Today my leaves are turning yellow and are stripped and blotchy. It's the second run this has happened when I moved them from the veg tint to the flower tent.

I notice my runoff smells soured.

I use Maxibloom in perlite and vermiculite.

Help!

Less nutes and give them time to reveg. I can see three clawed leaves. That a late clone right, or a reveg right?

If all you're using for the base is perlite and vermiculite, you have to be careful how much fert you give because those materials don't have nutrients in them. You have yellowing leaf tips like over fert, but I don't know for sure that's your problem. what is the ppm you're using? How often do you feed? Is this like a dwc grow with water constantly moving or being bubbled?

Tbh looks like it could be a Mg def, I’ve had that a few weeks after moving to flower, I added Epsom salt for a few feeds and it’s fixed itself. There is a little tad of nute burn but that is not causing the light colour which will eventually turn yellow.

When you change from veg to bloom is ther a humidity change as well?

Also its too hard to say its nute burn without knowing the feed rate

If it smells sour id be pulling the plants root ball out of the pot to have a looksy.

I have some hunches but more info is needed

If it was nute burn he would have darker green leaves imo.

Something eles like a root issue if it stinks.
Root problems can make the top side of the plant go to hell fast :)

Dude the nute burn is on the tips of the leaves look closer, the very tips are discoloured, that Is nute burn! The light colour of the whole leaf looks like Mg (been there) the burn isn’t the problem it seems to be lack of Magnesium imo.

Well id be willing to bet it aint nitrogen .

How can you assume nute burn when he hasnt givien any information

But im no expert only doing this for 15 years :)

Since hes only feeding maxibloom id say he has a nitrogen deficiency

And possibly a lockout which is causeing the purple veins.

The tips could be burned off for a few different reasons

Could be a nute burn like you say mabey from to much p or k. But not n

Plus with sour smells i bet dollars his roots aint white and fuzzy right now :)

If you want to prove it to your self cut the tips of a rootball off from a clone and whatch as those tips turn crispy :)

I know i have :)

root health is directly proportional to top plant health and vise versa. Hurt the roots hurt the top plant as well :)

Nitrogen burn/tox you get the claw and very dark leaves, this be the opposite, everyone’s entitled to their opinion, where does the guy say he’s only feeding maxibloom? And depending what company the maxibloom is from it will contain some nitrogen, it comes down to what he fed in veg and wether that had enough N for the plant at that time as that tends to carry into flower. Like I said I had the same thing and a few small doses of Epsom salt worked wonders, didn’t lose all the leaves affected and new growth was healthy again.

Have all leaves turned the lime green colour or a select few? Lower? Higher? Mid? Need a little more info really to judge properly.
