Hi, this is my first post.
Ive grown weed quite successfully in the past, keeping it simple, big pots, B and Q compost, no perlite, no clay pebbles, feeding when deficiencies manifest towards the end of the grow and putting them under one or two 600w HID in a 8x4 tent.
This time round I’ve changed things up quite a bit.
I’ve be bought an autopot system, I’ve bought 2 Zeus 600w pro, of which I am running one at the moment.
I’m growing in a room instead of a tent which is 7x10 foot, painted Matt white with white foam on the floor to absorb sound, reflect light and keep the water in the auto pots from getting cold, it is super bright in there with one Zeus on at 50%.
I have good air flow from outside ducted in 4” soil pipe.
I’m again using B and Q compost but mixed with a good bit of perlite with clay balls for drainage.
my temps are about 22C.
humidity is between 55-60.
it’s probably my most sophisticated set up to date.
Things was going ok, I was watering by hand till the roots hit the bottom of the pot, my super lemon haze seeds grew to about 18”, nice big broad leave, nice colour, then I turned on the auto pots for the first time.
They grew well for a few days, leaves praying, then they started to claw, thought they was over watered, maybe the lights was to close as I had them on at 100% at about 30cm away, then the leaves went dark green with lighter patches in between each vein.
I have 4 plants in normal pots so I watered them with just tap water and measured the run off, the PH was 6.6 but the ppm was 2400.
I thought maybe the soil was hot so I flushed all of them under the tap in the bath, maybe 30/40 litres, let them drain off in the bath, then measured the run off and it was around 500ppm.
Over the next few days I had them out of the auto pots and on drip trays, water was still draining so I measured it again and it jumped up to 1000ppm again so I flushed them all again and the run off is now a steady 550/600 ppm.
I stripped all the burnt and dark leaves off and trimmed the plants right back.
growth has been super slow, plants sensitive to light, leaves feel thin, light green with light patches between each vein.
my tap water has an EC of zero and is showing no PPM, I now suspect they have a calcium deficiency so I bought some magne-cal and have been folia feeding them 3ml in 1 litre a few times a day since yesterday’s they seem to have perked up and started growing again, they haven’t really grew for a few weeks.
the picture attached is how they look now, can you tell if it is a calcium deficiency?
Also I’ve since looked on the net at how much par the plants need at this stage and it’s around 400 par so that would mean the lights being 5ft away and on at 75% to give an even 400 par over 4ft square.
First time using LEDS so it been trial and error.
I thought this was my best set up ever but it’s fine nothing but disappoint and do my nut in!
so can anyone tell me if the picture looks like a calcium deficiency please.
sorry for being a long post wanker but I thought I’d give you all the info straight off the bat.
cheers.
