Please!!! I need an emergent help from you guys (I know you guys are the expert growers) These guys have been growing in these pots since 2010/4/26 after germination for 7 days and today is 2010/5/14 (so almost weeks of growing so far). They show no problems at all until 6 days ago, one of the Bubblelicious#1 started to turn yellow on the very bottom leaf, newly growing tip and all the leaf's side tips...then starting since 2 days ago, almost all of them's bottom leaves turned yellow and seemed like they are dying, however, the top keeps growing at very slow rate as compared to beforeâ€¦ I have no idea what went wrong, my setting are the following: Light: fluorescent light 6500 K kept around 12K to 30K LUX Water: pH at 6.5; i try to keep the soil surface moist at all time (spray them twice a day), then water thoroughly once every 2 days Ventilation: air blowing at all time (not directly to the plants) Humidity: 55-65% at all time Nutrition: no nutrition given until i see the problem of turning yellow, i thought it might be the nutrition problem, so i gave water + nutrition (NPK 2.4-1.3-2.8) diluted to 2000 times (direction is 1000 times but i was afraid of over nutrition so diluted to x2) I started giving them 5/8 to all the plants but problem persisted and even more bottom leaves turned yellowâ€¦ Temperature: 73 to 76 F (23-25C) at all time #1 What should I do now? #2 Will my plants keep on dying until they are really dead? #3 Will my plants resume growing if problem solves? #4 Will yellow leaves turn back to normal green if problem solves? #5 Can I cut off the yellowish leaves without stunting their growth? Million thanks, and happy mother's day Million thanks, seeing plants growing like this is really depressingâ€¦and most importantly, I want to learn as well, thus I posted it here to ask you guys the experts and share with the people !!!
