Hello im new to this and only bought the grow big and tiger bloom originally. I now have purchased the big bloom because i guess i missed that its a big part of the schedule. Im not exactly following the schedule to a T anyways, erroring on the side of less nutrients. Also bought the Bush doctor cal mag. My question is do you mix the big bloom in with regular feeding or the flush in between feedings? The fox farms chart isnt clear on that. And from my own assumption the cal mag is more of a stand by nute…planning on only giving 2 feedings of that unless i see a deficiency. They are just over 5 weeks old and have been really taking off after a rough weeks 2 and 3. Ive fed them 4 times now with the grow big, 1/2 strength every other time because i have to water every 2 days with 2 gallon pots. And a pure water flush in between those feedings.
1st pic is 6 days ago with my first lst after topping the week before.
Your girls look nice and healthy. Here is a chart. It reads in weeks but i find that it is easier to follow once flowering starts since that can vary from plant to plant with autos. 1/2 dose is recommended
Be sure to check your pH of the runoff. Maintain between 6.3-6.8. 6.5 being the sweet spot. Also, when your ppms from your runoff drop below ~1000 then you know it’s time to feed again. Follow the flush schedule, easiest to perform using sledgehammer. Looking great thus far…
I havnt been regularly checking the run off ph 
. I did a slurry test when they weren’t doing so well and the ph was good. So with that knowledge and the help from a few people on here i determined i was underwatering. Thank you for the advice. Everyone who has responded to other questions i have had has been extremely helpful as well. This is a good community
Many different techniques for feeding cycles.
Your approach is a good one, lighter then they suggest and a feed water feed water schedule can be fool proof long as you get plenty of runoff on them water only days.
It’s basically a fresh start each time and effectively turning a soil grow into a drain to waste grow.
Long as theres no issues, I wouldn’t be worrying about runoff ph.
At the first sign of anything I would test runoff ppm to be sure they aren’t building up and if so maybe a good flush or just 2 water days between feedings.
As long as you’re going in at 6.5ph in the small containers watering frequently, it should stay pretty stable
