Week 7 (2/21-2/27)
Day 43 (2/21)
They got watered this morning, about a half gallon each. I added in some Cal-Mag because there were some rusty spots starting up on some leaves again. I thought that using the Berkey water filter would help alleviate the need for the Cal-Mag, but it seems that it is still needed sometimes. I also added in some Mammoth P. I'm still struggling with the Roc's auto, she has diffuse color loss but is still hanging in there. Can definitely tell she is lagging behind now, the dos di dos and gorilla glue are starting to thicken up at the bud sites while the Roc's auto seems to have stalled a bit. The white widow is just doing her thing and taking her time.
Day 45 (2/23)
Well, I think I f'd around and they got lock out. After watering the other day, I looked more into it and realized that this is probably the case. Today I will run a bunch of water through them and try to get them back on track. When I give nutes, I will probably stay in the flower week 4 at 1/2 strength.
Day 46 (2/24)
So, I kind of flushed them all last night. Each got about 3 gallons of pH'd water ran through them. I'm really hoping it helps, but we will see.
Day 48 (2/26)
Gave them water with some nutes this morning. Each got a 1/2 gal of water, with Flower Week 5 nutes (soil a & b, bud xl, and top booster) at 25% strength. I went ahead and moved on to with the nutes because I was starting to worry about having low phosphorus. They seem to be on the up and up after the flush the other day
Might I suggest a fulvic/humic/seaweed supplement just a ml or two per gallon. It should help keep things soluble. And definitely check your ph pens calibration.
Good luck!
