Is this nute burn or a combination of things?

I bought cal-mag last week trying to clear it up. Not sure what is causing it. Using FoxFarm trio in soil with 5 gallon grow bags. Been flowering for around a month or so. I have a crappy PH/Moisture probe. It shows around 7 just like my water. It was only affecting the front three now it is on the top of my big one. They were watered last Friday afternoon before I left for the weekend. Straight water no nutes. Any suggestions?

most likely a nute deficiency if your ph is at 7 and you obviously dont over water. i would go to the nutrient deficiency chart and try to see which deficiency looks closest to your crops. to me it seems to look like a Phosphorus deficiency but you should take a look at it yourself. anyway if that is the problem just get a nute high in phosphorus and feed those plants.

looks like bugs to me.
LOL, no way. These plants are totally fried. I use the FF 'trio' but only in small doses. The grow big is especially potent even though the npk is low compared to petro-chem fertilizers.

Sorry to say, you won't be able to reverse this, you'll have to watch the bud growth, at this point, there will come a time when the bud will reach 'the best its gonna get' and after that it will start to deteriorate and lose mass. When the small little fan leaves in the buds start browning and are able to be pulled out, time to take it down, which based on those photos, is going to be in about two weeks, no matter how big or done the buds look.

In the future, make sure you mix your nutes ahead of time, balance the ph, let it sit a few days, and retest it.

Do you think flushing might help?

Do you do hydro or soil? I use the Foxfarm trio in soil and my plants lovve it

Not really. When they look like that, they're toast. That thing will soon start looking like a maple tree in october. I'm not making fun, I just know this because I've done the same thing in the past with FF.

Mine love it too, and I do soil. But people don't usually know how to apply nutes, if you just dump it in your water and serve, they're going to react poorly, was my point.

And as I've mentioned in previous posts, I like to give them a good dose of 20 20 20 water soluable, early in veg, and then only periodically use FF, no strict schedule, just tuned into my particular strain.

flushing could help, 7 is too high for ph try to bring it down to 6 -6.5. does look like nute burn but you might have ph problems as well especially since your tester dosent seem to accurate

I am going to pickup some Clearex after work today (unless you guys think there is something better to use for my situation?). Can someone give me the run down on how to properly leach/flush? I am using 5 gallon grow bags in soil. Also what should my follow up watering / nute schedule be? I thought I was doing good following that damn chart that came with the FoxFarm nutes. Man was I ever wrong.

I have been doing a little research and looked at a couple of videos. Do I need to use the Clearex or should I flush them with tap water? I seen a few videos of people just using water straight out the tap. All my water sits for a few days with a couple of air stones in it.

I have 5 gallon grow bags so should I run 10 gallons through the soil to flush each of them? I only have about 7 gallons of water that has been sitting out.

Should I flush with tap water then use my good PH'ed water to give a light feeding after the flush or should I wait a few days to add nutes?

Well I flushed one of the plants last night with 9 gallons of tap water. I then let it sit for an hour or so and added a gallon of ph'ed water with 1 teaspon of the grow big, tiger bloom, and a little over a teaspoon of big bloom, instead of 2 teaspoons and 1 table for the tiger bloom. Also put a teaspoon of cal-mag in.

I know the pictures I uploaded looked pretty bad but when I got home last night the plants overall are not that bad. The one with the burnt leaves near the cola is green everywhere else except for a couple stray fan leaves. The other plants are not quite as big but they also have lots of green in most places. I took pictures of just the bad areas, and I think the HPS light makes it look worse. At least I hope that is the case.

I will see how she took to the flush then start doing the others if it helped. Anything in particular to look for before I flush the rest of them? It took quite a while to do 9 gallons in the grow bag. I had to add fairly slowly otherwise it would pool up to much at the top of the bag.

Yo, these plants are screwed you need to flush with a flush compound prefereabbly the one in the nutrient programme you are following. Then introduce sulfur to the plants which will trick them to think they are dying and force them to produce there bud imediatley and finish the grow. A product called Ripen is available from GHE to do this. Then kneel down in your grow room pray to God and thank him that you got any bud at all!!! Move on and learn every one does it at one point! Peace

Not what I wanted to hear! Sometimes the truth hurts. Does FoxFarm even make a flush? I was going to get some Clearex but went with straight water instead. Maybe I should pick some up on the way home.

Everyone else feel the same about this?

Many people think that water flushes out the nutes in a plant, which to a very small amount it does but the flushing compound available actually have chemicals that breakdown the nute build-up aka salts that have built up in the plnt over time. Imagine it as a de-scaler for a kettle you can rinse it out loads with water and that will do something but using a de-scaler chemical will get rid of a lot more. Any flush is better than none to be honest the only reason I say use you nute one is because they obviously know exactley what nute compounds they use and thereore can make the flush to remove these specific salts. Ripen is a god send when things go tits up it allows you to get something actually useable and doesn't pro-long the agony. God luck

How accurate is your ph meter?
It is a piece of shit analog. Those things should be pulled off the shelf. I have bought two different ones and they are shit. Only the moister meter works at all. I am going to buy a digital one on the way home tonight.

The local hydro shop has the Milwaukee PH-600 digital meter for about $35. Anyone have any experience with this meter? I know you can get it cheaper online but I need one now.

Do think that it could be heat stress on this one? We had the air off for the last week or so and I noticed that the temps at the top of the canopy are reaching as high as 96 and down in the middle it is topping out around 80. I am going to get a clip fan tomorrow to try and move some of the heat up and out the top.
