VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.
Lol_You_Lookedstarted grow question 2 years ago
Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months

The only thing vpd will really effect is rate of growth and over all yield come flower. This is more of a ph issue with your reservoir always keep an extra ph pen handy or even some strips as a sanity check.

It should be stated, this is done in Hydro with 20ml of CalMag for 3.5 gals of water.

10000000 % ph related calcium issue.
Meters lie, even most exoensive or brake sometimes.
Could be aftermath of light overwatering , that swings pots ph, aka watered while pot was still a bit moist.

I see that it is in bloom and consequently it eats more, the spots may be due to a lack of potassium or magnesium, but very often it is a problem limited to a few leaves, practically nothing is perfect ... keep it under control in the days to come , if it gets worse it needs more food, if it stays the same then it's a limited problem.

Curled leaves and brown spotsPlease help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.
Started around 6th week

Yellow tips at bud-leafsWhat is the worst case of what could happen to the buds and the harvest due to the yellow tip burn?
Since 5 days the near leaf buds have yellow tips.
It could have any reason. Flys, high ph, to high nutients.

Is this nutrient burn?As a beginner it is hard to classify that: Are the brown tips a sign for nutrient burn? Or rather a deficiency of something?

First Grow Help And FeedbackHello Grower,
OG Kush Flower Day 24: Lollipopped and defoliated 10 days ago. Can/should I defoliate again? The buds seem like they could get more light. Also, I noticed some sprinkles on the top leaves—could this be from too much P/K? Any tips and general feedback are welcome!

But since I’m in flower week 6, I have curling leaves, normal?

Nute burn? How to handle?Hi, i guess i made the typical newbie mistake and over-feed a little bit. The plant started to get some brown/yellow tips, mostly the upper part of the plant.
Is it enough to just stop with nutrients and stay with clear water or is there anything else i can/should do?

Potassium and Calcium deficiency?Both plants are autos on day 49 after sprouting.
Plants didn't get any fertilizer during veg. I noticed deficiencies about 2 weeks ago, and added BioBizz Bio-Bloom, Top-Max and CalMag to next waterings.
Planning to alternate water and feeding for the rest of the grow.
any advice
