Hey guys I have been trying to grow since September of last year. After a few ups and downs and finally getting past the seedling stage I have a crop that's about 3 weeks into flowering let me know what you think. There are 3 females (out of the 11 original) in General Hydroponics Water Farm (8-unit) under 400watt HPS. I used 400watt MH for the vegetative state and 2 25watt T7 florescent for seedling stage. I am however woried about the yellowing of the leaves I have read here on these forums that it is common for the Nitrogen to be moved up the plant for bud devolpment but on one plant it is starting at the top and the other barely has any leaves that arent yellow and it isnt late in the flowering stage yet. ( or so I think). I am using GH flora series just the micro and the bloom right now the feeding is 8ml of micro and 16ml of bloom per US gallon. my ph right now is 5.8 and has been between 5.5-5.8 for the past 4 weeks and ppm is at 1040, and has varyied very little in the past month as well (about 50 ppm difference). I also should note that the topped plant (the one with most of the yellow leaves) has been under the HID lamp the longest. I didnt have enough room to put the other females in because of all the males I had. Alright enough BS heres the pics.
