Thanks again guys !! Its an honor to be part of a(grow) family that has so many knowledgable and experienced people who dont mind helping and sharing(and arent condecending)..After reading thru many coco threads and searching the "lucas" formula/ratio, i have confused myself thoroughly ,lol(only kidding),, i have however found plenty of useful information that i will be putting to good use.. I have a habit of pushing the plants (sometimes too far), but will do my best to take it easy and let the plants tell me what they need, i have increased the feeding a bit (to 800ish ppm)and they are looking better and starting to take off,, i will give a thorough update,with pics when i update my journal,,next step will be to pop the 5 Humbolt Blue dreams and start my other 600 watt lamp(digital,and i will start at 200w and work my way up)..Cheers!!!
