Leaf diagnoses help on my Strawberry Lemonade

[CassieA]

Hi there, I’m looking for some help please. My leaves are telling me something but I’m not sure what. I’ve noticed some white spots appearing on a few leaves. I’ve also notice some burning on the tips. I’m surprised to see them the tips burn because i thought my feeding was pretty good and I assume it’s Nute burn. If anyone has any suggestions on what I can alter please let me know.

Strain: Strawberry Lemonade grown from seed

Grown in coco

Feed 1/4 strength (2.5 ml per gallon) of GH biothrive grow Every other day with 4.5 ml cal mag added.
On the non feed day i water with 4.5 ml per gallon cal mag added.

Light is 300 watt mars hydro led. On 18/6 schedule.

Ph is usually a steady 5.80 but the odd water or feed will be 5.83.

I do not test EC (i have only read about it)

When I test run off water (I get lots of run off) PPM is about 450-475 ish.

Looking to stop any issues before they become problems. Other than some spots and white / burning tips I think the plant looks great.

Hiya cassie, over all they're in good condition. I was always under the impression you should feed everyday with coco.
Also your ph is good, but hydro sometimes likes a ph range between 5.8 to 6.1, so maybe try a little closer to 6.0.
They're in such good condition that it's just fine tuning you need to do.

Thanks so much for the reply. Very reassuring to hear that You think things are fine. I started feeding every other day because I assumed that the tips that are a little white and a few are a little burnt. I assumed I should cut back on the feeding even though I’m feeding quarter strength. Maybe the leaf tips are from another deficiency or excess? The below picture is from the plant growing beside the strawberry lemonade. This one is pineapple kush. Feeding is the same as strawberry.

I like the idea of bringing the ph closer to 6. I find I’m using so much PH down to bring me to 5.8 (over 5 ml/ gallon) of rootfarm phdown.

5.8 is good. The range for picking up nutrients includes 5.8 to 6.1, so it's good to vary between those levels.

Oh, and just to let you know, ppm and ec are the same thing just using different scales.

That is great info to know. It saves me from looking for and buying an EC meter

Hi, over the past few days I’ve made the adjustments that were mentioned but hoping for some more advice.

I’ve since transplanted into bigger pot too

I’m still noticing that the new growth has lots of white tips. I still can’t see how it’s nute burn seeing that the organic GH biothrive grow is being fed at 1/4 strength. Might it be another deficiency or excess nutrient?

Could this be light stress? I noticed that my timer had been bumped and the lights were only off for about 2-2/12 hours per day instead of the 4.5 inusually give them.

It’s the white tips on the new growth that I’m worried about.

Thanks in advance
