So Iām doing dual root system and everything was doing so well and looking very green up to about 2 weeks ago all my fan leafs started to get really pale and spot brown, Iām not sure why and i just Canāt figure out where my problem is.
If it were me, I would probably not worry too much about it...add some epsom salt dissolved in your water. Looks like your lava rock maybe isn't providing as much volcanic rock dust as your grow needs for cal mag. The foliage indicates possible calcium mag iron deficiency. Your plants grown with all naturally provided nutrients are looking nice.
