Day 50 since seed touched soil. They overgrew everything !!! Devil is HUGE and strong and hungry ;)))) . I think i was late with top up, they developed fast and used a lot. I check run off for ppm, but thought 800 still ok, it was not. So big last top up !!! plus to call it measuring would be sin, i collect all run off, mixed from all 3 plants, but its still gives small feel. ALL NUTRITIONS ARE GRAMS TO POT LITRES !!!! Neutralise is in real measurement only. Great White - 3 g each pot Biosys - 3g each pot Charge - 30 g each pot Life-Cycle - 60 g each pot Bio-Blend - 100 g each pot Watered straight after, 4 liters went in. Some girls are almost brushing Mars Hydro TSL2000 and i see no issues if air is moved and temp with humidity allows it. Great light, plants grow very well, too well ;)))) will do new clearing after two waterings, want girls to eat first, make bigger roots, then i will resize again to concentrate more on tops. MARS HYDRO TSL2000: 300W, Flower 2'x4', Veg 3'x5' It's recommended for beginners. Low-budget & high-efficiency. Took down first time ever LST while still growing. Needed space of pot, for last top up and i think they will breath better without, branches are stiff, i would add silica to feed at such time, to stiff them, but i go with one line only, just full beans ;))) Happy growing !!!
