First Grow, Bagseeds, Come take a look!!!

Wow thanks, I really appreciate it, ill definitely take a look

Well i know that low RH (relative humidity) can stress the plants cuz they use a lot of energy for transpiration.

so if that is the case... maybe you are on the lower side 20% for more than it is higher.

how high are your lights? they might be far enough to not burn the plants, but close enough to dry out the atmosphere.

i dont know how well this works, but if its an enclosed area, ive heard putting bowls of water to evaporate increase the RH.

so id say check the RH as often as you can to see if its coming out lower more often than higher, maybe raise the light a little bit.

can we get some pics..??dyin to see how these babies turn out and what u yield from them

Id say the light is about two and a half feet above the top part of the plants... but the reflector id say is only about 2 feet... right now the temp is 72% and the humidity is at 30%... I usually keep the closet door closed except for a crack. It keeps it pretty humid in there... Ill close it again and leave it cracked and check the humidity when I get home from work... Opening the closet door lowers the temp and humidity... I gotta head back to work... Ill be back in like 3 hours. thanks everyone! let me know if you want more pics (havent really changed) but I can take specific angles and whatnot if you want.

ok. sound good.

yeah just check the readings so we can keep eliminating possibilities. ill try and look into some more stuff for you.

ill be adding some pics tonight too...the aks have just exploded since my last post.

ok just got home and went straight to check the temp and humidity... this is what I found. temp: 77.2 humidity: 32%. Both of those numbers seem to be in the right area... but im not sure, let me know thoughts and suggestions please. Also they feel dry, not all of them but some of the worse ones, like crispy. Like you know when you got a brand new stick of gum and you can bend it and whatnot and its normal, then you try bending a piece of old gum and its hard and cracks and snaps? thats the best example I can come up with, like I can fold the leaves and stuff, but they are more crispy then I think they should be. And the temp gauge thing is right above the top of the main plant in the middle... so it should be reading accurately.

hey, Im a newbie to the forum but not growing, I have a lot of info. Check my pics! Anyways, how often do you have to water and how much? Those look like 2 gal pots yes? Humidity in the vegetive stage should actually be between 60-70%!!! Your around 30? Thats better for flowering stages! Even then thats slightly low! Flowering plants like 40-60% humidity. This easily explains your dry,crackling, look and feel that you describe. Place a bucket or pan of water in the room and watch the humidity closely. Or if it's possible....a humidifier....or you can experiment with leaving the door open at different distances. just dont let it get too high...this invites pests and fungal attacks! (EEEWWWW) Hope this helped some.

That actually did help, Had no idea it was supposed to be that high, looks like some bowls of water are going in there. Here are some more pics that might help... far bottom leaves are turning yellow, dunno if thats much of an issue though. let me know how much longer you think I should wait until I start 12/12. Also on their next water Im going to start giving them nutes, what you think, 1/4?

The closet


Notice curly and wavy leaves


Crispy


My favorite startin to get tall


Fan and meters


Wavy


400 wat HPS and reflector


King droopsta


sorry for blurry (still trying to figure camera out)


Closet


More closet


Theres more


Thanks for looking lol, input appreciated. .......

Hey there looking better lay off the water just a little longer and dont worry about the bottom leaves to much.

I would wait until they are at least 12 inches before 12/12.

I know your in a hurry and I understand but if you go any sooner there wont be much yield.

Also what nutes are you going to be using.

ok, and I will be using Flora Nova nutes.

How old are they? PLants can start flowering cycle at two months old. Also, how tall are they? When they flower you can expect them to double or even quadruple in hieght! Usually only double to triple though. Are you gonna have enough room from top of canopy to the bottom of light fixture without burning? make some measurements. if they arent old enough but too tall....top them! Besides the humidity thing...they look great! start with 1/4 strenth veg nutes...lack of nitrogen could explain the yellow leaves....it might be time to fertilize...

thanks for the help... Ill toss some bowls of water in there soon... Id say they are about a month maybe a month and a week old... I will def. Hit them up with some 1/4 strength flora nova veg nutes next time I water. And the height of my closet is about 6-8 ft. and Im assuming I want the light to constantly be about 2 ft. above the canopy of the plants. So I think I should be fine without topping but suggestions are what I love

Your using a 400watt right? (MH or HPS?) 400's don't burn as hot as 600's and 1000's. Therefore they can be placed closer to plants, especialy if they are air cooled, have tempered glass, and are sealed up tight at the seams etc. 18 inches should be safe...I run a 400watt MH with an Agrosun bulb to add the red spectrum. My hood is 18 inches from the top of my tallest plant. The best way I know of to test heat is the back of the hand test. If you place your hand palm down under the light at the top of the canopy and it gets warm...the hood is too close. You want that hood as close as you can get it so lumens can penetrate to lower foilage. It's funny...your using a 400 watt and some T5's? Thats exactly what I have!

wow!!! they doubled in size since the last time i seen them!..they look good dude! hows everything going?!?

i transplanted my plants and upgraded my grow room if u wanna check it out!

this could be a matter of humidity, RH of 20% is really low, most meters hardly go that low. SO although the light might be great for the plants sake, it could be creating a dry environment around the plants....thats why he might need to raise it. i was pretty clear about that in earlier posts.

I had issues earlier on of the light being to low and burning them. i put a pot full of water in there so I hope that raises the humidity a little, what am I searching for it to be at? and Im using my 400 hps with a hortilux bulb to add blue spectrum.

Sorry, I spaced that...I guess I missed that post, thanks for catching it!....You are totally right. Uhm ok...Humidity in the vegetive stage should actually be between 60-70%. A Humidifier would do wonders if ya have one...or wanna spend the cash. Maybe the lamp could be moved closer once humidity is under control? Huh, you have the opposite ballast/bulb set up as I do. Im gonna have to time a grow with you and we can do some experiments! If your cool with it of course...

lol... whatever works big homie

im pretty sure its 40-60%...youd prolly be safe in somwhere in that range ..like 50% or so..

checked on em this morning and the humidity was at 30... im noticing some purple looking patches on the leaves, ideas?
