Thank everyone for help but.. the plants didn't gained any size in almost a month.. It didn't die but the already excisting leaves reduced size in more then 100% and started to lose color. It isn't dead but I decided to put the lights off since today, it's over they won't ever recover. I...

Ahaha, such a comment is lovely! Very usefull critiscm,advice and predictions, all three in one! And that's true it's an awesome learning experience. Next time, I'll think twice before growing MJ , haha. Okay fine, I will do that, the next time I water them, should I add again 1/4 fertilizer or...

To be honest, the two comments above don't make me any smarter, anyonelse with some usefull critism,advice or predictions? Can't really use this kind of critism. Thanks

I think it do was a micronutrient defficiency. Some yellow restored back green, judge yourself and compare with the two other pictures taken before. But.. the micronutrient problem is solved but some other leaves browned even more (fertilizer burn)? So I don't really know what to do now, let...

Thanks, I will keep you guys updated. Also, when I transplanted the plants several weeks ago (1-2?) I couldn't see any roots only as close as 1,5 inch from the stem but anyhow we will just wait and see. Thumbs up!

Many thanks, I've done the steps you said. pH was good (5ml / 1000ml). I've fed each plant 330ml, nothing drained out of the bottom (2l pots). Another question: When I compare my plants to others it looks like mine is growing really slow :( It's already in it's third week and if I...

Actually, growing cannabis is a lot complicated then I thought it would be, it demands much more then the average plants. But anyhow here is a picture of a liquid fertilizer I bought, it's the best I could find for the vegetative fase for cannabis. View second image, the first one is turned...

Hi, New growth is looking yellow on 2 out of 3 plants? Cotyledons are completly gone, could it be a defficiency this time? Or somethingelise? Help please and fast , thank you very much! Thanks! Edit: I did water them two times in a week but I did not checked pH but I did checked pH a week ago...

Again, no clue how they are doing, you tell me! I did notice that the tips of the leaves became more brownish, the pics tell the story. (UPDATE: Cotyledons are 80% brown:) )

Since it's almost 30cm long I can be quite sure it's actually pure 150w and not equiv. Would be quite strange to have a 30cm long and 9cm wide but only 42watt CFL bulb. Lumens isn't metioned anywhere but it should be around 9000 I guess, it's sold over 70 times so I don't think it can be that...

Again, many thanks for everyone (in special Hush) supporting my project, every comment is appreciated! I'll do my best finding 6500k bulbs, Ill let you guy's know and will post more updates with photos over three days, might ask some more questions tomorrow about the lights that I'll buy. Thanks²

UPDATE It's hard to tell if the plants are doing okay if you aren't experienced so I let you guy's judge here are the pics. As you can see it isn't going perfect, but I don't know wheter it's good or bad, you tell me! (Multiple opinions are appreciated!) What are the brown mini spots in the...

Just stumbled up on this auction...

Emailed him, the light spectrum is 5000K Which probably has a peak in the early 400nm's? I think it isn't that bad, maybe I'll buy two and use a splitter. About the heat, do you guy's think it will be that bad? I am able to buy two new 6-7inch fans. I do know that "T5 lights" or other may be...

I've did some "research" and it looks like it isn't a scam: "Self-ballasted lamps[edit] As of 2012 several companies started to offer self-ballasted metal-halide lamps as a direct replacement for incandescent and self-ballasted mercury-vapor lamps. These lamps include an arc tube with a...

Think I will be buying a 400watt MH lamp. hXXp://www.ebay.co.uk/itm/130895144786 What do you guy's think? Although 22000 lumen is low for a 400watt MH lamp, it's self balasted and cheap + more then enough for my three plants if I combine with current CFL 125w.

;)

It isn't a real room, actually. The 1.8sq ft can change to x sq ft when needed. I know a lot of people that use a lot less lumens and light then me so I think the light won't be an issue. 12500 lumen for 3 plants is more then enough if theyre online staying till week 7 which is only five...

Thanks a lot! The light should be fine, a1bout 9000 lumens on 1.8square ft. When the three additional lights are placed it will be 12500 lumen for 1.8square ft for the moment. I am prepared to buy additional lights if needed and additional fertilizers online specialised for marijuana but we...

The pH is claimed to be 5.0-6.5 of the coco peat soil itself. But because I added 30% of 7.5pH perlite I think I should be fine? Or does this not compensate? Our tapwater is pH 6.5-7.1 and normally has a high content in calcium but because we have a "calcium remover machine" (don't know how...
