small phosphorus deficiency from last week got me worried so I decided to upgrade my nutes. Overall, even if the plant seems pretty healthy, she doesn't seem to thrive as much as before: upper leaves are staying palish green in comparaison with older leaves. They also stay pretty thin when I was used to see some large fingered ones. Stems are strong, buds are developing so I'm not panicking but I guess it deserve some special attention... No frost yet, which seems to be late of a few days if I compare with other growers with the same one. My thinking is that the defoliation might have stunt it a little bit last week (or it's just a slower one), but I'm not worried about that. Even if she becomes really needy and demands a lot of attention, the grow seems to go well so far.
