Wilting...what is causing this

[artsychick79]

Some of the leaves are wilting and dying. Most of them are from the bottom of the plant. The rest of the plant looks strong and green and the stems aren't dried out. It is getting time to start flowering the plant. Is it doing that because I haven't started flowering or is it just a part of growing or is there a problem? Here is a pic of the leaves that I took from the plant. I don't know what to do. Help?

How much light do the bottom fans get? It could be lack of light if the rest look healthy.

This looks like nute burn. Some of my plants have done that, but they grew new leaves. A good flush never hurts. After a while, while growing in soil, the water evaporates and the leftover nutes that havent been absorbed by the plant dry out and become salt crystals that are concentrated. The plant's roots start sucking up concentrated nutes and the whole plant sufferers, starting with the leaves first.
Lower and fan leaves will start to yellow and die during flowering because the plant is using most of its resources to grow flowers. If you build your plants up during veg to be able to handle high doses of N, the leaves will get very dark green, but use that stored N to keep the fan leaves alive. Your plant can still use all the nutes you gave it during veg, but at this stage it uses more K than N, but it still needs N.

Check this out. These should be remembered by every grower..
Mobile nutrients re-translocate within a plant: they move to the specific part of the plant where they are needed and cause OLDER LEAVES TO SHOW DEFICIENCIES FIRST. Nitrogen, Phosphorus, Potassium, Magnesium, and zinc are all mobile nutrients.
Immobile nutrients stay deposited in their original destination and cause NEW- YOUNG LEAVES TO SHOW DEFICIENCIES FIRST. Calcium, Boron, Chlorine, Cobalt, Copper, Iron, Manganese, Molybdenum, Selenium, Silicon, and sulfur are all immobile nutrients.

And by the looks and age of your plants I would say you have a problem in your MOBILE NUTRIENTS. Try to add some magnesium. Thats were I would start. If your getting rusty brown then all over brown leafs this is your problem... Hope this helps you to get were you need to be man. Take a puff for me if it works.

Bro, I don't know where you came from, but great information. I had a general understanding of this, but you explained it very well. You should stick around here on RIU it sounds like you have some good info to share. This isn't my thread, but I do appreciate the lesson.

Thanks everyone for the info. As long as the rest the plant is healthy and its not but a few leaves then I'm not going to worry. Just wanted to ask in case I had bigger problems. It is growing healthy leaves and the rest of it is strong so I'm not going to worry too much about it. If it gets worse then I'll come back and ask more. One more thing. Can I just start them on the blooming nutes or do I need to flush everything first then do it? I'm new so I don't know what to do on that. Help?

i agree with 30years looks like it could be mag def or salt build up in soil try adding epson salt 1 table spoon per gallon this helped when mine did the same thing. gl happy growing

Well i think the best thing is to flush. Then make a new batch of nutes with ur bloom. I personaly flush 1x week. and change my nutes 1x week, while i scrub and clean everything. I LIKE TO KEEP IT CLEAN AND MEAN!!!!!!!!!
