modified cannabis leaf guide

[s00thsayer]

The "deficiency and abundance of fertilization elements" cannabis malady chart that is circulated is useful but it needed some changes in my opinion. So...here is a modified version with a bunch of changes...

Changed the layout
Added healthy leaf
Added calcium leafs
Added P abundance leaf
Added K abundance leaf
Modified N abundance leaf to show burned tips
Modified K deficiency progression leafs to be more accurate
Modified Mg deficiency progression leafs to be more accurate
Removed leafs that were inaccurate or not very useful

YESSS!!!! Excellent work, thank you so much. Really, very much appreciated, this is something I don't think I could have done well, but have mentioned needs the doing.

now we need a stem color chart

Love it,


only problem is many novice growers using competent off the shelf base nutrients start trying to add more of whatever they think is going "deficient" when they have zero fucking clue about adjusting/controlling their PH


and then they show their leaves online when they start yellowing, and all these forum warriors pat themselves on the back by guessing which yellow leaf it looks like on the chart

thank you so much, nice work!

I would also love a stem chart.

Wait, what - people misusing knowledge on the Internet? Has this been confirmed?

Amazing improvement for the chart.

thanks all. glad it looks useful! of course growers are still going to have to figure out why their plant has deficiencies...under fed, over fed, pH related, nutrient imbalance, or whatever. it would be easy to add stem color to the leaves but i don't know the stem color to go with each of these deficiencies, and i'm not sure how useful it would be in diagnosing nutrient probs....anyway, this is a start on improving the chart.

Next step is adding root rot, gnat and thrip infestation.

That looks like the worst leaf miner damage ever. LOL! WTH is that?

 

[nonsmokingcanna]

Any ideas? 24 inches from bottom of 1000 watt air HPS. Light? Heat? nutrients? damage from fimming? Only on a few places.Thanks

 

[nonsmokingcanna]

It is in a flower room of 20 plants, still have one last seal to complete this weekend, and then co2 will be operational. The open seal may have let a pest or two, but no sign of growing or infestation (yet) . Will take a few more pictures. Thanks

I think only one plant, treatment was a healthy does Neem. I use Neem every two weeks as a precaution of spider mites. I think a small leaf miner or two got in. In the high desert there also locus type -crickets occasionally.

 

[nonsmokingcanna]

Did a double check of all, still seems to be only one and the critters must have come in under the door seal ( soon to be sealed) not wanting to take chances with flowering soon I removed all I could see. will follow up with neem as precaution
