How does 1 properly PH?

[Garden Knowm]

Hi Weed..

you should do fine with those temperatures as long as you have GOOD airflow.. lots of fans blowing around the room..

Will your lights be on at NIGHT time.. or DAY time?

It is always safe to water with 6.8 PH water... If you know your soil is higher than 7.0 then you may want to water with 6.0-6.5

Or if you know that your soil is 6.0 or lower you may want to water with 7.0 water... You definitley don't want to make any careless decissions and over compensate.... LOL

hey garden knowm which miracle gro soil do u use? what is the exact name. also if i use miracle gro soil will it be okay to still use nutes?

Hey Garden Knowm, I have my lights come on at 5 pm and they turn off at 11am. I think my soil is around 7, but I havent tested it yest because I just got outta knee surgery. They did a acl reconstruction and fixed my miniscus cartilage. I will have my nuted water at a ph of 6.-6.5. Last time I checked my water with sum superthrive it was at 7.0-7.2. I was a light greenish color.

I have a fan accross reflector to remove any heat, I have a smaller fan blowing on the plants, and a third one in the bathroom ocillating fresh air in and hot air out, plus I have air conditioner running during the daytime to bring temp down to 80-82 degrees when air is on. It seems like I have to water plants more often since I have switched to 400w hps. I give the plants about 12-16 oz each daily except my youngest plant. I will be putting them to flower in 3-5 days and I will need to tie down 2-3 of my plants if they turn out to be females. They all look really good compared to my last 2 I had. Thanks Garden Knowm!! U rOCK

another question for you Garden Knowm, I looked up a problem I am having with Potassium Deff. and The guide I was reading identified my problems with the tips of the leaves yellowing and curlingdown a little and sum leaves are twisted from mag deff. here it is read: 3) a) Margins of the leaves are turned up, and the tips may be twisted. Leaves are yellowing (and may turn brown), but the veins remain somewhat green. >> Magnesium (Mg) deficiency.
b) If not, go to #4.

4) a) Leaves are browning or yellowing. Yellow, brown, or necrotic (dead) patches, especially around the edges of the leaf, which may be curled. Plant may be too tall. >> Potassium (K) deficiency.
b) If not, keep reading?
So my question is I understand to correct the magnesium problem w/ epson salt(1tsp per gal), but What gives me potassium? HElp please. I have had this problem before now I know what it is and need to fix both symptoms.

Weed4Life- PLEASE HELP

Flush your plants and give them a balanced fertilizer.
1 tablespoon per gallon of epsom salts is quite a bit. I would start with 1/4-1/2 teaspoon instead.
If you are already using a balanced fertilizer and still seeing deficiencies in your major nutrients, a pH imbalance may be making them unavailable.

Hey stinkyattic, I am seeing a deffiency. Now about flushing, I tried to flush my last plants and it seemed like it wasnt draining the water out. I believe I put a bunch more holes in all the pots after last plants(used a knife).Now would you say to use a gallon of distilled water per plant? I will take more detailed pictures of plants and of pots, and nutes with pic of color of ph level of nuted water as well. Plants just went into dark ages and will be back online at 5pm.:rasta:
Also, you are saying to add maybe just 1/4-1/2 tsp of epson salt to nuted water right after I balance out my nutes? Now, do you give nutes every watering or what? Does anyone know of a feeding schedule for plants? I normally give ph'd nuted water for about a week. then switch to half distilled/half cured tap water(1gal) for a week depending on how the plants look.
Stinkyattic, were trying to say that it might be in nute block or something? I read about that yesterday and to fix that 1 would flush his soil, feed his plants with ph balanced nutes? I normally add half of the stength of recommended dose that the nutes tell me and just starting adding a little superthrive once a week . Thanks!!!!!!!:dance:

Sorry weed.. for the neglect.. I have been BUSY!! LOL

can you post a picture?

If it isn't draining your soil might be too heavy/rich; perlite is a good fix for this.
That's another indication you might have a nute block rather than a straight deficiency- waterlogged, acidic soils are BAD!
Rather than a knife, I'd go for a paddle bit on a power drill to get nice open holes. The buckets I flower in got holes drilled right up the side so more O2 gets to the roots. They drain very well now too.

Now would you say to use a gallon of distilled water per plant?

I believe the rule of thumb is to use 3x the volume of your pot. So if you have a gallon pot, use 3 gallons of water.
Some sources say to use a very weak, balanced, pH'd nutrient solution to flush with, at no more than 1/4 the strength you would normally use.

Also, you are saying to add maybe just 1/4-1/2 tsp of epson salt to nuted water right after I balance out my nutes?

Yeah. That's the rate at which I apply the stuff, once every 2 weeks or so.
I would urge caution so you don't end up with an overdose. The literature on this subject notes that MAgnesium deficiency appears much more severe in very wet and/or acidic soils. So it may turn out once you get your soil pH worked out that you never really had a deficiency to begin with; it was just blocked.

Now, do you give nutes every watering or what?

Personally I do. They get their regular fertilizer at the recommended strength at every watering. They also get supplements. They get a carbohyrate supplement, Silica Blast, and Super Thrive every watering (flowering plants skip the S.T.). Then, depending on how they look, I give them a little fish goo, or kelp goo, or bone meal, etc. every few waterings.
My schedule is pretty flexible, since I'm still growing several strains from seed I haven't tweaked it for one specific variety yet. Once I choose a few good mommies it will be a different story!

Stinkyattic, were trying to say that it might be in nute block or something? I read about that yesterday and to fix that 1 would flush his soil, feed his plants with ph balanced nutes?

Exactly. Someone correct me if I'm wrong here, but it seems that for most micronutrient problems, it is the pH, rather than the absence of that nutrient, which is the culprit.

I normally add half of the stength of recommended dose that the nutes tell me and just starting adding a little superthrive once a week .

I didn't catch what you're using for fertilizer. Superthrive is good, just a drop per gallon, in veg.

If you're using a fert meant for MJ, you should be just fine using it at the dose it says on the bottle for 'regular watering'.

So get your drainage sorted out as a first step, and it will be easier to pin down what is plaguing your babies!

[Weed4Life]

The soil I am using is Expert Perfect Mix with an NPK of .10/.08/.06.
My veg fert. is either MG house plant food with an NPK=8/7/6 or Expert tomato fert NPK=24/8/16, and for flowering I use Shultz bloom plus NPK=10/54/10 and then I have superthrive. So U say not to use S.T. for flowering right?Ok. I do need to drill holes in the side of my pots for proper drainage. Now in order to drill the holes in the pots I have to tip pots upside down(being gentle) and let the dirt/plants fall out w/out damaging rootball and drill holes in the pots? I need to figure this out today because my plants are thirsty/hungary(soil is just about dry).

So by properly flushing plants, does that put my soil at a certain PH level? Here is pics of everything I have. I know I have to drill holes in pots. On my next grow, if I use perlite as part of my soil, do I mix it in with the soil, or do I have the perlite on the bottom? And is perlite going to cause any mold or any problems I should be aware of?

[Weed4Life]

Here is a few more pics. PLease tell me what I need to do and if you think flushing will help me out. Also,the first pics are of my oldest plant which I dont care much for, but the other pics are the ones I am concerned about. Thanks everyone for your help!

Can you see the leaves tips curling down? Also the leaf tips are yellowing and then turning brown and then affecting the edges all around.
