Quick Critical Plus

Early in week 7 i noticed bloody fungus gnats!! little buggers were hiding in some house plants and found their way onto my plant. they hit hard and the effects were instantly seen on my plants (i forgot to take photos). I believe the larvae caused considerable root damage as i was late to diagnose this issue. Anyway i went straight down to the local and got myself some liquid oxygen, the hydrogen peroxide kills the larvae on contact. the solution was 12% meaning a ratio of 1:16 is needed to kill fungus gnats. Smaller amounts can be added to hydro or soil when watering to increase the oxygen availability to the roots. This stuff worked straight away and with a little help from a folair pesticide i rid my grown room of all gnats. I am interested to see the effects a 1:16 ratio of liquid oxygen has on the bacteria and biotic life within the soil. i am concerned that the culture which has been built up within the soil had been destroyed. Because of this i have decided to stop using mammoth P at the end of this week. I plan to carry on using liquid oxygen throughout the remainder of the grow. Day 47. growth was slower due to the gnats. whilst i tied over each cola i noticed some issues on the leaves, after researching it looked like a phosphorous deficiency. I headed back to the local to grab a pH test kit. I tested the pH 3 times and found the average. Control water (bottled water with balanced pH)- 7.2 Tap water- 8.2 Runnoff from soil- 8.5 The result show that the pH of both the tap water and the runoff is considerably more alkali than it should be. From this i concluded that, due to the pH, my plant was suffering from Phosphorous def due to lockout. Furthermore, it is highly possible a build up of salts and other material has occurred due to a lack of flushes. To tackle this issue, i first flushed with pH neutral water. The next day i sprinkled ground coffee around the base of my plant to increase the acidity of the soil, i added a little water to help the grounds permeate through the soil. On the third day i mixed 1/4 dosage of veg fertilizer, 1/4 bloom fertilizer (increased phosphorous) with 2L of water and fed my plants. I tested the pH of the runoff again. the results were pH 7.2. I aim to lower the pH to between 6.2-6.7.
