Gdp1 has been flushed until runoff showed 100ppm. Gdp3 has also beem flushed with runoff at around 100ppm as well. Mostly all of both plants' trichs are cloudy so harvest is nearing for them. The other two Gdp 2 and Gdp4 still have a bit of time, they were both flushed with runoff running around 6.3-6.5pH and ppms between 500-700 respecitively for both plants. The pH was low at first and I believe thats why the leaves look like crap and maybe caused a lockout causing the buds to develop slowly. Besides the leaves being ugly, the buds look great which is the important part. Happy growing!
