What kind of problem is this? Calcium or manganese defficiency?
This is industrial perlite of a small fraction (couldn't find agro perlite in my place), when I water plants the top layer floats on the water and then setlles evenly on soil surface.Quote:

Since it's only on a couple of leaves, it looks to me like nute splashes or foliar feeding drops that have burned the leaf tissue. Possible heat stress, but on only one leaf..? If you foliar feed, do you spray just before lights-out, or raise the lights a bit to prevent burn?Quote:

During flower you'll want to keep humidity lower than usual. Bud rot and mold can appear if too humid.Quote:

Thanks for responding. I think you are right about fert splashes : )
Before installing humidifier my humidity was just about 10-20 now the humidity is at 40.
I water plants once a day in the morning, using tap water (starting use filtered water tomorrow) and greenworld 4.5-4.5-6 hydro fertiliser . How do you think I can improve my growing?
Hi cture...patience and an inate curiosity tword perfecting the craft can help you grow like the pros. (did I really say that..?)Quote:

40% relative humidity shouldn't be a problem, but my ladies love growing during the summer. Humidity here sometimes reaches up to the low teens. :jointsmile:
Anything else...? Oh yeah...would check into quality nutes and micros. There's bunches of em, and it's not real necessary to spend the rent money, but quality counts. Some two and three part regimins can get quite expensive, but getting the proper nutes for veg, and flower is going to pay off in no time. (greenworld hydro fert?)
HTH...Rusty
Here are the specs of the hydroponic fertiliser from ASB Greenworld I use.
N-4.5% (2.4%-nitrate, 2.1 - ammonia)
P2O5-4.5%
K2O-6%
B-0.01%
Cu-0.009%
Fe-0.034%
Mn-0.018%
Mo-0.001%
Zn-0.018%
At the moment concentration of this fert in the water 4ml/1litre
Here are some problems I have came up with today
on this picture I'm pretty shure about Calcium deffinsy

But this stuff on the bud leaf makes me confused What could it be?http://keep4u.ru/imgs/s/080124/4c/4c...fc8b21fb1a.jpg
Here are some problems I have came up with today
on 1ые picture I'm pretty shure about Calcium deficiency
But 2nd picture makes me confused What could it be?
