When this grow.was over....did you still like mix #3 the best?== Base Nutrient Change ==I'm at a crossroads with nutrients right now. I started off using off-the-shelf nutrients and had few problems. I'd get some tip burn occasionally before dialing it back. I started with Advanced Nutrients and they were OK, but way too expensive and too many products needed. I did several grows with Prescription Blend and loved them, really easy to use and beautiful plants. Remo worked out really well until it didn't. I fried one plant and scaled way back... to far back at first. Now I use my MC based nutrients all through flower. I've found it works great for the first 20-25 days. Then I start getting a few deficiencies, nothing too bad. I haven't harvested a healthy-looking auto in a while, though, as they fade fast toward the end. I feel that what I am using is on the low end of what is needed.
Although I have read some studies showing no need for increased P/K or decreased N in flower, how do I explain how all cannabis nutrient lines scaling up P/K in flower, especially weeks 4-6? Why would they recommend this if not needed? Does this explain why my plants are fading during this time?
Last weekend I entered Remo & PB into Hydrobuddy and calculated the recommended dosages of each for each stage of flower. Remo seems way too high, with 222N & 441K at the peak of flower! PB isn't too far from what I'm feeding now. A bit lower in N and higher in everything else, but not too far. I decided to use PB as my new targets.
My 'base' nutrients right now is MC Mix1. I'm still deciding between mix# 2 or 3. I like Mix# 2 for hydro because it has the Bud Explosion as the P/K boost. It's not too different from what I'm running now. Mix# 3 is really close to PB Wk1 and looks like a great flower base. It has Sweet Candy to bump up the P/K/Mg/S. I can scale up either one with Purpinator if needed. I have some I need to use up, and it's easy to measure and use.
KEY: MC=Megacrop 1-part, PB=Prescription Blend, MgN=Magnesium Nitrate, BE=Bud Explosion, MgS=Magnesium Sulfate (Epsom), SC=Sweet Candy, Purp=Purpinator.
Right now I'm leaning toward mix# 3 for the autos, especially since I'll be starting on day# 20 of flower. I'll mix some up and start Gaby on it tomorrow. She's coming into the end of the stretch and into the part of flower I usually start to have problems. It should be easy to spot any issues on her. Except for a few LST marks on a couple of leaves, she's still looking nearly flawless
I'd like to use Bud Explosion, 0-26-37, in flower. Green leaf says to use 1g, assuming on top of 5.5g MC. Thoughs?
It still looks like she could start flower any day, though. Her nodes are stacking and she's throwing pistils and trichomes everywhere. I'll keep up with the occasional snip and pinch to keep her cleaned up and slightly stressed. Flowers are coming any day now...
