Whats the deal with ZINC????

[215zealot]

So we checked our nutes, we are using General Hydroponics Lucas Formula, and we noticed that our plants arent getting any ZINC. According to our grow bible, it says plants need zinc, however too much zinc can actually kill your plant.


Our kush plants are showing serious signs of deficiency, etc, pictures are on my other thread.

WHat are the best kinds of Zinc to get? Are there soluble ones we can buy at any hydro shop?

If you are feeding general hydroponics flora series using the Lucus formula then i can gaurantee that your plants have all the zinc they need.

I looked at your other post and Zinc is not the problem. What is your solutions PPM/TDS? and as others have asked you, how close is your bulb?

I am not really even sure how you arrived at a Zinc def?

Well we use a grow bible from Jorge Cervantes and my roomate thought so, also we checked all the nutes on our GH bottles and no zinc. Also, on the Icmag forums i posted a thread and one of the members mentioned zinc deficiency.

However i am pretty sure its a PH problem so we are flushing with 5.8 right now. It might be a combination of PH being too high, zinc deficiency, and these god darn fungus knats.

The picture I posted came from Icmag, here is a picture of light burn, from Icmag but I guess your convinced its not that.

If you are using GH Flora Micro there is zinc in it.
