It's been a busy week, the girls are starting to get very demanding and needy of attention. Constant battles with ties and leaves. The girls are strong, too - I tie down branches by looping one end of garden tie around the branch, and then pinning the other end of the tie against the pot with a stake. But they are literally pulling the stakes up.
Had only done some light defoliating up until now, but with all the training, too much foliage was choking them up. Cleaned out the lower and inner parts of the plant as per the Mephisto strain guide.
Been pushing the nutes a little harder this week. Up to around 1.7, which is about as high as I'll go as I think they will start flowering any day now. When that happens, I will back off the A + B and bring in some Canna Boost. Can maybe increase a little once we get to mid-flower, but we will see.
I still haven't tried switching the auto pots back on yet. I'll be moving the grow downstairs once flowering starts proper, to a room with a built in dehumidifier - much better ambient environment for flowering. I will switch the auto pots on then I think.
For now, I've been maintaining a 4 x a day fertigation schedule, starting around 7am, then every 5 hours through until 10pm. They then have a 9 hour overnight period, with a 2 hour lights-off period in the early hours. My other 2 hours of" lights off" is made up of 4 x 30 min periods in the day when I am watering / draining run-off, which gives a total daily light schedule of 20 hours. I tend to increase the amount of run-off in relation to the EC. At low EC, I will usually water to around 10%, increasing up to around about 30-40% at the current feeding level. This equates to around about 3 liters of nutrient solution per plant being poured through the pots on a daily basis.
Despite the severe haircuts, the girls have been thriving and seem to be entering their pre-flower stretch. Plant on the right is slightly larger, with some better node spacing, but I'm happy with both plants. No definite pistils yet, but they will arrive any day I think. I've lowered the light to 15", although I'll probably be swapping it out this week and bring in the bigger flowering lights.
Happy days!
I have 2 plants in 15 liter auto pots. They have been in their final pots and being top fed for 2 weeks, which should be long enough to switch on, but I read that I should wait until the leaves are as wide as the pot. What do people think based on the current size?
Hey!
You need your root system to be developed enough that it makes it to solution.
Once your root system is pretty good you’ll start to notice pretty rapid growt.
You've mentioned she doubled in size so I’m thinking that's starting to happen.
It normally takes 15-20 days.
The leaves to the edge rule of thumb is good to follow.
I'd say your almost there, maybe another 2-4 days and go ahead and turn them on.
Good luck and happy growing!
White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?
Yes my friend, you have been running at the top level of ph for soiless grows so the 6.2 in the runoff is actually set for taking more p and k not nitrogen. Get your ph down to 6 or under in your runoff. Just feed at 5.5 until your ph runoff drops and things will get better. When you switch to flower, and you see flowers forming, start your girls at 700 ppm 1.4 ec and 6.2 ph for early flower, mid flower 6.3 ph and 1.6 ec and for late flower back down to 1.2 or 1.4 ec. Cheers
@Budbeast83, too right mate! Most has gone in for a cure, but I've taken some off the top for the Xmas hols. It's going down very well indeed :) Happy Christmas, and enjoy your harvest!
@Budbeast83, thanks man! Yeah, I think these were the smaller of the White Crack phenos. These were fimmed at beginning of week 4 with lots of LST. They took it well. Got very bushy though, and being tightly structured made it tricky to work with, but happy with the result.
Heard lots of good things about Mephisto, so had to give them a try! I have chopped these down now, they are currently drying, can't wait to have a taste. As they say, it's beginning to look a lot like Xmas :)
