2nd week flower. Yellowing leaves.

MedicalMike420 · Mar 24, 2016

i switched the lights to 12/12 on March 11 and they are still under MH.
I'm feeding fox farms grandmaster(full line) in soil. I use just right lite formula 420 for my soil. Noticed this yesterday I havnt checked the runoff ph.
Any ideas what this is? Just a simple deficientcy and I just need to change my feeding or is is something more serious. I'm following the schedule and mixing at full strength.
I'm not seeing this on the other plants. (Strain: medicine man)

I'm growing medicine man the auto version 'rhino ryder' and it seems to be a very finicky plant, I have run into a few issues when it came to over feeding, I would lower your feeding ratio until you see it recover IMO. It worked for me atleast..
Good luck

This is her now

So could be over feeding? That's possible I wanted to do half strength but advanced recommended full. I'll just do water for a few days and see what happens. You saw similar signs when you over fed?

Also had a slight suspicion of some spider mites on clones but I really think it was mold. Would love spider mites do damage like this?

cindysid · Mar 24, 2016

That doesn't look like spider mite damage at all. IME spider mite damage is little white specks all over the top surface of the leaves and if you flip them over and look carefully you will see the mites.

I concur with Cindysid, you'll definitely know if you have spider mites. You'll see them buggers crawling all over your stuff.
Looks like a feeding/nut issue of some kind.
Maybe the attachment will help.

Yea, I had lots of problems from the start, but the whole thing was an experiment, now I wish i would have left it alone because its effecting the yield forsure.

I never grew an auto inside, and im at like week 11 and it looks like it needs another 3 more. We will see what happens.

Here's some more pics.. My critical kush is doing it with a couple leaves at the bottom it looks like but not as much.

Berrn1derrrn · Mar 24, 2016

They look pretty healthy.. what I did was flushed her, then hit her with 1/4 nutes imediatly after and didn't water again till the soil was completely dry. Try that, it should clear up your issue. Also I have been told by many expirianced growers to not use the recommended amounts of nutes....Less nutes, more feedings

Do you think it's a nitrogen deficiency?

Couldn't tell you, determining deficiencies isn't my specialty. I'd rather just say that then pretend I know the answer and lead you down the wrong path.

The yellowing, and twisted leaves are old leaves right? The new growth is a bit light but healthy just the same. The issue is a N deficiency. But, N is not absorbed or needed as much in flower as it is in veg. But you are in early flowering...how much Grow Big are you feeding? FF recommendation is 2tsp

I use advanced nutrients now. Havnt used FF since last grow

Burnt tips and curling up is from nute burn. Full strength from the beginning of flowering is too much

I guess you must have had a great hit before this typo ,where you say you are using the FF full line. Anyway, add some vegging nutes to your current mix and raise the N level a bit. But remember older leaves will die off with N issues when the plant reaches maturity.

If it's just a few leaves I wouldn't worry about it too much

$bkbbudz$ · Mar 24, 2016

Well, this is what I get for not reading a whole threads before replying. I just noticed you are using full strength nutes very early in flower so. as Jenny said, It also may be nute burn

Agreed to a point...if it is nute burn and is not dealt with...the whole plant will be affected and will not recover...loss of quantity and potency.

Maybe its related to me starting flowering nutes the day I switched my lights. Someone mentioned I shoul have waited. I'll have to check the ph
