Nute Burn or deficiency?

Notice how some of the leaves are yellowing with brown on the tips (bottom right leaf is good example). I just transplanted this girl from soil to hempy about 4 or 5 days ago because she was looking like this. Since then I have been feeding once a day with FloraNova Grow at 1/2 strength. I am going to flush with plain water today and then go back to feeding tomorrow. Is this some kind of deficiency or a burn. This is my first time doing anything hydro so it freaks me out to be totally responsible for the nutrients. I am new and have harvested a couple of plants using MG moisture Control and I never had to feed them nutes. By the way, the leaves overall are looking better (no wilting or twisting) however the yellow with brown tips has gotten worse since the transplant.

In hydro? What is the concentration of feed in the pond?

That looks like too much feed.

It is in hydro now, but this problem was prevalent while the plant was in soil. It was doing great, then in a matter of a day or two began to look like this. I was going to just get rid of the plant to make room, but I decided to transplant to a hempy bucket and began feeding with General Hydro FloraNova Grow at 400 ppm (just below half strength).

Well, you are test pilot, taking water roots and putting them in a medium. :)

GH guidelines are incorrect, imo. 400 is too much of that plant size. Go to 200 and wait? She us severely over fed, seems to me.

400 is what I use for a healthy 2 ft tall plant. She needs a rest, I think.

Sounds like a plan to me. I will flush today then back off on the nutes for a while.

Yeah, I have recovered nicely myself with that. I was over driving the feed and too much water on a pair of Skywalker.

When they finally struggle up to a foot tall, I could see they were right on the edge of stalled. So, I dropped to 200 instead of 300 usual for me at 1 ft tall, and dang, they woke up after a few weeks and pushed open the over watered stem pinch and will actually yield in their month for yield and not just shoot a blank for me that month. Now they are 2 feet tall when they should be 3 ft tall. But, they are very healthy, and are stretching well in Bloom.

I have a Doer-ism for this. This plant is so hardy it really takes a clever human to screw it up. :)

Check your PH. Two different games between hydro and hemp or soil. As Doer mentioned, 400 is a lot for a small plant especially if fed every day. Do a flush with a very light nute solution, and don't feed again until you see improvement. Peace

Thanks for the input guys. I appreciate it and will let you know how it turns out. As far as PH, I have read that a lot of people don't even worry about PH with hempy. I Ann struggling with whether or not to worry about it.

Thanks for this. :)

Just an update. I backed off on the nutes and watering frequency and she has exploded! Everything is nice and green. She is in flower now and looking great. I'll try to post a pic tomorrow. I just wanted to say thanks for the help and let you guys know how it was turning out.

I found that pH can be a problem, in hydro. But, in Hydro I really got to see something worthwhile, so I'm glad I did it.

I had it instrumented as an experiment. I had 24x7 logging of pH and PPM going for a year. Good operation, only the subjects died in groves. :)

IAC, I saw swings around an average, like I could not believe.

The day/night cycle show big changes week after week.

Week over week change accelerates then slows again. But always the day/night cycling, for mainly the pH.

So, in hempy, or like me, top feed/bottom drain the root zones are much more stable. And I made sure my feeding formula was pH correct. My RO is right at 6.5. And I measured bucket after bucket until I could balance the 3 things I use for feed, to a good pH.

Cal/Mag and Silica Blast, seem to balance, in a certain proportion. And the right amount of that combo, will balance the Sea Grow and the RO.

So, once I standardized the Feed, I don't need to measure pH.

I do measure PPM back in the reservoirs. I can tell at a glance when the res needs water. The PPM goes up.

Measuring pH is expensive. I have great deal going on 10 ruined pH probes.

Free. :)
