Hi everyone. I’ve got a nitrogen deficiency with two of my plants (CBD Python) in week 7 of flower. It’s not terrible but it is beginning to climb the plants. Do I want to up the nutrient at this late stage or ride it out until harvest? They should be ready at 9-10 weeks. Thanks.

I’m just wondering if growing using organic nutrients makes your yields suffer? I’ve been using bio bizz nutes and light mix, I’m very happy with the results but my yields from two Blue Mystic autos are probably not going to be much more than an ounce. I’ve had no real problems with the...

Hi everyone. My blue mystic autos are 10 weeks from seed and have been largely problem free throughout. Some of the leaves are starting to yellow now. I’m not sure if this is normal at this stage of whether I’m running into nutrient deficiencies. Nivarna say this strain should take 9-11...

Hi everyone, my blue mystic autos are approaching 9 weeks from seed and I’m just wondering how much longer they might have to go. All the pistils are white still and they appear to still be fattening up. Do they fatten up much more once the pistols start to turn brown or not? All the buds are...

It’s freezing here, daytime temps are no more than 4 or 5 Celsius. I’ve set the plants night period to run through the day and minimum temps are around 18c, maximum about 23c in the tent. I’m going to switch to 12/12 in the next week or so there will obviously be another 6 hours without...

i’m swapping my LED for an HPS lamp, mainly because im struggling to keep the heat up and having to use heaters to stop it from getting too cold. For the extra money I’m spending on heaters I might as well run a 600w HPS instead and get better yields (hopefully!). As I’m still in veg is it...

Where exactly do manufacturers get their claims of equivalents from? i am using a viparspectra 450 (200w) which they claim is equivalent to a 400w hps. Do they relate this to yield or light penetration? Whilst I’ve been using the viparspectra for veg I think I’m going to switch to a 600w...

I’m using Biobizz light mix with Biobizz grow for my first grow, I want to keep it all organic if I can. I read somewhere that the light mix has a pH of 6.1-6.2 so you should water with pH 7.0-7.3 rather than 6.0-7.0 as stated almost everywhere else. Something about the compounds in the medium...

Hi everyone, I’m a new grower from th UK. I’m growing some CBD Nordle in a tent with a Viparspectra 450 reflector light. I’ve read some bad reviews on other forums about this light but it seems to be working ok for me so far (only 3 weeks from seed though!) it was recommended on the...
