Day 50 since seed touched soil. They overgrew everything !!! Cookie is nuts, so stacked, always happy, leaves are on healthy part, but could eat more ;))))) . 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 !!! 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, 3.5 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 !!!
