If your baby's are already on 12/12 even at the very beginning of flower AVOID ANY CHEMICALS use a product like liquid lady bug (or similar) to complete this flowering stage. You will need a few spray session to limit the damage to your plants, you can use liquid lady bug up to the very last day . 5 Days to a week into veg of your next use Floramite ( Hexygon & Forbid work too ) Do it even if you don't see any mites at this point & spray again a week later. The chemicals will have plenty of time diapered & the pest will be eradicated.
Home made Liquid lady bug : Use 1L of steam water add 4ml of Organic Peppermint Oil, 3ml Organic Geranium oil, 1ml citric acid and a drop of organic soap.
Alternate : Use 1L of steam water add 3ml Organic Lemongrass oil, 2ml Organic Geranium oil, 2ml Organic Garlic extract and a drop of organic soap.
Some Hydro-shop will sell Floramite in pre-mesure dose. It's way more affordable than the 300 $ a full bottle cost. I bought mine in 50ml bottle on ebay.
