Nitrogen Claw

[JacquesWebsterJr]

Hello,

First grow; using 300W Galaxyhydro with Fox Farm Soil. Ph is 7
Looks as if my blue dream is getting early signs of nitrogen toxicity but I don't want to flush if I don't have to. She has some yellowing on lower leaves and a slight claw. My autoflower is currently flowering and has shiny leaves with some clawing also. Any ideas? Pictures shown below.

Your plant needs more nitrogen. And it wouldn't hurt to give it a little extra mag.
Which fox farm soil are you using? Ocean Forest? A lot of people add a cup of dolomite & extra perlite to ocean forest.
I've had good luck using it straight out of the bag but always have to add magnesium after a few weeks.

i doubt it's n toxicity, many things can cause slight clawing like watt you've got there, high heat, humidity, etc..

More nitrogen? I am using ocean forest and have been using small amounts of big bloom until about a week ago. Thanks for the help. Should I use more light maybe?

Ocean forest won't carry your plant through flower. Hell it won't carry it through veg unless you repot frequently.
That soil is made to be used with the fox farms "trio": Grow big, Tiger Bloom, and Big Bloom.
Big bloom is probably the best product of the three, but it doesn't provide much NPK.
In other words, you're going to have to feed it.
Since it's your first grow, I'd go with something like DynaGro Foliage Pro. It is a complete one part nute that you can use all the way through flower. DG also makes a good silica supplement called Protekt, which I highly recommend.
Just follow directions on the bottles & you'll do fine.
Both are very affordable too.

Would it be too late to continue fox farm schedule? I am purchasing DynaGro but I already have the trio. And also, if I am ending up using DynaGro, what is the supplement Protekt for? Again thanks for all the answers.

Also thinking about adding more light. I have another 300W galaxyhydro unused. Would 600 Watts in a 24x72 grow tent with only three plants be too much?

You've only got 12 sq feet, but 600w probably won't hurt em. Are they dimmable like an electronic ballast?
Also, If you add more light, your plants will need more food.

They don't dim. I just ordered the DynaGro. Should I use the fox farm trio over DynaGrow though? I don't know which is better.

If you've already got the trio, I'd just use that. It will work fine, but it's overpriced for what you get IMHO. Have you been using their feeding schedule? It's on the fox farms web site.
A lot of folks here use DynaGro Foliage pro, and I have personally used it with good results. It is cheaper than many other brands (including fox farms) and works very well. If you also use protekt, it's important not to cross-contaminate the two. I like to put them in ketchup & mustard bottles for ease of use & no cross contamination.
Protekt is a silica supplement and also provides little extra potassium. It is not required, but it helps plants by making them tougher. I've seen the results with my own eyes -- the stuff makes a difference. Way less likely to have problems with mold, mildew, or bugs.
I even used it on my wifes geraniums this year. They are HUGE and still going strong! Very unusual for mid-October. Same food as last year, but I added protekt. It also raises PH, which can also be helpful -- as long as you don't overdue it. A little goes a long way...

My Ph is 7 which seems a little high for a basic solution like Protekt. And no I haven't been using the feeding schedule accurately. Can I start now using from week 5?

Personally, I'd go with DynaGrow but I know a lot of growers who get good results with the FF trio. Either should work fine.
I use whatever I've got on hand and experiment a lot. Do you have an EC/PPM meter? They come in handy.
It's also a good idea to keep some type of log.
One of the biggest mistakes new growers make is loving their plants to death -- literally. Overwatering and overfeeding always bring badness. Don't do it!
Digital moisture probes are like $10 and well worth the money. On a scale of 1 - 10 they tell you how wet the soil is. Only water when it's less than 5 & you'll be golden.

Along with that^, should I flush?

PH of what? Your water?
Ocean forest is known for being slightly acidic. That's why people add a cup of lime. It doesn't need extra calcium. Already got oyster shell & bat guano.
You can start anywhere you want. If you're in week 5, that's probably a good place to start. (I've never used the trio.)

Why would you flush? You haven't been feeding them enough.

 

[Dr. Who]

Never ever been a fan of FF nutrients (other then big bloom)....
Very shitty charting.....Not for cannabis...

I use the fox farms ocean forrest and I get through 4 weeks of veg without needing to add nutes. I transplant into 5 gallon pot only filling it a little more than half full when moving into flower tent, then after about week 4 of flower, I top the pot off with some extra FFOF , Worm castings and perlite. OF course im using bloom nutes with it as well but ive had really good results doing it this way. I use the General Hydro Organics Bio Bud and bio bloom with some cal mag and mollases

Just got the Dynagro. Reading here to put only a fraction of a teaspoon per gallon of water. Using a 2 gallon pot. What do you think is ideal for watering? It has a lot of Nitrogen and one of mine is flowering so I was unsure if I needed that much nitrogen.

Go with a full teaspoon per gallon since they are hungry. EC should be around 1.4, which isn't a lot. On my meter it's around 600 PPM. Use a half teaspoon of ProTekt and make sure you add it to the water first. NEVER mix concentrates.
Different plants have different nitrogen requirements. It's debatable whether intentional fading with a low N bloom formula helps or harms the final product. Many growers firmly believe that high levels of P are counterproductive, but again, it depends on the strain. I believe it depends on the source and how soluble it is.
Sorry, don't want to get overly technical and confuse you since it's your first grow.
Allowing your fan leaves to stay green during flower has several advantages. Healthy green leaves are much more resistant to mold, mildew, and bugs. They also produce food via photosynthesis. When leaves turn yellow they become a liability to the plant.
I could go on, but you get the picture. My last grow was mostly organic and many plants were green right to the end. This isn't a terrible thing, but you've gotta make sure the cure is good or the final product could be a bit harsh.
I should also point out that some strains fade & defoliate on their own, regardless of how much N is available.

Thanks for all your help bro it's awesome. Check these pictures tho. I am kind of concerned with yellowing in the middle of the fan leaves towards top and bottom of plant. Sent pictures. Also some leaves at top are getting sharp edges
