[FONT=Arial, Helvetica, sans-serif]hello fellows,
im testing my first coco grow and im a bit confused and worried because some of my plants seems not to be very happy.
i have read a lot of threads and advices about how to feed in coco but im still confused.
the plants are 30 to 40 cm tall and are from seeds in 4 liters pots hand watered, 600w hps lamp per square meter. i fed them at ec 1.8/1.9 because two or three weeks ago they were underfed and began to yellow. usually i fertilize with a runoff but since two weeks no runoff. i use the canna coco nutrients line and i always adjust the ph at 5.5/5.8. now the tallest plants have very dark green folliage maybe a bit overfed too but the smallest plants who are under the bulbs are yellowing and some medium plants too.
i read that when checking the ec of the runoff, its acceptable to have an ec 0.3 higher than the ec you fed.
today without checking the ec of the runoff i panicked and began to rince some plants with a mild fertilizer solution with an ec of 1.0
when i rinced a little with the solution of ec 1.0 some of the tallest dark green plants had an EC range of 1.8/2.2/2.4 in the runoff and some of the smallest plants who are a bit yellow had a ec range of 1.6/1.8 in the run off. i rinced 25 plants or so until the runoff was 1.4/1.6 ec. the ph in the runoff was always good 5.5/5.8.
now im wondering if i was right to do that and i still have 80 plants to rince tomorow but i need help to know if im right to do that.
help me please !
