G13 Haze balcony grow

Week starting 4/10/2019 Spotted a few aphids today on some of the yellowing leaves - confirmed with the magnifying glass. Humidity continues to be an issue as I cannot seem to lower it below 60% at best, averaging 65%. The extraction currently is pulling the air from the tent into the room - will need to look into taking it outside of the house before looking at dehumidifiers. White powdery mildew is more prevalent on some of the tops. Manually wiping them off with a wet cloth each day. 05/10 - Applied nematodes today to all 4 pots (https://www.biogroei.fr/stenema). Had to apply it with water at pH6.5 08/10 - Watered all 4 plants to keep the soil moist for the nematodes. #1 08/10 - Watered at pH6.3 at 17 deg 10/10 - Feed of Vega at pH6.4 at 19.8 deg, EC 1.84 - still seems stunted during flowering and behind the others of same strain by a week or two. #2 08/10 - Watered at pH6.3 at 17 deg 10/10 - Feed of Vega at pH6.4 at 19.8 deg, EC 1.84 (pot was not dry yet, should have waited another day or two with feeding) - colas are still developing nicely whilst continuing with the leaf loss. - defoliated and cut all small branches with flowers at the bottom. #3 08/10 - Watered at pH6.3 at 17 deg 10/10 - Feed of Vega at pH6.4 at 19.8 deg, EC 1.84 (pot was not dry yet, should have waited another day or two with feeding) - a few curled/twisted leaves. Continues to need the most frequent watering - most probably due to the limited 7L pot. #4 08/10 - Watered at pH6.3 at 17 deg - is not drinking a lot of water compared to the other 3 G13 Haze strains. - getting close to harvest time, still not showing big signs of nutrient deficiencies or other issues. Some purple leaves at the very top of the main cola.
