Good afternoon all, I have attached images of each plant, are my girls ready? They are in day 68 flower! Unfortunately after my last post we had more very hot weather for a further 4 days, but it has cooled down now and the girls seem much happier. I am guessing they have been stunted due to...

Have just ran a test batch on a 3L mix, 1ml of A&B per L brings it to 300/400 PPM will try that + root tonic. I will stop using the univeral traces all together. One thing I have just noticed.. I thought I'd check my nutes. My first A&B BLOOM are a pale colour, I opened another A&B as I have...

What PPM / EC do you recommend? Cheers

Sorry for missing your question Deadstill & thank you for such a detailed reply. My tap water sits at 100/200 PPM - what strength would you recommend? I am sometimes using an extra traces which is an additive so I am thinking this is where the excess iron or other micro nutrient issue is...

No need to apologise, it is all a learning curve. Just hoping I can finish this grow as I have learnt so much over this time. It would be a shame if some plants didn't make it.

Not sure on res temp, shouldn't be as high as the room however. I tested the water and it was cool to the touch but no idea what exact temp. It must be a res issue as the other tank isn't showing signs.. full res change tonight.

What PPM would you recommend? I am using the Hanna scale. Cheers

I am based in Europe, hello from across the big pond! Ok note don the build up, my job tonight is to empty & re fill the tanks to a lower ppm. My tap water sits @ 100/200 ppm and this is on the 500 scale. What ppm would you aim for?

To add I do have small oxygen stones one in each tank. Thinking about increasing exhaust and intake power & have a controller so can control temps better but we will see have we go in the colder months first. I can confirm what I have tomorrow if needed + exact size of room I have a de...

Thanks for the replies. So this is my first grow me and a friend built the room.. attic.. next time would prefer basement or ground floor level.. Nutes - growers ark So it is a NFT system, 60 liter tanks, pumps on all the time, low/medium. Light - Maxibright daylight led 1030w pro on @ 50% due...

Evening all Hoping you can help diagnose a problem I've got , see image. I have 2 60 litres tanks, running at 700ppm and 6 - 6.2 pH, each with 2 plants in so 4 total. This girl is by far worse affected and has been like this nearly a week but doesn't seem to have got any worse. The other plant...

I am bumping an old thread but I want to say how helpful this has been, thank you NFT for all this information Not sure if you still vacate this forum but I hope you are still about Treebeard

Will look into this, this is for extraction/outtake? Would you upgrade intake as well? My original calculations are off on first post I will edit tomorrow with the correct CFM/m3h Treebeard

Can't seal 100% unfortunately, that was the original plan Intake is coming from outside Thinking of more powerful intake and exhaust to bring in more cooler air and vent the hot air faster Treebeard

Got 2 screens on Treebeard

Current schedule Lights come on at 18:00 and switch off at 12:00 In flower I'll schedule on at 18:00 and off at 06:00 What do you think about the intake/outtake fan power upgrade? That would bring in cooler air from outside faster and take warm air out faster theoretically. Treeebeard

Evening all My first in door grow in the loft is happening as we speak I will run into heat issues soon I think, at moment plants seem ok apart from I messed up on 1 tank nute wise but now seems ok Peak heat has hit 32c & it is only May. In July/August I imagine this will increase I have used a...

Great thread I am glad I stumbled across this I'm gonna apply things I've learnt here on my NFT system and save some cash I like learning from the masters Treebeard

Thanks for all the replies. I've sorted the issue.

Hi all First timer here I have set up a grow room in the attic, very well insulated, air intake + exhaust, 1030W LED, heater, dehumidifier, 2 inkbirds to control heat and humidity, carbon filter and I have 2 humidifiers. I have done a couple of dry runs & have my heat under control. I am aiming...
