Oct. 10 - Day 93 from seed - beginning of week 6 of flowering. We take a closer look at those leaves - they looked suffering - and we notice small black dots. Not sure what it is - mites or other fuckers like that - we decide to take immediate action: the same day we shower the plants with soft potassium soap and water and then with a mix of water/soft potassium soap for Bio agriculture/SMC Spider Mite Control trying to avoid flowers (almost impossible). We do this treatment immediately before the lights in the box go off for the night. In the morning we flush the reservoir, flush it with water for few hours and then we do a new solution (Hesi hydro week 6 diet) to put in the reservoir.
