Hey, these are signs of calmag deficiency, these brown spots are the main symptom. Add some calmag and you’ll be okay 😊

500 or 700 ppm ?
500 is a bit low, 700-750 ppm (NaCl 0.5 scale) should be fine

leafs with brown spots and olders become yellow and curledI'm trying to figure out what is the problem with the growing of my plant.
The upper leafs are quite normal, even if they tend to bend downwards.
The old leafs start with brown spots and then they become yellow and curled on the peaks.
Please help me to understand what's going on

Dark green leaves in meringueIs my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?6y ago

Brown spotting?Hey everyone!
My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean?
I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

K deficiency? Or something else?Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

Deficiency/Light Stress IssuesWhat else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

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.

Possible manganese deficiency?I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.
