I've been growing 5 dutch passion power plants, I'm nearing the end of week 7 flower, and the buds just don't seem to be forming very well at all. I grew the same plants the previous batch, and they came out with nice, plump, frosty buds. By week 7 the buds were fully formed and the next two weeks were just ripening and expanding. The way they look now at 7 weeks, i'd expect them to look at 4-5 weeks. I have them in the following setup: 2 x 450W 11spectra LED lights 1 x 600w HPS 2.4 x 2m x 2m grow tent Soil with alpaca crap Cyco A+B, Potash, Swell, Liquid Kool bloom, molasses TEMPS: We are having some very hot days here at the moment. On a normal day, the temps are sitting at around 30deg C. On a hot day, temps can get as high as 33-35deg C in the tent, and at night when I'm running the lights the temps sit between 30-33deg C (on a hot night). At the end of the stretch period, they got a little bit bleached and heat stressed as they got too close to the lights, but I've moved them back to a comfortable height. Now the plants don't seem to be showing any signs of heat stress. FEEDING: All feeding is ph'd at 6.2. I was overfeeding slightly and the tips of leaves were showing signs of nute burn, so I've flushed them and have backed off a bit. DEFOLIATION: I read about defoliation and removed a great deal of the upper fan leaves at the end of the stretch period, and at around 40 days. I'm a newb at this, and I'm wondering if I've overdone it and it's affecting the bud growth? AIRFLOW: I also considered airflow, I have a oscillating fan in the tent, an inline exhaust fan and a passive air intake. A couple days ago I added a centri fan on the air intake to pump a lot more fresh air into the room but so far I haven't noticed any significant changes. The buds just look all stemmy, with little balls of hair but very little bud formation. There is about as much thc formation as you would expect on buds that size. Also, I came into the tent today, and it looks like the tops are trying to stretch even more. I've checked and double checked all my timers, I've checked to see if the lights are turning on during the day but this hasn't happened. This was a 9-9 1/2 week strain last round, so I'm worried I'm going to get some poor bud if something doesn't change quickly. The things I've done differently since the last grow: Lighting: LED lights; I have some lights from eshine systems, 11 spektra which are supposed to be pretty good. The plants were loving them in veg, I'm wondering if not so much during flower? However I do have the 600w digital HPS in there which should be creating some bud formation Defoliation: I defoliation most of the fan leaves, I think I may have overdone it....opinions? Temps: were about the same Airflow: slightly less than last grow - this has been resolved Nutes: pretty much same, I've added liquid kool bloom (low doses) I hope thats enough info to get some help. I would appreciate any assistance I can get. Thanks in advance!
