Girls are looking very healthy overall. First time running just Coco and perlite so hopefully these girls won't run into any big nutrient issues. So far the sour stomper is flowering fast and is also the healthiest. The pink panama is still smallish but not as bad as before. Both the forum stompers are really getting big and slowly flowering so I expect another week of stretching.
strong start gromo - may i suggest you investigate predator bugs. these terminators will eat eggs, larvae etc so you hit the fukkas at source. i've tried a number of different methods - neem oil, diatomaceous earth, stickies etc. but since using the bugs i've not seen any evidence, on leaves or on stickies, of any presence. not sure where you based - i use a company called dragonfli. they have a solution to most if not all pest problems we erb growers encounter.
@mr_h_kovert, yea I might order some nematodes if the diatomaceous earth doesn't work but so far haven't had any more gnats pop up. Luckily my grow area is pretty sterile when it comes to pest. Last time I had gnats was last summer.
