no nutes for 3 days , quarter strength 3 days then ill see how they adjust i will also be applying c02 2hours morning and night boost up nute consumption.9 seedlings in a plastic 20 gallon storage tote . mylared inside all the way around. 1 ft by 2 ft . 150 hps .
put them in a new medium.. even larger cubes will help..
cheers
they have nute burn on the tips, i would also say the PH is way off, do you set it? read it? did ya soak the cubes in a 5.5 PH water b4 using them,
the thing is with hand watering rock wool is the longer it sita there the higher the ph and the more concentrated the nutes become due to the action of evapouration! i think an enzyme wash once a week at least to give them a chanc, lower and control your feeds and PH the sollutions to 5.5 until they come out about the same or 5.7, thats the water that drains out!
good liuck, ant get them in some arlita [hydroton] as soon as poss with an automated feeder,
welcome to the world of endless possibilities,,,,,hydroponics
when to harvest. also c02 on seedlings transplanted yesterday
I really dig your pictures!!
