My little girls are looking wierd and I’m wondering what y’all’s thoughts are?

See pictures I have from 3 seedlings. Leafs have discoloration, looking light. My research supports either nitrogen or iron deficiency.

My user error could be foliar spraying too much or too much differential in low to high humidity, with 40% - 70% (Low - High) daily.

These are about 3 weeks, since planting germinated seedlings.

- 3 gallon smart fabric pots
- FOXFarm Ocean Forrest-lime-perlite
- NO nutrient feeds yet, only PH 6.0-6.5 water

I’m thinking I need to provide some nitrogen within their next watering (Grow Big FF) that should help this issue? But if it’s iron deficiency, then how do you fix that?

Let me know what you think, any advice or thoughts are welcome.

If there is no issue, and my plants are just young and discolored because of my foliar spraying for the increased humidity, that would be awesome too.

I use distilled water because I don’t have RO system and I want to start from scratch and not feed the plants any unnecessary. I know what you mean about the nutrients dropping the PH like crazy. I usually add 1/4 portions of cal mag & Fox Farms Big Bloom to help buffer the distilled water so I can adjust the PH. I’ve found this Fox farms ocean forest is a little light on the Calcium and Magnesium side, and usually have that deficiency pop up if I don’t add in some cal-mag.

I used spring water cheap gallons from walmart were at 120.

Ill try the silixa thing again and see if it works. I dont think it did though

Flowable lime might help. never used it

Sounds reasonable but depending on the spring and the company some are easily 400+ppm

Is there any cal. Mag product/s that solublize in water to give us natural alkalinity?

The 6th photo from the bottom is im almost certain a ph issue.you are in ffof. Your ph should be 6.5.
Need to find out what your soil ph is.

You got a spare 100 bucks lying around?...Extech ph100 soil ph meter is the ticket here. I have one and it works pretty darn good

MegaMan2003 said:

yeah I PH the water to 6.3 or so. But I’m thinking I’m still to high on the PH. Going to go for a 6.0, and I was thinking PH issue could be it. I know they should have plenty of nutes available in the soil still. Just not able to take in the nutes because of PH being too high.

I have the same problem with one of my plants. Leavs are crumpled with such pale spots on them. New leaves seem to born with those defects already. In general the plant seems to grow a bit slowly. Can't figure out, what's that.

I grow in coco.
Fertigate from seedling stage
Use a lot of CalMag - so cant be sure, the problem is with it.
I use water with 75 ppm, solution PPM 600, PH is about 6.0. I check PH with 2 different calibrated meters, they show the same numbers.
I also have another plant in the same tent - feed it completely the same and it doesn't show such symptoms...

Do you use LED ?
Did you have problem with germinating a seed? I had one - put my seed between too wet paper towels. Now I think, maybe this was a case.
Did your plant stretch to the light at the beginning?
Did it have problem getting rid of helmet?
