your temperature should be around 27 or 28c and your humidity should be about 40 or 50% now that you are 5 weeks into flower, you don't want high humidity in flower otherwise you risk getting bud rot

Yeah they ain't cheap to be fair mate, I found one online here for like £700 lol :bigjoint: https://www.coleparmer.co.uk/i/hach-dr-300-chlorine-and-ph-pocket-colorimeter/9957382?PubID=UY&persist=true&ip=no

When you make up the 1.0 EC stock solution do you use RO water? Or can I use my tap water that's 0.6 EC and then add 0.4 EC of pool shock to get a reading of 1.0 EC? Or if my tap water is 0.6 EC should I be adding 1.0 EC of pool shock on top of that to get a reading of 1.6 EC? Sorry for any...

I would leave them on just to see if the problem gets worse and keeps spreading to the rest of plant, they will naturally fall off anyway so I wouldn't bother cutting them off. Hopefully now you have give them a boost of nitrogen the problem won't get any worse :bigjoint:

Thanks dude, I never knew that. I guess I will need to invest into a chlorine test meter. I never knew they existed to be fair. I think to start with I will follow what you originally said and use 1 or 2ml of h2o2 per liter of res water and see how I get on with that :bigjoint:

I'm just super confused man because my tap water is about 200 or 300pm and I'm not sure if I should be using RO water to make the stock solution or if I should add it to my tap water and add 500ppm of pool shock ontop of the tap water ppm or what lol I'm super confused and I am high which only...

Yeah you are right lol the UK has been getting super expensive lately. How much would be needed for a 100 liter reservior then if a 5g tablet is enough for 2500 liters? I'm guessing 0.2 grams of pool shock per 100 liters if my calculations are right? lol :bigjoint: I could always make a stock...

It's a really nice smoke to be fair, I had a pheno that had super gassy terps and purple bits running through the bud, it also had a rock hard bud structure. And i'm using a Lumatek LED light at the minute which gives me a slightly bigger yield compared to HID or HPS bulbs. And I've got a...

What would you say is better dude? Would you say pool shock is better then using h2o2 in my res? I was taking a look at this old post and it says I can make up $2000 worth for $4 https://www.rollitup.org/t/make-2200-worth-of-clear-rez-for-4.423650/ on page 4 they go on to say that they make a...

I will be starting some Fish scale by Cookies in the next few months, I did a grow of it just before Christmas and it was super nice :weed:

She is hungry. It's a Nitrogen deficiency

Do you know what product I should use when it comes to pool shock because there is a lot of different brands. Will this do the trick? https://www.ebay.co.uk/itm/235419694161 And do you know how many grams that will equal to 100 liters of water dude?

Hi guys, I have been hand feeding daily in coco for the last 10 years and I decided to get a 100 liter flexi tank and I am wondering how much h2o2 or chlorine I should use in my reservoir to stop it from going slimey and smelly? And what is the best to use in a reservior? is chlorine or h2o2...

I believe the best timer on the market is this one. It's called the Time-R digital timer https://hollandhorticulture.co.uk/products/time-r-digital-timer

Thanks dude :bigjoint:

Thanks man. I'm just a bit confused with it all because I've been hand watering for the last 10 years and I've never done an automated system with a reservoir and stuff before. So do I just add 100ml of hydrogen peroxide to my 100 liter reservior every day or do I wait for all the water to be...

I was thinking about using the Hydrogen Peroxide (11.99%) but I'm not sure how much I would need to add to 100 liters of water in my reservior and when I would need to use it. Would I use it everytime the reservior is empty? After each time I re-fill the reservior?

Between 500 and 600 grams
