So I have been growing hydroponically now for almost six years now with three plants in a 40L seedling tank, and three mature plants in my 85L tank. I dropped a Purple Punch, Skittlez, and Godfather on 8/4 and they took off like a rocket. I planted them in clay pellets on 8/10, and moved them to the big tank on 9/10. I like to flip to flower when they reach about 50cm tall to account for the stretch and these were very close. I attached pictures when they were about 28 days old and about 40cm tall.
After moving them to the big tank, I mixed up nutrients according to GH 9 part Late Veg Feed Chart found on line. I like to use additives which get me in trouble a lot, and this time was no exception. To complicate matters, I fogot the list of nutrients in the other room. I use a walker and wheelchair to get around and that paper was a bridge too far, so I added my nutrients from memory. How does that saying go? Ignorance leads to Arrogance, leads to stupidity. Well, I know where I am now on the scale. Here’s a picture the day I moved them.
So I tried making nutrient additions over three days, but Purple Punch was suffering, so I dumped the Rez and that fixed the problem.
Here’s where I struggle the most when toxicity, deficiency issues occur. I can’t for the life of me determine the problem from a picture. I simply don’t possess that skill so many on this site have. So to try and make up for my inability, I figured I would try to incorporate the " Nutrient Relationship Chart" I downloaded off this site awhile back. In the next slide I listed the actual Nutrient content in milligrams I calculated from the products listed on the left side. I compared the results to the nominal “target” values calculated from the GH Late Veg 9 Part Feed Charts and found the difference. Target values for each nutrient are calculated from the potassium content in my nutrient solution. General Hydroponics agreed with my calculations, so that has already been verified.
I displayed the difference of each in the Nutrient Relationship chart and wrote my assessment on the bottom of the page based on antagonism, stimulation AND NOT THE PICTURES.
So what I am asking is for the very knowledgeable people here to look at the pictures in the center of the page and tell me what the issues REALLY are.
Thanks in advance and have a wonderful day!
