Gorilla Glue Auto

Last week of vegitation and I've definitely run into some issues this week - mostly as a result of overwatering in the first few. The plants are all showing some form of magnesium deficiency, the worst have very yellowing bottom leaves and dark purple stems, the best have just a few purple stems. I've given the soil 30ml of Dr Greenthumbs tonic (in 2l of rainwater), and used 60ml of Magnesium Chelate as a foliar spray (in 3l of rainwater) to try and get it under control. It doesn't appear to have caused too much of an issue yet as the plants have continued to grow well, so hopefully the additional magnesium will sort things out. The other problem is bugs. I'm guessing these are the result of the amount of water sitting in the bottom of tent over the first couple of weeks. I've since bought a wetdry vac and removed the water, but the bugs are still there. They look like winged ants. but also don't look like they're doing any harm... but I can't imagine they bring good news. I've purchased some organic bug remover and can hopefully get that issue under control before flowering starts.
