Running 400W HPS in 1mx1mx2m tent in central Vic. It's exactly 21 days since I flipped to 12/12 and all of a sudden with the increase in outdoor daytime temps I'm seeing temps in the tent soar to 33 degrees at the end of lights out. I've currently got the lights on from 5am to 5 pm but am thinking it would be better to run them from about 8pm to 8am during the night instead. Would changing over stress the plants? Best to doing a one off night period of 27 hours and then move to new schedule? Any advice welcome. Cheers

Stacked OG Kush in soil and 20% perlite. Using Montys Organic Fertiliser and Wise Wallys Superfeed [worm fertiliser]. She is showing leaves curling downwards and tip burns. Leaf curling seems to be confined towards the bottom of the plant. 2 other plants, Grapefruit and Skunk #1 showing none of these problems. I flushed yesterday with about 5L water because I assumed it was nute burn, now I'm wondering if it's not overwatered in which case I've probably exacerbated the problem! Photos aren't great cause its bloody windy here today. Any advice welcome.

These 2 plants were about 12 inches away from the bottom part of a large reflector w/600W MH. The heat coming off the inner sides of the reflector under which the plants were sitting is fairly intense, I'd say hot enough to dry out a piece of bread in a couple of minute but not hot enough to start turning it brown. The affected leaves feel quite brittle, but I can still bend them without breaking them apart. Ambient temps are around 25.5 - 27.5, humidity is around 30%. I also fed these plants a couple of days ago, so there is the possiblity its nut burn or maybe even pH flux as the pH was a tad lower than usual. Thanks.

Hey Im trying to find a way to take preventative measures in protecting my plants from mold. Now ive read up on what to do when you have mold and the need for airflow etc. But im more talking about sestemic sprays with short holding periods to use 2-3 weeks into flower when they are just starting to bud up. I have an indica dominant that i grow in my tent, i keep things clean as i can with good airflow but i still suffer from mold every time at about week 8 if im lucky and not earlyer. Does anyone have a recommendation? Thanx in advance

I only noticed this the other day. The branch nodes have this weird looking....I don't know what you would call it......Looks like she has been lifting weights. This is only apparent on the Red Devil F4 both pheno's. The photo variety of the same generation doesn't have it, well it does but it's hardly noticeable. Anyone else had this happen before?

Hey guys, I've been lurking the forums for close to 7 years now, reading grow diaries and gathering every bit of info possible about growing your own, green with envy. Finally, this year I began the noble journey with a nice white widow / big bud girl. I've made beginner mistakes left right and centre but all in all I'm happy with the progress with no major fuck ups.... however... She's on her 6th week in flower, after tying her up the other day I noticed seed sites on the stems on one side of the plant. They're rather small and after some investigation I've theorised that light leakage into my cheapie tent is the likely cause of this development. I checked the buds and…
