Can anyone recognize this leaf problem?
Dirt grow
400 watt MH/HPS
Temp 89f-76 on tops
room temp 76-80
Tecnaflora starter kit nutes.
Water-water-feed
water PH 6.4-7
Yeast Co2
I have 2 strains and the one with the yellowing is God bud but not the white widow.
I have been flushing for 4 days and no improvement.I also added a tad of Epsom salt for Mg 2 weeks into flower
Plants in week 5 of flower
Problem didn't stare until 2 weeks into flower.doesn't seem to be affecting bottom leaves that are shaded.

I'd say you have a nute problem on your hands bro. How much and how often are you giving them nutes?

I have to ask what strain? and being so many weeks into flowering that they are finishing up their life cycle . just my opion

Ok. I think you've got nute lock, because that is a more common problem. Here's what I would try. Since youv'e been flushing them for five days, I would say that you probably got all the excess nutes out of there.

Now before you feed again, look at your nutes and see what all is in there, (I'm not familiar with technaflora), and check and see how much of the "miracle 5",( the five nutes that makes up miracle grow), nitrogen, phosphate, iron, mangnisum, and zinc. Also see if it contains potasium. Make sure that all of them are in there and if they're not, add to the soil later. Banana peels work great for potasium, a very small amount of human hair will give off a lot of nitrogen, epsom salt fof magnisum, ect.

Then, give your plants only about a quarter of the recomended dose on the nutes. Remember you can always add more nutes a lot easier and quicker than you can trying to take them out. Wait and see how your plant responds. Don't look at the yellowed leaves, look for other leaves yellowing. You could take pictures of them everyday and compare them. Keep giving them about a quarter dose of nutes, while gradulally increasing to 1/3. Remember this also means time too. Don't feed them so freqeuntly, or even your reduced feed will cause nute lock.

Keep a very strict eye on your ph. Ph balance is another common mistake made during soil grows. It could be that your soil is gettting slightly too acidic. Be careful with it.

You might want to try different nutes also. Remeber that when your plants start flowering, their nute needs change.

During flowering phase of the plant's life you need to provide your plants with a higher ratio of phosphorus in order to induce and support developing flowers, as they are the bud forming sites and their number has direct influence on yield. Use phosphorus alone or fertilizer with higher ratio of phosphorus, like 10 30 10 NPK to ensure excellent and rich budding. As time goes on the buds will get bigger and bigger and they will use more and more fertilizer from what you supply them. But becareful not give them too much.

Secondary nutrients for your plant are calcium, sulfur, and magnesium. They ensure intensive photosynthesis takes place, allowing strong growth and stable development. There are also trace minerals that the plant needs: boron, copper, molybdenum, zinc, iron and manganese. Only minimal amount of those are needed, but they are essential to the overall well being of your plants. All these nutrients work together to maintain healthy plant development. Plants will grow poorly, stop or die in case of deficiency of any one of these nutrients.

Probably the most important thing to do is to remain calm and not panic. When you panic, you only make things worse.

It also just might be they're time. I've never worked with god bud so I don't know how fast it finnishes, but I'd say it's got to be faster than widow.

So try all of that and see if it helps. If it doesn't just comeback and we'll get it fixed. Good luck bro.

Water water feed. One or the other once a day if needed. It gets to be more the later it is in growing.Once daily water or feed.I haven't fed for 4 days trying to flush and flush increase it is too much nutes for that strain (God Bud)

I havent a way to check soil PH but the water I use is from a controled source and kept at 6.4-7 is that about what the soil would be or do I NEED a soil PH test kit? Thanks alot for the advise. Want to share Pic's?

You might want to go pick up some ph strips from a local pool and spa shop, or maybe a farming supply store, or I'm sure you probably get one fairly cheap online.

But yeah, the nutes will change the ph, usually making it more acidic, burning the roots and causing the plants not to be able to absorb the nutes or water, slowly killing them.

You should only be feeding them about once every 4 days. The other 3 days water them moderatley, making sure not to over water them.

I would like to share pics, but I don't have any.

Anyways, glad I could help and good luck.:peace:
