Hi all I'm desperate for help off you guys. My plants aren't looking to healthy and I don't no why. The leaves are drying out and yellowing with some brown spots. Temp is 29.c humidity is 40% nutes are all the canna range I've been feeding them with 13ml per 10liters of a+b 12ml per 10liters of zym and 10ml per 10 litres of rhizotonic. They didn't show any signs of this last night and Ive looked 24hrs later and bang they look terrible. I haven't watered for 5days as the soil has remained moist but decided to give them a feed earlier to see if that perks them up a bit. They are in there 5th week of life and I'm worried they will die. Here are some pics. Ph is between 5.8 and 6.1. The problem is with the lower fan leaves on some but others are just showing on the top fan leaves. Thanks guys.
