This is my 2nd grow and my 1st was a big failure. im using 400w hps, 10gal, dwc, 6plants,bagseed, ph 5.5 ppm 265, 4th day switching from something wack to FloraSeries. my plants are now 23 days old and i added 1/2tsp superthrive and i also added 1tsp of epsom salt in 8gal of water for the first time (dunno if the salt was necessary but i thought i'd try it). i hope this is not too much ST for my plants. hope they wont be fried by tomorrow but let see how this works. here are the pic b4 ST and the soil pic is a day apart. i added 2drop to 32oz then sprayed it down but i didnt notice anything the next day so i added 4 more drop and water it again and it look so much better. im mainly concentrated on my hydro. the soil mite be outside or something im experimenting on that too, well not really i just got extra sprouted. please leave all your comments and suggestion. help me experiment this stuff.
