If you're not ph your water you will run into lockout problems. It looks like lack of nitrogen but could be incorrect ph range issuse or over watering issue. 👍🌱

Cal-Mag and N Deficiency in Flower? Thanks!
I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Yellow leaves working out towards tips
Yellowing of lower leaves, from the stem working towards the tips. It’s been hot and they’ve been home alone for 5 days with just one water on the 3rd day. They had a small amount of bloom just before I left! During veg they were on fish mix, but not very much (1/2 dose).

deficiency symptoms
I'm a beginner and some plants are getting fallen leaves. They are being watered with the amount of approximately 10% of the volume of the pot and an average pH of 6.5. Runtz has Mag deficiency symptoms after I fertilized, is she also lacking N deficiency?

Yellow/Brown Crispy Lower Leaves
Why are my lower leaves turning yellow/brown and crisping up? Is this a nutrient deficiency, the top leaves appear to be good still, but it looks like it's slowly making its way up the plant.

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?
She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

I have uploaded a few more pictures - getting worries as the yellowing is continuing. Any ideas? pH was 5.6 on Saturday when I first mixed the nutes), and then with the air stone has come up to 6.5 or so. I've added a small amount of pH down to temper this back down.

Dry spots on sugar leaves, plant late in flowering, also spotted on another one in the same reservoir
Hi guys, my plant is around 2-3 week before harvest. What is the cause of the these dry spots on some of the smallest sugar leaves on my plant? The ppm might be too much and is around 1200-1300ppm. PH is 6.0-6.1 I've spotted it on one other plant in the same reservoir. Thank you

Please help! What am I doing wrong? I’m a first time grower
My leaves were burning and now I know that I am burning it with nutrients cause my soil already got nutrients. I’m only using water now but now they are turning yellow and the big leaves have spotting. What’s the problem now and how can I fix it?

Yellow spots nute difficiency? Light burn?
I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?
