Hey all, I have had yellowing leaves and a handful of burnt leaves in a few of my plants. I put 30ml of flora nova grow in my 40 gallon res. the ppm read 400 the first day at week one. every day after it was at 1000-1100ppm. the plants started yellowing a bit and 5 started burning, but many of them seemed fine.
on sunday was the end of week 2, I changed out my reservoirs for 80 gallon tanks. and flushed the tables for a day with just water. my friend(owner of the house) got caught up and i couldnt go add nutes to the res for 2 days. so the plants were on water alone for 3 days. when i got there today, the plants ALL have yellowing. a lot, actually. and maybe 15 of them have burnt and crispy leaves. Im assuming its from not having nutes? I added 15ml per 80 gallons of flora nova grow, the meter read 400ppm and it held steady all day after flooding the table a few times. I will work up higher if they want more.
quick rundown of my setup.
Mandala seeds Satori strain 3 weeks old
4 tables 4x5ft each w/ 20 plants in 3 gallon buckets.
4 HPS 1000watt lamps, with DIY air cooled hoods. 18/6
Hydroton
Flora nova grow, bloom.
Temps are average of 80-83 light on. 77 lights off.
Just installed a 19,000 btu Split system A/C and will drop temps tomorrow.
here are some pics i took of the yellow plants, some burnt and one that is growing one sided. sorry for the bad quality the HPS lights really throw off my camera.
the lighting makes them look orangy but they are yellow. and some have burnt up. I have replacements in a cloning chamber that were left over from the 100 i grew so i can replace the damaged ones if they dont recover.
