What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Spots on leaves, dying leaves, afraid of bud rot later. Last grow same plant-similar problems in the end bud rot. SleepyJoe Strain.
I was advised 10 days ago that my plant was overfed. Since then it has only been getting 6.5 water and unfortunately new problems are starting to appear. 100% organic soil biobizz fertilizer, using the manufacturer's recommended "all-mix". Their environment is consistently perfec

When growing different strains in a RDWC system how do you balance plants with different nutrient needs. My amnesia auto ran into a major cal-mag issue and now is experiencing nitrogen toxicity, while my feminized Jack Herer's are largely unaffected. Thanks for the advice.

Is this Calcium Defic? What to do to fix?
Week 9 flower. Rust spots on leaves. Starts at top. This can only be calcium defic from ALL the research I've been doing. Can anyone chime in? I foiler spray a CalMag before lights out and I've added some more to the nute mix. 6.2 pH, runoff seems good.

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Brown Edges on Leaf. Bit of yellow and purple.
What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

could this be due to the PH being too low?
I watered 3 days ago with PH 6.3 Ruoff was 6.0 today watered with PH 6.6 runoff was 6.1 Can the brown spots come from the wrong PH ? fertilizer is full BIO BIZZ CHEEMA, worm humus and mycoriza what would you recommend to do ?

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Is this pH related?
Hello, mates! Anyone knows what this could be? Searching I found that it could be pH related. I use pH controller from ferts (pH perfect from advanced nutrients) since the beginning, so I think it's odd that it could be a pH issue. p.s. 3.5 weeks of flowering Thanks 🙏 🙏

Brown Spots on Leaves
I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Burn, deficiency or other?
I’m completely stumped as to why my one plant is showing signs of deficiency or burn. Used the exact amount of fertilizer per plant. One plant is fine and the other looks terrible. I used a half dose of cal mag and it seems to have stopped but is not drinking or looking better.

Rusty spots mid-top of plants. A couple on each plant. Thoughts?
(Check diary for more details) Thinking calcium deficiency, also maybe magnesium deficiency on a few low yellowed leaves. Thinking it could be nutrient lockout? Feeding them 6.25 pH always. Gonna try 7.0 once and 6.5 for awhile. Thoughts anyone? Im still fairly new and learning
