Deficiency Or Burn
GMSgrowsanswered grow question 6y ago
Your ph should be at 5.8 for veg 6 to 6.5 for flower. Your solution temp would be best at 62 to 68 to keep roots healthy and vigorous growth. Cheers friend

I am seeing an issue with the lower fan leaves and it seems to be progressing upwards. The leaves are yellowing and also seem to be turning brownish. I added CalMag into my last feeding but beyond that not sure what I should consider, info/advice is appreciated. See last pic wk5.Week 5

Chocolope Tent (Nutrient Lockout?)My choclope photoperiod plant gets brown spots while her sister receives too little nutrition. I think it's a nutrient lockout. (2/3 weeks left from harvest)
Ladies get Plagron COCO A+B and Green Senations. I don't see any mold, air circulation is good.

Fertilizer burn or something else?Hey fam. Plant seemed fine a few days ago besides a mag deficiency.
Decided to foliar spray cal mag at half strength a few times.
Now there are brown patches and leaves/stems are curling down like they’ve been overwatered.

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.

Leaves looking f’d?What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Yellow bottom leaves/brown spots on bottom leavesHi guys,
So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her?
Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else?
Besides this, the general condition of the plant is good.
Tx!

Should I start fertilizing or monitor the pH?Hi, I'm a beginner, about 10 days after switch, my lower and slightly higher leaves started showing signs of damage. I grow them in a greenhouse in strong sunlight, but I think that they don't get burned, I haven't fertilized them even once. What do you think of this?

What is this deficiency?They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.
