Mad props to all the effort put into this one J Fresh. I just posted a thread in the infirmary w some pics and I didnt really get any help, so this thread definitely informed me of a bunch of things that i needed to be educated on.

Thanks again

-Stay Grateful-

Wow, a picture guide is what I need most! I'm sure most people will agree that this is much more helpful than some of the picture tutorials and graphs out there. They dont' really work for me.

So props for that.

I have a question. I'm having a deficiency that I posted here: https://www.icmag.com/ic/showthread.php?t=231093

My leaves look like they have the exact same issue as these, except mine are still in veg. I can't seem to tell which Nutrient Deficiency this is listed under on your guide. Is it Manganese, Zinc, or Iron?



Those have all my symptoms in the leaves, bleached between veins, downward/sidewards curl, etc. Can you help me out?

Here's mine:


I noticed that this picture was next to them but it doesn't seem to be displaying the same issue:


Thanks bro, your guide was top notch.

^^^my first thought would be cold root zone temps, or overwatering/lack of D.O.(dissolved oxygen), or a possible iron or zinc def(your intervienal chlorisis starts at the inner leaf and moves out and also is located near the top is more yelow/pale growth)....

check your runoff to see where you ph and ec stands

Thanks Joe,... trying to figure out nute deficiencies is one of the hardest symptoms to diagnoise. There needs to be a lot more updated pics because the deficiencies over-lap so much.

Maiks look like nitrogen on the first pics, to zinc on his last pic with those tip ends turning yellow. Could be lack of calcium too? (That's from SeaMaidens chart, which was compiled from George Cervantes new Indoor Horticulture book) Maik needs to provide more details.

I really liking all the extra pics, I can't tell you how many hits I attributed to the other sick plants thread, it's nice to have another. Thank you for all your hard work in putting this together, I know it will be a help for me and I am sure for many other as well!

I can't seem to find remedy for this: plant leaves (new) are curling tightly into a shape like a conch shell. I've searched my grow book (Jorge Cervantes) and searched here. Don't have a clue what's causing this. It's a Blue Dream in veg...anyone have any ideas?
