Barney's Farm Run

Another BIG week for the gals. They got lollipopped on Monday and it took them about 5 days to fill back out and start stretching vertically again. Saturday-Monday they seems to explode overnight, had to adjust the scrog net and do additional LST to keep the canopy as level as possible. PE#1 is not as tall as the others and with this system I can't really stand her up on anything. Hope that she catches up this week. I discovered some purple petioles, and a little spreading to stems on each plant and read that it's likely due to a mag deficiency. I added CalMag to the res. Also noticed the water temp is a little warm at 26-27C but I am not going to spend the money to get a chiller and pay for that electricity, so we will see what happens. Doesn't seem to be too big of an issue right now. To counter this a little I turned on the autopot air domes. Hoping that the extra oxygen will do them well since the warm water is likely low in DO. This week the light was lowered to 45cm above canopy. Reading back through old grows it appears between 37.5-45.5 is the sweet spot for this light. I also started checking the pH and the ppm's of each tray and noticed that the pH rises slightly from tank to tray. Tank is at 5.5 and trays are 5.8-6. Something to keep an eye on later. Tonight I will clean the tank with soap, peroxide and water and plan to snag some hydroguard this week at the store. I added Bud explosion to the nute recipe this week and will begin to decrease Part B Nutrients slowly over the course of the next two weeks. They are still a little shorter than I would like, but the good news is there is literally no more room to scrog so its all vertical growth from here on out. Hoping that they have a good stretch this week. if they could be between 65-70 cm by the end of flower week two I would be very pleased. All other conditions in the tent have been great.
