new to auto flowers

found one leaf like this

now that looks like cal/ mag def. I think. At day 25 it could very well be that now they need more.
you did say led and sun right ?
happens a lot with led's, don't know why.
I use botanicare cal mag with my led's.
Also you could try a little fan blowing up gently thru the plants.
That could be it, worth a shot a this point.
 
Yeah i looked at the water source coming into my house

as this is my water

http://www.calgary.ca/UEP/Water/Pag...-quality-report/Water-Quality-Parameters.aspx

I use hot water to dissolve the dry nutes then fill with warm. all hot water comes from water softener! I thought the kitchen sink was from a bypass i was wrong .

going to use irrigation system bypass to mix up fresh nutes and flush????? mix hard water nutes and foliar spray ????

water has 165 ppm CaCO3 (gypsum/calcium carbonate) thats our water hardness 11.6 grains/ gallon . plenty so should not show cal def right????

plan of action is this reversible ? a lock out?

Ok good luck.it might just be me but hempy seems to take longer to level out.
Dont know if epson helps with calcium or magnesium. One or the other i think.
Dont know about warm water either
I know in my dwc 68° is perfect.
They are extremely resilent plants.
 
Yeah I think the salt in the water softener strips the calcium out not going to look till tonight . I will check for further rusting on leafs .

epsom is magnesium, but the new growth showed purpling veins as well as the rusting on the leaf you saw in photo

Hot water is needed to dissolve the maxibloom dry nutes so I will microwave a jar of water from my irrigation line for mixing fertilizers.

yeah cooler res = no root fungus (Y)
 
ha,here you go, this is my hempy that I messed up big time as seedling,worst grow ever.

I have seen 3 gallon hempy buckets pull a pound a plant indoor/outdoor summer grow so it works. like any grow its in the details and keeping things smooth low stress ... lol I fucked the stress part but we will see if it sucks I will pollinate em with some dp ww auto pollen (a friend has plenty). If they die i have a few others going in soilless smart pots.
