Did some fim'ing/topping/supercropping a few days before going away for 3 days. I also changed the light from a 110w floro to the 300w MH. Set EC to 400 and pH to 5.2 the day I left, and when I came back it was EC 500 and pH of 7. They get flooded every 8hrs, and air temps are around 23c...

Ok my rooted clones that I transplanted into 16oz cups are looking bad. The new growth seems small/stunted and is bright lime green, and some yellow. Clones were rooted in Root Riots, then transplanted into "Professional Potting Soil" with more perlite I added, then I watered with a...

Hey just wondering if the red and green lights on my power bar that are in my tent would cause issues with the dark period? The power switch is lit up red, and the indicator lights for fault protection are green. The red one is the biggest, but probably still LED. Anything to worry about in...

Topped a few of my plants today, and think this one might be a male? Plant is around 2 months in veg under 24hr light. What do you think?

I have to adjust my rez pH down to 5.5 from 6.5-7.5 once a day. I use Technaflora's pH down which is Nitric Acid. From my research, Nitric acid breaks down into Nitrogen for the plants. I have leaf tip "hook" on my fan leaves. My EC is only 0.8-1.0 with no other signs of nute burn. Any...

I'm getting ready for my first outdoor grow this summer, guerrilla style. I'm totally overwhelmed with all the soil mixes I read on here, not knowing what is best for my conditions. So I thought I'd see what you guys have to say about it. I'm going to be growing in the Cariboo region of BC...

Hey all! This is my first grow and I've got 9 plants(Texada Timewarp 70/30% Sativa/Indica) in a 3x3 flood and drain table. 2 are growing taller than the others, and 2 are quite short. The one in the back corner of the table is the tallest of them all, and isn't filling out like the rest...

I am able to pull some of the brown roots off easily, as if they're slimy, but I'm not sure if this is root rot? There isn't really any "slime" that I can see...just the brown squishy roots. Rez temps are 66-68. Nutes are Technaflora's "Recipe for Success" (BC Boost, BC Grow, Thrive Alive...

This is the only plant out of my nine that really look like this. It's like one half of the leaf didn't form properly, causing the leaf to twist sideways. The new growth seems to be ok, but I'm not sure what is going on. They were stressed a couple times over the last month moving from their...

My plants are starting to look a little sad, any ideas?? My EC is around .850, ph is 5.8-6.2 and they are now getting watered every 6hrs for 15mins. <EDIT> I've backed it off to only 10mins just in case they're getting over-watered. Thanks

Sorry if this is a dumb question but I couldn't really find an answer. I'm basically just wondering if I add all the NPK(and other micro's) values together to get total? Example; BC Grow is 1-3-6 and the Boost is 3-2-0...if I mix at recommended amounts, will my total NPK be 4-4-6??(the two...

Hey I'm a little confused on the NPK ratios that are given. I understand it's the ratio of N to P to K, but is 10-10-10, ten times as strong or concentrated as 1-1-1?? I read a lot about cannabis fertilizers, and see lots of people recommending 20-20-20 (not sure if they're talking soil...

I have a problem with most of my seedlings, and that thread is here https://www.rollitup.org/marijuana-plant-problems/410885-please-help-me-my-droopy.html But in trying to get more info, and searching the web, I haven't come across another case of a seedling doing the acid trip surfer dude...

I have 10 seedlings and would like to be able to fit them all on a 3x3 table. I want to sex them as early as I can, kill the males and then turn the remaining females into moms. What size Smart pots should I use so I can fit 10 on a 3x3 table, but then also allow enough room to grow into...

:-(What do you guys think? This is my first grow It's been 7 days since I put the germinated seeds in the Root Riots and put them in this tray. I have maybe 4 days more max until my veg equipment arrives. Temps range from 68f(20c) to 85f(30c). Relative humidity ranges from 25% to 35%...

For my first grow I thought I'd do DWC, but then I realized I can only fit 9 5gal buckets in my tent(4'x4'), but I have 10 seedlings so I have to rethink my veg setup. I think Ebb n' Flow (flood and drain) is the better option for veg. That way I can take out the males and then use DWC...

I love the Undercurrent design, but unfortunately I'm in a tent, so the rigid PVC won't work. I want to run a set up like the Undercurrent, but instead of PVC, I want to use 1" flexible hose to connect the bottom of the controller to the buckets, and then somehow reduce down to 3/4" for an...

I'm looking at all the available EC test pens out there, and there seems to be 4 main options for how it's displayed. Is µS/cm the preferable resolution(0 to 1999) or mS/cm( 0.00 to 10.00)? Lots of people on grow forums seem to use a 1.0 type value when talking about EC, so I guess that...

Well I might have jumped the gun and germinated my seeds a little too quick, as my vegging equipment isn't here yet. All 10 seeds gave a tap root within 48hrs and I then transplanted them into Root Riot starter cubes. Now today (less than 48hrs after going into cubes) a few of them have a...

Hey all. I'm feeling a little stressed and short of time, trying to get everything ready for my first outdoor grow this summer. I'm shooting for around 50 outdoor plants set in 5 or so different sites. Since it's my first grow, I'm assuming I'll only harvest 1/5 of that, which is why I'm...
