Many claimed that any problems with our plants could simply be solved by increasing the strength of our nutrient solutions. I remember back when you said 'feed, feed, feed' regarding Mega Crop. I was doing the same. I kept bumping up the strength until I reached 6.5gm/US gal. I think you were the first to walk back that mantra.Not every plant is going to be able to take 6g even at its peak in growth, and certainly not for the full amount of time it takes to complete the flowering process.
You can use my current grow as an example of what happens when a plant is fed with too strong a concentration of Mega Crop for an extended period of time. My lower leaves turned a shiny dark green, typical of a nitrogen excess. The tops of my plants took a while to catch up, but they started showing the effects of excessive phosphorous and potassium. The end result was a harvest that barely reached 1/2 of what I should have had. The buds were all light and larfy.
I have one plant left in my grow. I dropped the strength from 6.5gm/US gal to 5gm/US gal. The plant is slowly recovering. I don't expect it to reach its full potential.
I went back this week and re-read the instructions on Greenleaf Nutrient's website. I should have done this much sooner. It echos what Emilya is saying, or is it that Emily is echoing the website? Anyway, the strength given there are suggestions to use as a start. They then say:
Step 1 – Dialing In Nitrogen levels through MEGA CROP dosage by monitor your plants coloring:
- Pay close attention to the green coloring of your plants leaves. Nitrogen levels in MEGA CROP are strongly related to how green your plants leaves will appear
- If your plant leaves are light green or yellow, then increase your dosage of MEGA CROP to boost Nitrogen levels and increase green color
- If your plant leaves are too dark green and/or have burned tips, then scale back your MEGA CROP dosage to reduce the nitrogen.
- Your goal is to have the plants coloring to be a strong healthy green without burning, and you control this by increasing or decreasing the MEGA CROP dosage. If you are a new grower and not sure what color your plants should be at, browse the internet for pictures of healthy plants of your same type. You should make dosage changes for the first time in small amounts, for example changes of 10-20% increase or decrease only, and then waiting 2-3 weeks to monitor plant response after each change. Since the plant has to take time to uptake nutrients and process them, it may take 2-3 weeks to notice the results of the changes you made.
My next grow will get Mega Crop as directed. I'm not ready for SK or BE, and will probably add them in later grows once I get the basic Mega Crop dialed in.
Isn't reading the plants, and responding to their needs what we have done with any grow? What in the world made me think Mega Crop was any different in that respect? Lesson learned!
