    Brown patches on leaves overnight..

    I’ve been battling with these seedlings like never before, had them in party cups in flood and drain for a month or so.. Been trying to combat magnesium deficiency for a while now too. They’re in coco btw.. Just when I thought I was on top of it these brown splotches appeared overnight and I’m...

    Anyone using mixed spectrum CMH/HPS?

    I’ve been flowering with CMH for a little while now, mostly with the 630de units although I also have a couple 315 units that I move between veg and flower. Overall I’m happy with them, particularly the quality that they seem to provide. I’m looking at extending my flower table from 8x4 to 12x4...

    Gavita 600/750 Flex vs 1000DE (dimmed)

    So the reality is that I don’t quite have the ceiling height for the 1000de Gavitas but I do for the 750 Flex.. Where I am the supplier only brought in the 1000’s though because the pricepoint between the two is actually pretty close. Is there any reason why I couldn’t just run a 1000 and dim it...

    Installing mini-split, need advice on vented/sealed and co2

    Ok so after much thought I’m installing an18000btu mini-split in my flower room next week.. I’m currently running 1890w of Cmh over a 4x8 table but I’m plotting on adding a further 4x4 and another 630de Cmh for my next run as it will just fit. I’ve been growing for a few years now but I’ve got...

    I have my flower room inside my garage, it’s completely sealed off and partitioned. I’m looking at A/c options and I wanted opinions on whether I could mount the compressor unit which is usually outdoors inside my garage on the back of my flower room wall..? My garage is pretty large and fairly...

    Calcium deficiency late in flower..

    I’m six weeks into flower on my current run and my one strain has definitely got a calcium deficiency. I was planning on giving them nutes for a further week before starting a two week flush. The buds still look really good. Is it still advisable to add cal-mag to my nute mix this late in...

    Add Cal-Mag to a mixed res..?

    I've got a calcium deficiency for the first time since I started growing, just in the one strain. I’m getting some cal-mag tomorrow but I’m not sure if I can just add it to my existing mixed res..? I run DTW. Is it better to wait until I mix fresh one to add it? If so is there a specific order...

    How to stop res gravity draining through pump..?

    I’m looking at getting a bigger res and the one I’m eyeballing is a taller narrower one than I currently have.. I could save a bit of space with this shape. The problem is that my tables will be lower than about the top half of the res and would cause my solution to drain out through the pump...

    Advice on new veg area ventilation

    My current area is working pretty well but I’m figuring there’s enough space to convert part of it into a small veg area.. I don’t want to have Moms any more and I’m looking at running fewer larger plants in the future. I want to take cuts from my vegging plants just before I flip to 12/12 and...

    Phosphorus deficiency..?

The plant is in a 6” rockwool block that has been transplanted into a pot of coco after I decided to...

    Please help diagnose this leaf issue..

    Hey all I’ve read through the sticky’s and checked what I can on charts but I can’t seem to find these symptoms. I really really don’t know if it’s a deficiency, toxicity, pests.. I really have no idea. Top feed hydro in Rockwool cubes. There aren’t many leaves with these symptoms and I’ve only...

    Which weeks of flower to add more light intensity?

    I have searched but I couldn’t find much on this subject.. I have some power restrictions unfortunately so my question is fairly simple.. Assuming an 8 week strain, during which weeks of flower would you add more light to increase yield? I have read somewhere that towards the end of flower...

    Pre harvest flushing rockwool

    I started flushing with ph’d water three days back but it looks like I’ll have to cut in a few days.. I don’t want to wait longer as I prefer my trichlomes when they’re mostly milky and only a small percentage amber.. I water/feed my 6” cubes twice a day, will adding an extra watering make much...

    Concerned about possible bud rot, any advice welcome..

    I’ve made a bit of an error on this run and just need to try see it through the best I can.. This is in a 3x3 tent and I’ve got too many plants in there it seems. My next grow I’ll be flowering out of the tent so I shouldn’t have the same issue. I’m concerned that my buds are way to crowded and...

    How long can I leave clones in Aerocloner?

    Ok so I had a stab at making myself an Aeroponic cloner.. I took cuttings earlier than I normally would have as I was unsure of how successful it would be and if it didn’t work that well I would use seeds for my next grow. It seems to be working ok though.. this is my first batch of Aero clones...

    How does growing in an open area differ from in tents?

    Ok so I’ve got a stealth vented room of 7’x14’, the height slopes from 6’ to 8’. Inside the room I have two 3x3 tents which are 6’6” high. I also have a counter where I keep my Moms and clone on. My question is if I put my Moms and clones in one Tent and left the rest of area open what options...
