Not sure what's hurting my plant

A question from a fellow grower:

I recently start using fertilizers on my plants. I bought logic grow a+b and cag- mag pro from greenleaf nutrients. I used them once as directed but Im not sure what’s hurting my plant. These is how it looks the one leaf turned yellow and the other one twisted.

pH? Of the soil and of the fertilizer mixed in water, please :mask:

do you do ppm? That too, if available.

It needs support and a fan, but don’t have a strong breeze on it. So light, you can hardly see the leaves move.
What are you using for soil? Pile a little around the base, and do not over water.

fan is always better than support you want to teach plant to bare it’s own weight

Answer these simple questions the best you can.
If you do not know, or do not use something; Just say so = NA

Strain; Type, Bag seed, or NA

Soil in pots, Hydroponic, or Coco?

System type?

PH of runoff or solution in reservoir?

What is strength of nutrient mix? EC, or TDS

Indoor or Outdoor

Light system, size?

Temps; Day, Night

Humidity; Day, Night

Ventilation system; Yes, No, Size

AC, Humidifier, De-humidifier,

Co2; Yes, No

I’m not sure what Ppm is.

Saliva dominant, super skunk, autoflower
Soil pots, closet
Ph is between 8-7
I believe the strength of the fert is EC. What is that ?
Les lights, 45 watts 3 plants
Temperature 70-75
Humidity N/A
Ventilation system: I have a really small fan and a air purifier inside the closet. On then lights are on.
No Ac no co2

The other plants look really healthy I believe, and I think the soil is drying out quickly.

How many times per week should I use the ferts? How much quantity to each plant?

What type of soil, a store bought brand or a home made mix? Name of the brand, please.

Do you have a pH tester?..exact numbers are needed…you should aim for 6.5 pH

Ppm is parts per million…it’s a reference to another tester, a ppm/tds/ec meter.
It measures mineral (salts) in the soil, in reference to fertilizing, which a new plant needs little of.

I bought jiffy natural and organic soil mix seed starter. I do have a ph tester but it’s not a digital one. What should I do reduce ph levels naturally or home based??

Parts per million is a measure of dissolved solids in water or nutrient solution EC is same thing just using current electrical conductivity to get same info
Kabongster is right your ph is very high and your plant is failing to get a nutrient it needs

How should I reduce my ph? Or how should I addreess these issue?

If you have a meter you can reduce ph by adjusting the water and nutrients you put into plant so it is closer to target ph 6.5 for this you need to test before watering and use PH dwn to lower ph of water if you have hydro store in town they will stock ph up and dwn if not pet store in the fish section, or even auto store battery refill kit works well. If your ph is in correct range the plant will utilize nutrients avail if not it won’t don’t add more nutrients until ph is corrected or it leads to build up in soil which is worse

Your soil is pH 8-7, get an exact number, but you would mix water in the 6.0 pH area to lower the soil to 6.5 or so…

Thanks for your help man! I just purchased ph adjuster up and down. However it will take until thursday to get here. Should I use vinegar to lower my ph levels in soil? Should I use directly into the soil or mix with water and then water my plants with the mix? I’m not sure how to use the fertilizers I bought. I have a logic grow (similar to sensi grow) and cal mag plus. Their are in powder form. How should I use them? should I have 2 diferente reservoirs? One for clean water and one for the mix of water and ferts? Obviously is my first time growing, everything has been fine for the last 4 weeks that I started planting but now I just experienced a ph problem.

you can use lemon juice to lower ph.


Start slow, feed lightly…you can always feed more, but over fertilizing is harder to fix.
The plants have many feedings ahead, months worth.
