I have grown before but am having issues with some of the leaves on the plants. I dont gave a clear enough indication of what is going on. I am looking for some help.
I have all 4 plants DWC living together in a 15 gallon tote. I use floranova nurses with cal mag and flourilicious plus. I use RO water. I have 4 autos at 2 completely different stages.
I noticed these spots on the leaves anyone know what could be the cause?. I try to keep a close eye on the ph and like it around 6.2. I have 2 "450" watt LEDs and one 600 watt hps
Thanks everybody.20190214_073811.jpg 20190214_073748.jpg 20190214_073730.jpg 20190204_183154.jpg

I would run ph at 5.8 which will allow minor drift. Looking like the mag is not quite right.
I ran tap and had less issues instead of RO which I had to “ supplement “ . With about 200 ppm just to get right.

The LEDs are probably 12" away.

I'll keep the ph a little lower, to help the plants pick up nutrients that weren't as available at the 6.2 level. I'll increase the calmag as well.

Thanx

I would manage your pH a little closer to 5.8 as noted above...this will most likely correct your issues. If there's room in your feed, and you aren't already feeding your calmag at its recommended levels; I would bump this input up some. Good luck

how often are you changing your rez and i normally get this when my ph is too low as in 5.5 or lower
more air movement because that could also be moisture leaching out of the leaves and burning from the leds

I change the reservoir every 10 to 14 days at Max. I have really low humidity in the dry Saskatchewan winters, only about 20%. The leaves in question are really crispy.
I appreciate all the help from you guys, thanx

hang a towel, let one end sit in a pail of water.it will wick up water that u can put a fan on.should increase humidity.

i change every week regardless but i dont use RO so might be a waste to change that weekly depending oh how easily you can produce it. the reason i change mine every week is because i was told plants will use what nutrients it wants and will leave the rest in the rez and by topping up too much it will prevent the plant from taking up what it wants it also help keep everything clean and keeps the roots happy. have you checked your roots. are they happy and white and clean smelling
