Good morning
I've overfed Charlotte and her leaves have gone a very dark green. Having googled, I've concluded that I've fed her too much Miracle Grow or tomato feed and has nitrogen poisoning. She lives in my greenhouse and is either an Auto #1 or an AK Advanced Female (got my seeds muddled up, so not sure which. Both dwarf varieties)
Charlotte has been flowering for a number of weeks (due to lockdown I've lost track of time so can't say exactly how long - around 3 weeks possibly) but her hairs, although changing from white to orange, are still predominantly white.
My question is. Should I harvest her now (because of nitrogen issue) or wait and give her plenty of plain water (flush?)
Many thanks.

Nitrogen is quite mobile - so ya. Flush and give it some time to work out the excess. You don't want N to be the highest note in that music.

If you are gonna harvest - finish with regular (ph corrected to 6.1-6.3) water. I'd suggest to not use RO water, as that creates other problems.
edit-
Photos just dropped. Those don't look bad. A little toasty on the ends and more time for flower looks to be where you are. Those flowers can get alot bigger if you are gonna be nice and patient.

your case of n-toxicity doesn't look too bad....correct its watering/feeding, and these plants should recover quickly, check new growth for any more n-toxicity.....i've had worse bouts.

keep going, no need to pull up stumps, full course.

This may be that one special time where the feed goes to a potassium-phosphorus (PK) kick. Nitrogen is expressly excluded.

The recipe changes just once, for a week or so. This may be why there is a sense of pouting from your plant.

Miricle grow is not suitable for growing weed, not only do they put food in the mix so everytime you water you feed, but they put sodium in the mix ( salt ) buy a mix made for weed, most people who buy there mix use fox farms, pro mix, or in the UK bio bizz, i recommend fox farms ocean forest.

Very expensive though! What money I save growing my own, will disappear on plant food.

Once you see clawing and a waxy look on the edge of leafs that's when n toxicity is getting bad. Plants overall look good. Also on money I think ff trio is $45ish. That's like 2 3 days of buying bud lol.

This^^^ It's not a nitrogen tox here. IMO its the very beginning of K deficiency

Awesome info, looking more into this. Possibly why I noticed minor n tox recently on 2 plants that are younger.

How many plants do you have? I use age old nutrients and botanicare calmag. Total is $60 per 36 plants from clone to harvest and worth every penny.
