I’m anywhere from a few days to a week away from wrapping up my first veg cycle (6 weeks) with Megacrop, and I have to say, I’ve been pretty impressed with it so far. Using water with an EC of 0.28 I’m currently at 4g/gal of MC and 1g/gal of epsom salt, now feeding twice a day to 10% runoff. The epsom is added in because I had mag deficiencies earlier in veg, which went away after adding the epsom. It’s been creeping back up, so i think I am going to up the epsom to 1.5g/gal for the rest of veg and see if that gets rid of it before flipping. I plan on bumping up the MC to 5g/gal once I flip, but where I would like to hear everyone’s advice, is on what to do with my base dosage as I add my PK booster (I’ll be using GLN’s new Sweet Candy, NPK of 0-17-28, unless it causes issues in my res then I would be using Bud Explosion in it’s place. I’ve seen pretty mixed opinions, some saying to lower the MC dosage as you increase your PK, meaning I’d drop to 4g of MC when I start adding in 1g of Sweet Candy. I plan on raising the PK gradually to 2g/gallon unless I start to see issues, meaning I’d be at 3g/gal of MC and 2g of SC from week 5-8. The other school of thought is to leave the MC at 5g/gal and just add in PK to that as I progress through Bloom. I’m not sure of the ppm of the new Sweet Candy, but I will find that out for sure before I start using it. With my water, 5g/gal of MC, and 1g of epsom, my PPM comes out to about 890, or an EC of 1.78. I am leaning towards dropping the MC as I increase the PK for two reasons, one being the high nitrogen levels and the other simply being I typically don’t go over ~800 ppm.
What do you guys think? I did see a post earlier where someone did a comparison where with one plant, they left the MC at 5g and raised the Bud Explosion to 1.5g, and another plant they lowered the MC to 3.5g with the 1.5 of Bud Explosion, and that user reported higher yields and more flavor with the lower dose of MC. I cant find the post now though and cant recall who it was that posted it. Have any of you had the same experience? What do you prefer to do, preferably those growing in coco under full-spectrum white LEDs, but still would love to hear from others as well.
