Let me add that I am in the middle of my first "liquid organic" grow with the EJ line in ProMix HP(only amendment was worm castings). I can attest that dumping in a solution with a pH of 3.5-5 WILL cause lockout! I thought I could rely on the "herd" to make it right, but apparently at such a low...

I would like to know the same thing; Does the "natural occurring sulfur" in Crosby's black-strap molasses pose a threat to our plants? Or is it only if there's "additional sulfur added" that we run into problems? Thanks

Damnit, I'm having the same issues with my purple kush....I'm using technaflora's "recipe for sucess" and I'm pretty sure the curling and cupping is from too high an EC, and most specifically nitrogen toxicity. My EC was around 1150-1200 in 2nd week of flowering, but still using the veg formula...

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...

So do people recommend no lights for the last 2 days?

Only 7grams per plant, really? I was thinking of trying a 12 plant SOG in my 3x3 flood and drain table, under 600hps. Some form of Master Kush, as it was a rare seed found in a Master Kush bag and ended up being female. She's a mom and is huge! I've topped and super cropped her crazy to keep her...

What exactly do you mean by that? This is my first grow so I'm just trying to learn all I can. I've been flowering my Jordan of the Islands strain for almost 6 weeks now. Some plants have hairs already turning orange(just so happens it's the plant in the back corner I can't easily reach), while...

Yeah that one was directly under the bulb. Still a good 4" under, and not hot on the hand(only the glass is hot) but I think it was still just too much. Everyone has said it looks like heat stress so I've bent it out of the way a little to see if that helps. I am still concerned about the...

Just for the record my flood table has all the same strain, and my kush plant is in a bubbler in the other tent. My flood table usually has a pH of 6.1 when I check it, and I usually lower it to 5.5 daily(mainly during veg), but lately with the flowering nutes I've just been lowering it to 5.8...

Hey I have 5 plants 1 month into flowering on my table doing the same thing. My strain is 70/30 Sativa/Indica, and it's really bad on plant tops, but not all of them, and can in some spots be seen lower down. I did notice I changed my timer wrong, and had one flood(out of 2 a day) that was on...

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...

Hey I was told smart pots weren't good for ebb n flow because they never have a chance to dry, eventually causing root rot issues. Especially when filled with clay balls. What do you guys think about that? This grow(my first) I filled my whole flood table with hydroton(clay balls), all...

That sounds somewhat dirty, in a homocannabisexual type of way

Yeah i get tip hook too, and thought it might be too much Nitrogen as I had to use pH down every day which is Nitric Acid. I tried changing to a pH down that is Phosphorus Acid, but they're still doing it. I also backed my nutes off about 1/2 and they're still doing. pH is adjusted to 5.5 and...

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...

Really? But they're still so young and small, like under a foot....when is it best to top them?

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...
