Yellowing of new growth - older leaves edges are turning browny/orange

Yikes! Sulfur or iron deficiency?

Not common whatever you got going on.

Your pH is out of whack. Too high you will get iron deficiency. Too low Sulfur deficiency.

This is a total pull it out the ass guess, admittedly. But you got a major problem.

holy shit how did you let it get like that :O

i agree on sulfar or iron most likely sulfur . check your ph, what kinda soil, lights , nutes and water are oyu working with

pH going in = 6.5
300w LED
1.5m x 0.6m x 1.5m tent
2 clip on fans
Tap water 370ppm


This started to show after i fed some pH perfect sensi grow - i done 2ml per litre it says for plants with 3-4 sets of leaves - maybe they meant bigger sets of leaves? lol

Due to the edges turning the orange/browny colour, plus the iron looking deficiency probable nute lock out ?

Loopks like your Frying it with those ultra cool LEDS! RAISE THE LIGHT!

oh god BUDLEY i see everyones problem is there lights are too close because the last 2 threads i went to this was your advice 1st on an hid grow and now led..jesus man you must me a jack of all trades.

Sure thing bro. that 4" tall plant is so defecient it is white. Must be the nutes. Not the environment. Buy another bottle of wisdom from advanced.

I think it just needs more food, looks deficient in everything including love. Check the Ph of the soil too.

probable nute lock out ?

Yes because the soil is so crap the ph is way out and it has nothing in it. What is the medium?

root rot? try digging in with your finger a little and smell it , you'll know if its rotten
