8 plants not enough space, What should i do.

No, u want temps between 72-80 and a ten degree drop for lights off is a-ok

 

No ur fine I mean u can drop to 60 (10 below daytime tenps) at night with no worries

 

Sorry Ccoastal but I highly disagree, I don't know where you are getting your facts from but temperatures below 70 degrees F are too cold for almost all Cannabis plants. Ideal temperature for daytime should be 70-80 degrees F. Night temperatures should be kept over 60 degrees F to prevent stress, stimulate hormones and reduce stem elongation....at least keep the temperatures at 65 degree's lowest.

 

Disagree all u want 60 is fine if u don't think so go look at a grow guide I'm pretty sure High Times has one on YouTube. also cold temps stunt growth, not lead to stretching stems. I'm not saying u should drop below 60 but it's fine if ur at 60-62 at night, this isn't just coming from browsing around the Internet unlike other ppl this comes from experience. Are u really sayin he should go buy a heating pad over 3 degrees? Think about it.

 

Negative, I am not saying to buy a heating pad. I am simply saying what I think.

I also have a grip of grows under my belt. I am not under experienced.

So there is no need to get snippy with me, I am putting in my 2 cents like everyone else here, The route he chooses to go is up to him.

 

Lol ok, well saying what I know 60 is fine, being snippy? Look who talkin bro idk where u gettin ur info but..... 3 degrees is fine ive seen grows get to 58 with no major draw backs, also if u had a grip o grows u would know that cold temps dont lead to stretching plants, in fact it's quite the opposite

 

If ur really worries about low night temps, switch your timers around so ur dark hours are during the daytime so it doesn't get as cool

 

Like what you got going on COD and I totally understand your thinking on the starting numbers. On the grow I'm doing now I started out with 3 reg. Colombian Gold, 8 Bagseed, about 10 days before 12/12 flip I added 2 fem. Church. When I look back on it it seems like over kill but right now 3 weeks into flowering I have the 2 Church ladies, 1 CG, and 1 Dank ass bagseed. Oh and I also got 2 of them in 13qt. trash cans like you they work pretty nicely. As far as the lower night temps. Are you running your lights at night if not try switching over to that and leave the bulk of your dark period for say 10 am to 4 pm. Then do something like 9Pm to 9Am for flowering. I would stress those temps long as it don't get much lower. Remember in mother nature it gets pretty cold some spring nights.

send emm to me

 

I run my 400w about a foot above the girls, so lights too close should not be your problem. They love it and stay short and bushy and they are sativa's

 

Your plants are asking for phosphorous (p), it's either locked out due to too low of a ph, lacking in the nutrients that you are using, or lacking in the soil, and i'd hazzard a guess at the ph being too low. Now you need to look at why it's too low, and it's usually that your plants are being watered too often, leaving them without a dry period (wet to dry cycle) that they need to increase the ph of the soil as it dry's out and gains o2, or the water and nuted water that you are feeding them is too low. P like 6.5-6.8 in dirt.
You can spoon some bonemeal or seabird guano over the top and water down thru it, that's what i do when i put a plant into flower, the transition period is really really nutritionally demanding. Especially for phosphorous. Good luck.

 

Lookin pretty good, still needing a higher ph I'm guessing cuz I'm assuming u r feeding it well but it's still turnin a little red, meaning phosphorus is locked out most likely from a low ph, u can use 1 tbsp baking soda to a gallon of water poured around the base of the plants, don't folar feed tho it will plug the leaves, like the guy before said it could be from not giving it enough dry time before waterings but still looking good mane

Good luck!

 

looks like she hungry for nutrients.
