Hi all first timer here
I’m growing 3 different autos (diesel, ak, blueberry) from seed in 160x 80x80 tent
soil grow 7L pots
in veg now, some lst done .
24hrs lighting
light CFL 150W + cheap led from eBay 45wats + self made full spectrum LED
300w ( not used atm as light bur suspected)
using sonoff self made sys to control and monitor lights, humidifier and heating.
temp 22-26 degrees C
humidity 40-70%
totaly messed up the feeding from the beginning .
then my control system sensor fault burned (49C)my two plants NL auto and jack auto
then ph issues ( I think I got this sorted)

Self made 300W

That’s the current state
flushed them 3 days ago RO water pH6 , runoff pH7
then fed npk mix 5ml/L which is half the dose also added sulphur power,
calmag+, seaweEd and molasses (feed runoff 600-800ppm)
new growth looks ok but older fan leaves look bad
im I on right track ? And if not how
to get there ?
im thinking to stop using RO water
for next feed and to pH to 6.5
and 300-500ppm mix



All comen and advice are welcome
and much appreciated
I was thinking about the light question he asked you, is there a reason you run 24 hrs? Imo I have come to think of plants as people in a strange kinda way and in so I like to give my girls some time to rest as well as that is when most root production takes place. Some peeps would argue for this reason or that, and thats cool, I was just curious?
Ok thanks for the info. Let's see how the plant reacts from the flush.
Your plants don't look that bad. The yellowing of the tips and edges is sometimes a sign of over-watering. Interesting looking grow light! It definitely sounds like you're on the right path. Questions for you:
-Are you in soil or coco?
-How often do you water? -Why do you run 24-hours of light?
-Why stop using RO water?
-What type of diodes are you using in that custom 300w? Thanks for asking questions on this forum. I'll continue to answer when needed! Cheers!
