Im using a flood and drain pvc system in a closet usig a 500 watt halagon light three feet above plants and two 40 watt flourecets four inchs above the plants that is on 24\7. The halagon is used occasionaly to lower the humidity but it raises the tempto 90 but as soon as problems occoured the halagon was not used and temp remains at 75 to 80 and humidity at 60 to 70. I have been using Peters all Purpose plant food 20-20-20 at abut half strength. plants are about four weeks old and eight inchs tall and were doing well untill about three days ago which then I changed the water andstopped using fert. The problems I am witnesing are: limp leaves yellwing of some leaves and brown spots on the lower leaves. What is causing these problems and what are some solutions to them.

g'day,Sorry to here about this ****e scene ya going through!!!!I think we need to know how many plants yu got,and how often the system is flooded & had you changed the nutrient in the past 3 weeks? I dump my nutrient every week,keep a close eye on the PH --& use a bacteria killer in my nutrient.And since i changed my source of water (from rain to tap) every things gone fine.but PH is the thing I think you need to look at {if not already}...WISH YA LUCK ozi-grower!!!!!!!!!!!!!!!!!!

you still didn't mention ph level mate.it could be an important factor.

have you got any form of constant airiation or water pump flow in your resivour cos just the flows back and forth are not enough to keep the water charged. the more agitation in your ressy the better ph of 5.8-6.2 should keep them healthy the larger your ressy the
more stablilty for your ph. keep on toking
