Pineapple Auto- (first ever grow)

After finally starting to PH my water two weeks ago they are both having great reactions (go figure). Have PH'ing to around 6.5 each time and also realized the instructions for feeding on the fox farm big bloom was different on the bottle vs the table I got on the website, so I upped that to 2 tbsp instead of 1.5 (doseage halfed from their amount). Also held off on Calmag to only one feeding for the week with Vivosun plant. Vivosun- The white pistils are mostly turned amber and are now wrapping around the bud. I am keeping an eye on the trichomes, but still having a hard time getting good views of them using the magnifier and loupe I have (just need to figure out my technique). I am planning on this to be about a 15 week grow just based on nothing but other diaries I have seen, but have no idea and want to make sure I can get atleast a week to flush it. I am thinking I should do that once the sugar leaves show some amber trichomes, but then again this is my first grow so I have no idea lol. Leave coloring has greatly improved with PH water and increased bloom (it is a shame it took me that long to start it) Bestva- Buds are growing and pistils are slowly turning Amber. This one may have a week or two past the other plant, but it is making progress again after a week of nothing. Who knows, maybe it will just explode/or not. I only ever gave this Cal Mag once a week at half dose, but I stopped giving it to this plant as it was showing signs of nitro toxicity with it. It wasn't showing any deficiencies earlier, but wanted to be careful with the issues of my other plant. Figured less is more and don't give it anything it doesn't need. Wish I would have defoliated a little more in veg, but you live and learn. Still rotating pots every day under light to try to keep distribution of light as even as possible. Smell is getting stronger and stronger.
