This grow I am using the full compliment of Fox Farms fertilizers. That is everything they suggest in their feeding schedule. They say you can fertilize UP TO twice a week. So what is enough? I have been doing it once a week. I would do it twice a week if i thought it would ad to the yield. Here are some pictures of the plants as they are today.https://photos.app.goo.gl/3AqWMBS5rPudNRmw6 . Notice the last two pictures and compare the plants to the plant on the left in the first picture. They should all be Purple Kush. The last two look to be sativa More than anything. The one on the left in the first picture had huge broad leaves on it before I pruned it. Just scratching my head on the different appearance. Before this thing turns into a poorly written book I’m going to bring it to an end.
Your plants look excellent Growmie and would suggest to keep doing what you’re doing…keep it simple and less is best.
Other than the trio what else, be careful adding supplements like PK boosters. Your typical base nutrients supply all that is needed. Would ask if you’re monitoring input PH and PPMs as well as the run off of these 2. FF nutrients are notoriously salt heavy and not feeding to liberal run off can lead to these salts accumulating in the root zone driving up the PPMs and tanking the PH 
Be sure to do the flushes when the ff nute schedule calls for it.
But wait…people here hate Fox Farms…i thought they were the wrost products ever!?!
Cleary I’m being sarcastic…your plants look fantastic! I used FF successfully for years, though i dialed their recommended dosages back a little…and i typically do so with any nute line. Ive never been able to get more than one feed in in a week if i’m alternating with phd water…they just dont dry out fast enough.
I use the ff trio with calmag.
I alternate my feedings.
Feed, water,feed,water, ect.
I did try the 2 feedings in a row and it was too much, burnt up some tips.
I am on auto pilot with theses nutes. But depents on size of your pots and how often you water. Sometimes you do get 2 feedings in a 7 day period. I stay on that weeks feeding sxchedule.
Your plants look good!!
I am watching the PH with every watering to include when adding nutes. Other than the basic three…Boomerang 5ml, Kangaroots 5ml, Micro brew 5ml, Wholly Mackeral 2.5 ml, Kelp me kelp you 5ml, Open Sesame 1.5 g. and Roots Organic elemental…all per gallon. I do this once a week. Other than that I just water about two more times a week.
Good news Bigb2…I did my first flush today. Used Sledge Hammer, Hope it makes a difference in the long run.
Thank you sir.
I’ve dialed it back as well. I finally figured out that less is better than to much.
I’m ashamed to say I have a Apera PC60 and I have never used it. Perhaps I will talk myself into using it on this grow. I will need to read how to go about it. I swear this growing thing has been a never ending learning process.
truer words have never been spoken!
