first,how do u water? do u flood each watering,if so check them on a weigh scale,as wen they droop for water.if u do flood,and plants are taking up waterkinda fast ,but plant lookin not growin properly,too much water.now if flood methodnot workin,try measuring the amont ur given now,and on next water reduce that amont by 1 ounce,eah time until plants lok better.u can also find out how much water ur soil holds,and give them 1/2 that amont.then some people lik uncle ben,watering twice a day?it works for him,but ull be dam if ull be doing that,i just dont water that much.i dont flood my plants,wen i water ,i only flood wen i transplant to 4inch pots,or 6-12 inch pots,on the third watering,then ever watering after that,a few ozs-4oz or 4inch pot-6inch,8ozs for 12inch pot,the monts can very with row conditions,under florescents,and 70 watt hps.i had a problem similar to urs,i started i seed starter cells ,everthing fine,but wen i transplanted,to 6or 8 oz cups,everthing ok,but not doing really well,then to 5inch pot,lik i did for last three yrs,then, all sudden not workin,at all,played with the watering and nothin,somes transplan to 4inch sq. pots,2inch of strofoam,on bottom,and the rest poting soil,sams choice,then presto everthing is fine,then went to 6inch pots,good to go.i knew how to adjust watering,and fine tune,my last option worked well,maybe that can help ya,been there and done that.wen eerthing wasnt workin i changed pot sizes,for first time in three yrs....shewww.....peace buhead and the beviss/crusader....
