Hey guys, I got 2 plants growing and I have one that is ready to be flushed with water for 2 weeks before i harvest but I have another plant that may be a different strain that isnt ready yet. I am using an aeromachine so does anyone have a good idea on how i can flush the ready one with water without interupting the plant that needs a few more weeks? Would it matter to the other plant that it was getting just pure water for like a week and then put back on nuts? Does anyone else flush there plants before harvest?

Hello everyone, I have a bagseed plant growing in coco coir with about 20% perlite. I usually adjust my nutes to 5-6 PH (Can't exactly tell cause only have liquid PH tester that goes up 5, 5.5, 6) She (hopefully) is upto about the 6th node and a foot high and over the last few days the tips of the leaves were going brown and sort of curling up.... Looked around and can't seem to find what it means... It isn't heat stress cause its over the entire plant. I flushed her (please be a her) ph 5.5 water then today I gave her almost full strength DutchMaster Hot CoCo with a bit of superthrive and also FIMed her (Pleaseeeeeeeeeee). The tips are still looking the same tho...…

Can someone with experience tell me if it is worth trying? Is the benefit a shorter cycle, or bigger yield? Can you estimate this as a percentage increase? thanks.

hello guys, to be honest i'm quite shocked to discover do many coneissuers,.. and i thought i was a junkie... . anyway, ages ago my mate found a seed in some bud and decided to grow it, can't remember what the gear was like, don't even know if it was hydro or bush, in fact i'm very intrigued to hear about all the different vareties out there, and i thought they were only things found in europe amsterdam etc. he germinated the seed in january 26 (australia day or some public holiday) so he's had it for half a year and it's nowhere near flowering... i know the growing conditions aren't right but... it's in a 30cmx45cmx120cm box, yes it's tiny... and he has 2 compact…

Hey ppl Ok I finally got some baby seedlings growing, just chucked one seed per plasic cup filled with potting mix and waited. 7 out of 12 have sprouted since last friday, latest one popped its head out today Almost cooked the poor things when I put them outside in 'full sun' - they were only out for about 6 hrs but they were so nearly dead! At least one doesnt look like it will make it. I was so excited to see the first signs of life from those dull looking seeds Anyway, 2 of them have come up with the seed open at the top of the stem is this normal?? Are they growing upside down or something? Cheers

I have found internodal distance and how bushy your plant is is mostly strain dependant and has very little if any effect from differing light setups. agree or disagree?
