first grow, first nutrient feeding help
so im doing my first grow in coco about 50/50 coco perlite and im wondering when i should start giving them nutrients? so far its been only ro water phd to 5.8-6.0.
i have regular, feminized and auto flowers (the autos are about 10 daays behind the others) all growing at once, from what ive gathered you shouldnt start nutrients for about 3 weeks or 3-5 nodes but my plants are growing like crap, very light light green leaves, very purple even on the veins of the leaves of some of the plants, which only have 2 sets of leaves on the most advanced.
one of the ones with only 1 set of leaves is showing some of the worst purpling, should i have been giving them light nutrient feedings sooner?
as of writing this ive giving two of the "runts" with heavy signs of purpling a light nutrient feeding of 150 ppm just to see what happens as i suspect growing in coco with no nutrients is the problem and i shoudl have been giving very light feedings the entire time, thank you for any repleis / input people can give
