Guide to Nutrient Deficiency or Toxicity

roachfinder · Apr 21, 2016

Plant looks like is has a boron or sulfer deficiency....but that plant is not spindly. Then I was thinking too much calcium.... I just threw the coco coir in the cups. Its only one plant thou out of 8. Last night I noticed the edges of the 2 fan leaves were Brown.......today I can see purple and going on more of the leaf..... These are almost 2 week old seedlings...but they are small. The off colored spots are a purple color

What causes purple leaves from the tips and edges...progressing inward.

EireAran420 · Apr 25, 2016

My seedlings are about 10days old. One of my babies leaves are totally white. You know how the seedlings look after they just pop out of the ground and the stalk/stem is still white? Well my babys first set of leaves are green accept for one it is totally white and I have never seen this happen.mabye over watering with a low pH? I had 6 diffent stains 5 beans each and I fed them all with the same water. I think this one is just mutated or something what you think? Will I give her another week? if I see no change will I just toss her out?

That is weird to just have one leaf white. isnt that iron deficiency tho? If you can test your soil ph that would check one off the list. I usually nvr worry about it bc i have ph perfect advanced nutrients. i dont think it could be light burn if its just one leaf.....what lights are you using? I think i had my led light too close myself.....and deficiency.

My temp gets up to about 80 sometimes and drops to about 71 at night. so your saying even though its not "cold", the fluctuation can mess with the plant?

I am using a 250watt cfl just to start them off. The pH should be fine. I ordered a new pH tester on eBay should be here in the next few days. I checked on them today. The leaf is still a pure white.dunno I'll leave it to see what happens. My leaves where turning purple because of the cold . but I have read that a drop of temp below 10 degrees below the day time temp, during the (night),can make the plant produce more ( chrophyll) chrophyll is the chemical that changes the colour in plant different strain's chrophll can produce many different colours and at different stages . I'm not 100% percent sure if that the correct spelling Chrophyll chrophylln .??

Id like to see a pic of this. Purple could be lots of things, phosphorus definciency, or it could be the strain. post a pic and lets see

I run my plants at around 80. 70-80 degrees is typical. How do you think Mexican and African Sativa and Middle-Eastern and Himalayan weed grows? 23-27? Degrees celsius is optimum range.

Am I wrong or does your meter say your pH is at the low 5 range?

Holy fuck, dude, use some pH up and possibly some cal-mag or epsom salt diluted in water. 3.5? Jesus..

Hey, you're right. He's like, 5.5. It only needs a little bit of pH up or something. Should be alright.

Looks either like you need phosphorus and potassium, or you're just really close to harvest.

All 8 of my plants turned purple. There's 3 different strains...1 is unknown and I have cookie monster and original sour diesel. After not growing almost at all I cut some of the leaves off. I am having trouble up loading a photo but I'll figure it out soon. Thanks for the reply

Oh hey.....if you go to the top of this page you'll see one of the plants a couple weeks ago. As u can see it has a couple more layers now but overall way too small than it should be.......but that pic is the start of the purple. The one I just posted, I just took. These plants are like 34 days old. I've nvr had it this bad. ):
