Slow Growth

I'm using a 600 watt hps in combination with (2) 4' agrobrite fllorry's, along with blood meal for nutrients... I have excellent temperature conditions, excellent ventilation, I will be getting c02 in a week or so.. but I am noticing what seems to be slow growth... could my light be to far away? Or is it a nutrient problem.... I will post pictures as soon as I can... Please Help...

Not enough info....could be a plethora of things... How old are they? Are you watering too much (could they have root rot?)? How's your soil? What is your ph like? I could go on....lol..... There are some very knowledgeble people here, and they can help with more info and photos.

Like I said I will post pictures very soon... But my soil is good...not much chance of root rot...I'm not over watering....I balance my ph before watering.... and they are about 3-4 weeks old... they are very healthy but I'm just not getting the growth I should be.... It might be due to lack of c02 and fresh air...I'm gonna go take some pictures and start a grow log...

Well, I haven't seen yours but, looking back through my log I had an explosion of growth right after 26 days.....you did say they are healthy, so it sounds as if there might be no problem....I look forward to your log.

Happy Tokin' and Growin' :jointsmile: Bree

COUld be any number of things.

Fresh air or lack of it will certainly cause problems, but you do NOT need cO2 to fix it. In fact, if your problem IS circualtion, flooding the space with cO2 will only help to make the problem worse.

Co2 will be good if other conditions are good. But it wont help a bad grow get better.

Here are 28 days old plants from seed I grew a couple years ago...under good CFL and good temps. One is indica the other is sativa... the one with the tape measure is at 31 days.

You might reconsider adding anything until you figure the issue out.

Good Luck.
