My advice to new growers like yourself, is to take some time to start learning the cannabis plant and how the nutrients work.. What nutrients a canna plant needs, at what levels, and when.. Learn the needs, growth patterns, deficiencies, ect. Learn about when to water and when to feed (which are two different things).. Same with the medium and nutrient lines you are using.. Learn how they work together, how they interfere with each other ect..I hate to see you guys having so much trouble just trying to feed the plant correctly. I don't have all of the answers, but I promise you, that the plant does! It will show you exactly what nutrients it needs if/ when it needs it.. If you are overfeeding, under watering, if it's stressed, ect, the plant will show you. We have to learn how to read those signs. Mega crop has a heavy npk ratio.. If you are growing in soil, you may only need to actually feed the plant a few times (the plant will tell you).. If you are in hydro or coco, then you should be using their feed calculator to get the proper dosage. 5-12-26 is far too heavy for a seedling.. So it must be mathematically reduced to lower those ratios to fit each stage of growth. That's why they market MC as "customizable". Feed charts are "recommendations".. Not laws. And 99% of the time, these feed charts and nutrient lines, aren't designed for autos that veg for only a few weeks and spends most of its life in flower. That's a huge factor to consider in feeding and following feeding charts. That's why people recommend starting any nutrient line at half strength.. A little fyi, the term/word "crop" in gardening refers to grains, fruits, and veggies.. not flowers..
I want to see all of you succeed in every way that you are trying to! Dialing in MC seems to be an issue for many.. I just think all of these things (and more) needs to be considered when feeding or just following the feeding charts of any nutrient line. I think
@Mañ'O'Green has a handle on the feeding calculations, maybe he can provide some insight on lowering the dosages and ppms for different stages! I hope these issues get figured out, and want to help as much as possible!
