   Germination/ Vegetation

   The cloning solution that I germinated the seeds in worked well and seemed more than adequate for the first few weeks. No burn or stress was detected during the first two weeks. All seeds germinated fairly uniformly with the exception of one, which was culled from the grow due to excessive height. The stems were adequate to support growth initially and the root systems developed very quickly with no problems.

   I found that at three weeks the seedlings suffered slower growth at 250 ppm, after raising the concentration to 450-500 ppm, I noticed an immediate improvement in growth rate. I’d advise watching for any slowdown during this period and responding with an incremental raise in nutes until you see a slight tip burn, then back it off a bit by diluting your mix with straight water.

   I ran into some serious PH fluctuations with three of the plants at week 4 and very bad Potassium deficiency was encountered at week 5. These problems disappeared when I switched to my Flowering nutes and started 12/12.

   I am using a 5/5/10 mix with my biggest mom currently and she is doing quite well at 4 months old. I would recommend supplementing Potassium and Magnesium if you plan to veg past 4 weeks.

   Flowering:

   I progressed from 800 ppm – 1100 ppm – 1300 ppm – 1500 ppm in two-week intervals. I never really felt that the plants were receiving optimal nutes until 1500 was hit and slight tip burn appeared on two of the plants. I will go with a more aggressive feeding schedule the next run, maybe start at 1100 and move to 1500 after week 6. PH remained rock steady at higher levels and I was confident enough to lower it to 5.2 for all plants in the final weeks.
