Pics from day 56
At the end of week 7 I overfed lennon 3 and some leaves burned, she has been receiving only water since, and it seems that she is ok now.
Lennon 2 still has the biggest buds of the 3 plants, it think i'll give her 2 more weeks to go.
Regarding the slow flowering rate of the plants: do you think it's fine?? Should I pump up the nutes? (I feed them every 2 irrigations with the doses posted above).
No I wouldn't up the feed at this point. More food won't make it flower faster. Just let her go at her own pace and she will let you know when she is ready. Good luck!
