Is this a nutrient deficiency?

[Tofta]

Hey guys, was wondering if this is a sign of nutrient deficiency?

If you can and have a minute, you can fill this out......

1. Are you growing from seed or clones?
2. How old are your plants?
3. How tall are your plants?
4. What type of hydro system are you using?
5. What brand/type of nutrients are you using?
6. What is the Ph of your nutrient solution?
7. What is the PPM/EC of your tap water?
8. What is the PPM/EC of your nutrient solution?
9. What is the temperature of your nutrient solution?
10. Does your PPM/EC show a rise or fall when you do your daily PPM check?
11. Does your pH show a rise or fall when you do your daily check?
12. Do you foliar feed or spray your plants with anything?
13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
14. How close are your lights to the plants?
15. What size is your grow space in square feet?
16. What is the temperature and humidity in your grow space?
17. Have you noticed any insect activity in your grow space?
18. How much experience do you have growing?

Growing from seeds, organic soil, coast of maine shouldn't need to add nutrients but the bags did freeze so some nutrients loss should be expected. Grow size is 4x8x6 have 800 watts going between 4 200w 2000r's that have Samsung 301h's. I have them about 28" above at 50% and have a ppfd/par around 200/270 depending on location, can add another 200w but with 4 of them I have plenty of light especially at half power soil ph varies from container @ 7/7.5. Don't do PPM test so idk about that. They get watered every other day with no nutrients Temps range from 77 to 83 and humidity 75-83% with an occasional swing into the 40's if the humidifier turns off. Only 2 bugs have been found, one spider and one little flying nat but have not seen any activity in days. This is my first grow.

Going to try calcium and magnesium additive since I use RO water. Only thing I can think of outside of the soil being left outside over the winter.

 

[Bilber]

You say that you water every other day........

How much......like until runoff or just a cup......

I don't run soil, but the list you filled out will help others help you.....now they will know the basics of your grow....very helpful info....

I am wondering if you're just barely giving them just enough water to stay alive.....

Others will be around, but it's the watering habits that get most new growers a hard time....

 

[Bilber]

I would like to think that isn't the case.....reason being is that big chain stores, home depot, lowes, tractor supply....

They leave their soil out all winter.... I'd have to say no, but soil didn't agree with me......

Move your light farther away.

 

[Tofta]

Move your light farther away.

You really think it's a light issue? It's already above the recommended height and on a lower power setting....

 

[Tofta]

I'm going to try and get my ph level down, my thought is if the soil is at 7.5 it will have a hard time getting any nutrients from the soil

He’s 100% correct.

 

[Tofta]

He’s 100% correct.

So should the ppfd be around 100/150? I thought it was supposed to be in the 200/300 range?

 

[Tofta]

So a little over an hour after adding some nutrient rich soil over the seed starting mix and feeding some 6.0 RO water and she already looks a petter hue

Manufacturing specs you should throw away.
These are basic outlines. There is no one size fits all cultivars method. Every strain is different. Some like up to high out put, others don’t. I veg with my lights at least 30inches above canopy in veg. Sometimes less is more.
That light needs to be raised. In both my flower and veg rooms. Look at the space from canopy to light. Big ass space right?????
No strain is created equal homie!
Always use cal mag with r/o water. Good luck.

Alright got them up to a little over 30. I appreciate the info!

Nice. Now if they start to reach or the spacing between nodes gets to be a little lanky, that is when you start to drop it down little bit at a time. Also just because you raised the light by no means does that mean to turn up the lights output. Just watch them and see how they act over the next week. Keep us updated homie!

I'd add some Epsom salt to help the plant photosynthesize the light better.

 

[Tofta]

Some good growth in the past day, really starting to thicken out!

Cannabis likes a ph around 6.5. my first though was not enough N.

Soil run off was 6.8 after adding some bonemeal and watering

 

[Tofta]

24 hours after adding calmag water ph was 6.33
