I have done a good amount of research but would like some more input. -Im using Sensi Grow Two part Grow/Bloom. 4 plants, Three headband clones about 3-4 weeks old, and a lemon haze seedling that is almost ready for a pot. - My plants are under a 600 watt metal halide for veg, HPS for bloom. - They are in a 4 gallon reservoir. I also have another 4 gallon res that pumps by Vidx">water through the plant res. - I have a by Vidx">ph meter, and ppm meter. The ph is steady at 5.8-6.0. No humidity/temp meter. \t- Ventilation is an inline fan, and a small fan blowing on the plants. -Problems thus far include. \t1- Purple stems \t2- algae in the res (Fixed by using another external res, ancient forest, and some other things.) \t3- White spots on leaves \t4- yellowish-brown leaves \t5- brown spots on leaves Here are some pics. \tANY SUGGESTIONS WOULD BE MUCH APPRECIATED!</blockquote>\t \t \t</div>\t</div>\t</div>\t </div>
