that chart is for soil, many people grow in water, which needs to be 5.8ish, coco coir, which likes it to be around 6.1, or peat mix, which likes about 6.3....

it is a good idea to let your ph swing up from 5.8 to maybe 6.3, then correct it back down to 5.8, for exactly the reason you're saying, to prevent lockout of minerals that need different ph ranges.

Absolutely love to see my thread goin up after my first indoor grow by 2011.
At that point i was breeding good genetics (purest afghani persiam kush ) even you can smell hell by the start vegging never seem bigger leafs likes
So this is my nutrients test clothet alwyas contributing to find easiest and more effective nuts then go big

This is why if you researching find out less growers used any booster on flowering stage except light foliar (just for 2 weeks) .
You couldn’t do bloom booster more than 2-3 times and it cause absulutly light burn .
I have to day for water the best is set up by 5.5/5.6 then up to 6.2 then correct it .
Really appreciate your post

All those charts are bs because they leave out temperature which is proportional in some ways to pH due to ionization, which increases during aeration.. You do bubble rite.?
Ive had some systems down to 5.3 with no lockout and were super healthy plants. And others with deficiency at wht most consider optimum 5.5-6.3...
Considering my meter is inexpensive lol
Maybe i shuld switch to a 10-4-4 wuld you roger that ?

What up
Just wanted some advice as to what could be causing the yellowing on the fan leaves? Its mainly from two of seven plants. First week of flower amd ive been using cyco bloom at half strength with gh calmag, plus some molasses and silica. Ppms are about 7-800 going in ph within 5.5-5.8 as directed by cyco. However ppms in runoff are about 500.
All plants are in coco however two at the back were transplanted from canna terra. I get the yellow leaves with the burnt tips are nute burns but wondering whats causing the yellowing from the middle? The veins suggest some type of chlorosis and my first guess is iron? Let me know your thoughts as this is my first grow. Rh is in 60s atm and temps range from 23-28 celsius.

i use my marshydro 600 led keep 18/6 sometimes 20/4, never do 24/7, but hope to know any difference there?

Marshydro 600 nice choice
I have good results vegging that way 20/4 sounds more realistic lol
If the yellowing started at the base and moved to the tips it could be sulphur def.
Best of luck, nice herb !!

Its hard to say for sure it without the ratio of NPK used it may and usually is combinations of things mixed with pH fluctuations, magnesium defs usually cause yellow margins between veins as does potassium, but growth would not be as thick if it were not available, if they are setting up for flowering it could have used up either of the above nutes quicker than usual and cause a def.

Yeah the stretching would have caused it, ill up the cal mag, its definitely getting enough k as ive been feeding everyday. Just flushed with bloom nutes and calmag yesterday and i think its getting better. Thanks.Marshydro 600 nice choice

, but i heard that use sulphur will damage the light. you use the sulphur during the plants growing ?
have you used other lights from marshydro? like the cob, i see the forum see many guys do diy cob light, do you think it's safe to diy a light ?

I've never been able to find a copy of the plant abuse chart that was of a decent resolution- this thread is awesome. Thanks to everyone posting info in it. I recently discovered that one of my plants was starved for N during flowering. It had all the symptoms of low N but being in flowering, I suspected lockout. The solution turned out to be a couple shots of veg stage ferts. I'm not sure why this plant is such a nitrogen slut, but if I skip the vegging nutes for a single watering, the plant shows it.
The point of the story above is that I learned to trust what the plant is telling you, not what makes sense. Learning to watch closely so you can determine if something starts at new or old growth, or at the tips vs veins, etc. is key. Note any changes, including the progression, and then as OP said way back at the front, make reasonable changes. Know this info, do not freak out and overdo whatever corrective action is needed, and trust the plant.

I lack of grow experience and also the knowledge, i recently check on this page https://www.growweedeasy.com/
Also i found marshydro site their grow tips for led grow light， dont know if there is any better explanation about led grow light tips for growing.
https://www.mars-hydro.com/led-grow-light/mars-ii-led-grow-light/buy-mars-ii-400-led-growing-light-good-for-medical-plants-in-door-hydroponic-seeding-growth-flowering-for-sale
1.How do I determine the right light for my grow area?
Measure the floor space. Multiply the length times the width and this will give you the square footage. You should be able to get decent results with 30-50 actual watts of power per square foot.
2.For larger areas should I go with a single large panel or multiple medium to small lights?
Using multiple lights allows you to better distribute the intense light in more areas of the grow space instead of having all of the higher intensity light concentrated in only one area while the outer edges never receive intense light.
3.Recommended Hanging Distance Above Plants
Seedling stage: 20''~28‘’ Veg Stage: 16''~20‘’ ;Flowering Stage: 10''~16‘’
4.Here are more tips for grow under our light:
Growth stage, turn Growth switch on. Bloom stage, turn Growth and Bloom switches on.
5.Recommended Lighting Time
Veg: 18/6(on/off) or 20/4(on/off) Flower: 12/12(on/off)
6.Recommended Growing Conditions
The rate of photosynthesis and transpiration are directly affected by temperature, humidity and airflow.
The perfect temperature and humidity for your plants are found between 75°-85°F and 50% - 70% humidity, with plenty of airflow to replenish CO2. PH is 6-6.5. You may add more calcium and magnesium than normally needed.
7.Please Note
The light is not water-proof, so do not use it under water environment.
Light may be too strong, please wear your sunglasses when looking at it.
Some leds seem dim. They are IR. Human eye can not see IR very clearly, but you can wear sunglasses to check.

Open to any opinions. Young (just about 3 weeks since germination). Probably over nuted a little (using Jack's at 1/4 strength), probably overwatered. Still in Solo Cups. In soil (Ocean Forest), tap water (aged a few days_.) Am I overthinking shit?View attachment 4161343

Hey buddy,What the lamp you use ? led or hps ? if it's led grow light, you need less water and nutrients. check the link i found tips for you.
