Hello everyone, I'm new to this site so some patients would be very much appreciated i have done a few auto grows before but seem to run into the same problems 2nd week of bloom the first 4 weeks are perfect and couldn't look better but it seems every time starting from week 2 of bloom the leaves start looking bad. I'm not sure what it could be I'm thinking either cal mag? Or possibly damp leaves when lights off and possibly burning on lights on? I'll write a list of the grow.
5x5x5ft grow tent
200w 400w 600w sol digital variable ballast-
Bulbs: 600w metal halide-
600w hps dual spectrum-
Air cooled reflecter.
720m2 rvk 6" rhino filter on variable speed control running half speed.-
Small computer fan blowing air in from outside not sure how much possibly 120m2-
Fans blowing lightly over plants.
Soil: plant magic / 25% perlite mix-
Nutes: plant magic don't usually use many?
Ph: I always put water in at 6.5ph
Water ppm (tap water 250ppm always left to sit for 2 days.
Can start using RO if you think it's better?-
Daytime temp around 24-25°c-
Night temps 19.9°c-
Can't seem to get temps up or is this ok? Always liked 26°c usually.-
Humidity is always high first 4 weeks 80%
Humidity in bloom is around 60%-
I don't feed anything for the first 4 weeks just usually-
Pm root stimulant and bio silicon at around 5ml per litre.
Week 4-5 (first week of bloom when nuggets are 1p sized I add 0.5 of pm bloom but after this I always get the leaf problems so I just usually just water and every 2 or 3 feeds do 0.5ml of bloom as don't want to risk anymore damage. Just seems like the first second week of bloom things start going wrong. I really don't think it's nute as I know exactly what nute burn is as I've had this with previous grows. I water 6 plants around 10 litres once a week? I'm confident my temps are to low and the leaves could be getting wet on lights off then burning on lights on? Or possibly a slight nitrogen and or need some cal mag which I've just ordered.
I hope I've given enough information for people to help and I'll add pictures. Sorry it's my first time posting so hope it's ok.
Appreciate anyone's help. Many thanks-
