My first Outdoor Grow- Deadhead OG

Along side my indoor grow i also picked up a couple of mother plants i decided to flower in my yard. grown from seed and supercropped already once, i bring you my Cali Connection's Deadhead OG soon to be harvested.

I picked them up as experiments, just to learn how to do my own outdoor grow since i already have a small indoor crop going. I learned how to deal with spider mites during veg and flower. Using horticultural mineral oil and a light pyrethrum/fatty acid mix between hosing during veg and soley pyrethrum/acid mix during flower.

The original owner fed his plants ONLY reverse osmosis water, and no nutrients but molasses. ...
...I feed them hosewater with distilled white vinegar to lower the ph, advanced nutrients bloom tea, big bud, and bud candy. I will post more pictures of better buds, but first i have some questions.

First up- About how long til i harvest? anyone?

Up Next- What is this? and how do i stop it, and should i just harvest those parts early, and how do i prevent it?

That is quite a cocktail from just molasses . So get a ec or ppm or tds meter cuz your heading for over or underfeeding . The plant with the burnt tips looks a little over fed so water with just calmag h20 that has been ph'ed check your runoff and try to keep the next feeding around 800ppm . I am not saying you can't go higher with big girls but I don't often. Oh and you got at least two more weeks from photos
Edit: I just looked closer but I am on my phone so take this for what you will but that burnt bud is a poss mold issue and may need to be cut out

well he cropped it before, i got it when it just had a few leaves and put it in new soil, its about 6'4" right now, in a trash can 2/3 full, so id say about 4 ft tall right now. How high do you go with your ppms with big girls vs small? my hose water is pretty hard, but up until now it was always lookin fine, always a smidge burnt, but never anything that would be alarming.

Can bud mold be cured, or is it too late for it?
