ElDuro started grow question 3 years ago
2 of the very bottom leaves yellowed and fell, and 2 other started to show yellow parts, It seems to have stopped now. Wondering if it's due to the high heat and very dry air, or if it's nutrient related. Thanks!

@ElDuro Looking at the larger picture with the entire plant its pretty clear this deficiency is ONLY on the bottom of the plant making it an mobile nutrient deficiency. Typically With chlorosis(yellowing) caused on mobile nutrients(bottom effected first) we look at Nitrogen because its the number 1 deficiency that causes this style of yellowing. To resolve this issue simply increase the N in your feed and you should be good to go I hope that helps! :sunglasses:

Honestly my friend, the answer is very simple. When Cannabis goes into flowering the plant does what it must to optimize the production of it's fruit I.E. the buds. Sometimes the plant will signify that it doesn't need areas of the plant by slowly stopping feeding them nutrients. If this were a nutrients issue I believe that you would see an overall progression of discoloration gravitating from the bottom of the plant upwards. It's just two leaves so that leaves me to analyze that they plant just isn't happy with having leaves on itself that aren't receiving as much light as the other areas of the plant. Trim the lower leaves off of this beautiful girl and do some light defoliation. Then flush the plant with some distilled water and then lightly feed her a good regiment of your nutrients and I don't believe you should have any other issues my friend. Cheers.

Hi @ElDuro! Not enough Nitrogen during the pre-flowering stretch made this happen. It has stopped because the stretch has ended and the plant doesn't need Nitrogen anymore (just some P+K boosters for the buds to fatten up). Happy growing! :facepunch:

Hello ! It is a nitrogen deficiency as it spread from the bottom to the top , your next feeding with bat guano will probably sort your issue :v::skin-tone-3::grin:

Hey ElDuro, it's pretty standard nitrogen deficiency check this for more info hope this helps ! :rocket:

It's normal at this point, the stretch needs lots of nitrogen, the lower yellowing is a sign of early nitrogen deficiency. Just give it some grow nutes and you'll be fine.
