Purple Punch Autos

Don't top autos. Just lst them aggressively. I would start now even. It will greatly increase your yield without the stress of topping.

check out a VPD chart that shows suggest ranges for various stages of life cycle. RH % is a little high. >65 puts you in territory that grows microbes too effciently. raises risks, but with 80-84F, the VPD is looks good when lights are on. not sure what it significantly impacts in dark cycle... Defintely don't want RH going higher. Preferably drop a bit and if so temps scaled down slightly too. A little higher VPD than rpesently is fine, if not.

No, 78F is just fine... your humidity is on the high end of being ok so do watch that... The biggest thing I would caution you about is the amount of Grow Big you're giving her.... I've used FoxFarm in my soil grows and have always needed to cut that down as soon into flower as possible.... You run the risk of developing a nitrogen toxicity and a lockout if you don't. Overall, though, you're doing a magnificent job! Congratulations and good luck the rest of the way!

If its only on the top leaves that could be it, but I feel it something else. To me its looking like it may want some magnesium and I see the beginning of spotting that might be from calcium deficiency. A lot of the products your using from fox farms feed really heavy if followed by there suggested feeding guide, lots of PK and some N covering the NPK macros but I don't see the micros content on them labels. Want to ensure its getting enough Magnesium and Calcium. If it needs a boost a supplement should be added as long as its within the range of EC you want to feed the plant. I don't see that your monitoring the EC in the diary but might be something you would be interested in doing in the near future. Can help avoid issues in the long term with feeding and concentrations. Best Of Luck!

The best way to feed autos with liquid nutrients I find is like this: Mix up lets say 1Gal of feed with the ratios they are suggesting cut in half, so as a simple example,[ 1ml/l : 3ml/l : 2ml/l ] of [ grow : bloom : micro ], I don't think fox farm has micro but you get the point, keep the ratios the same between the different nutrients your using then just add more water to dilute it down to the EC range your looking for, after that PH adjust the solution from there. If your using CaMg it will use up almost half of your allocated EC budget as its so high in conductivity. Eg if your aiming for a EC of 1.0 do not be surprised if when adding CaMg it jumps from 0 to 0.4 This web page is a solid reference point for auto feedings. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ Its not 100% and something may need a small adjustment but its good frame work to build off of. I'm a little rusty on the order of adding but I think it goes silicon "if useing it" + stir really well and let it chill, then CaMg + stir, Then the rest. Last part is PH adjust. Best Of Luck!

I’d say take it down now to a week max. You got a weird pheno kinda as far as it being hard to tell leaf from bract/calyx But what’s important to look at is mainly the bracts/calyxes not so much sugar leaves. Now trichs can become ambered and degraded from physical touch or other factors aside from natural maturation. I try to open up the bud a bit to peak into areas that haven’t been touched by me or anything else thru it’s life cycle. Your trich shots look pretty prime depending on what effects you’re hoping for. As far as where on the plant - something getting direct light is where I look. Usually I will take a look at an upper bud and then somewhere in the middle and mentally come up with an average of where things stand given the conditions of both areas.

whether convenience is enough is personal preference. if you're looking for reassurance it's not a huge opportunity cost or something, it's pretty close. it looks a tad early, tho. the amber i see seems to be on the leaves but guessing a bit in pictures too. the triches look more like plastic than glass, so that's a good sign. how is density? (rhetorical). the pistils all have colors but a bit long yet, which could mean some more plump is possible. it wouldn't be the worst weed and possibly couldn't tell difference as far as buzz. primary cost would be loss of yield, i'd guess. go with convenience or let it ride another 7-10 days?... use a smaller light if possible to match 1 plant and reduce watts.
