First of all I am from Texas so we have tons of weed out here pretty cheap - so I have kept a selection of my favorite seeds over the years and I am now trying to grow them (it is a collection of mexican swag). I Right now I have six plants under a 48" shop light that has a light out put of 2200 per bulb (2 bulbs) that simaulates natural, full-spectrum light. They are planted in three gallon containers in a mixture of Miracle gro soil and perlite (80%/20%) - When the plants were babies they got that fly bug that eats the roots of the plant - so I used some dishsoap combined with water and sprayed it all over the plants. It seemed to get rid of the bugs. Well this time, the plants are now 6 weeks old and those damn bugs came back - so I put some ajax dishsoap in a bottle and have been spraying the plants. The plants are now dying from the bottom of the plant up! I think that I used way too much soap. It actually foamed on the leaves then I sprayed it. The bottom of the plants are burned and yellow and the leaves above that are droopy - IT IS NOT NUTRIENT BURN! I don't have a digital camera to take a picture --- but if I poisoned my plants is there anything that I can do to save them? i.e., replant them? I am afraid to add more water and try to rinse the soap out because of the catastropic effect it has already had! Also, should I grow my plants under an HPS system (I am buying one this week) during the vegetative stage or just the flowering stage?
