Everything looks pretty nice to me, i think that slight leaf curling down points to a slight nitrogen toxicity, i'd hold off on the grow big for a little bit and start hitting them with bloom nutes when they really start shooting up them buds

Okay ill hold off on the nitrogen.
Just kept feeding them grow big because thats what the foxfarm feeding says.
the feeding schedule says i should use grow big until week 5 of flowering.

I always use feeding charts as a guideline, reading your plants overrides it.

Its really only a super slight nitrogen toxicity so if you hold off for maybe a week or two before the next dose it should be fine.

My strains love nitrogen for like the first 5 weeks after i flip them to 12/12, so it totally makes sense that you would still want to and potentially benefit from using it, just gotta be careful with the grow big and tiger bloom cuz they are strong!

Thanks man. Will take your advice amd follow.

Do you have any link to a diagram with pictures of toxicity and deficiency?
I really cant tell them apart

I have always been a fan of 9 per light 3 wide by 3 long. This breaks up infestations or infection into smaller groups that can be easily removed with minimal loss.
How tall did you get them before flipping to 12/12? It can help me in my next grow. I did want to grow around that number but i had males and other grows said its not enough space

From the Topsoil layer to the topmost shoot, it should be 20" to 30" before flipping. Stay closer to 20" if space is restricted, and always keep in mind that the plants will continue to grow taller even after you flip the lights.

A great example in my experience was watching the difference between tented plants, that need more growing space, and open room plants that have plenty of space. The tented plants were flipped much earlier as their overall growing space was restricted. The open room plants have a wider spread, and need to be pruned, and kept from extending too far.

I too am inspecting for males at this moment. Good Luck! Private message me if you have any other questions, I'd be glad to help.

Hey guys i have a little heat problem and underwater problem. I was at work all day yesterday and couldnt water them until today. And when i opened my tent my big girl was all droopy and leaves cupping upward.

I was just wondering will she recover and should the leaves perk back up?

She'll look happy as ever tomorrow. I know Greenhouse Seeds's lets some of their plants get really dry at points in their bloom period and then water them; either way she'll perk back up no prob.


If they really need water they will droop like nothing else DIRECTLY AFTER watering, and then eventually look as good as new

Heres a little update

Day 36 Day 8 of flower

My big girl has perked up again and should be taking off now.

Is my light to close to the tops? I cant figure out a way to put my hydrometer or whatever you call it at the top of my plants. The light is about a foot away maybe a little more. My plants still seem to be having slight heat stress.
Temps at the bottom of the plant at top soil is 77-79 so im guessing the top of the plants are around 81+

How is it that some growers have 1 inline exhaust fan and a fan inside the tent to move air around and their temps are in the 70's. And mine is stuck in the 80's. Highest being 84 degrees. Can someone edcuate me more on circulation and temps
