Help identify leaf problem!~ Calmag deficiency? Phosphorous toxicity?

pillowzstarted grow question 5y ago

Need help to identify leaf problem (week7-9). Seems like calcium deficiency from the dots on leaf. May be indirectly from phosphorous toxicity and calmag lockout? Or is it from wrong soil ph? Not sure what I'm doing wrong. 😖 Please share some wisdom. Thanks! 🙌

water ph is 6.5 every watering. I tested the runoff ph was around 6.2 not sure if the soil ph is wrong from the nute deposit? I noticed this leaf problem started after I switched nutes to flowering. I used Flower Fuel 1-34-32 which might be too much too early?

What is your water pH? Do you add calmag to the water?

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Leave spotting Nute burn? Thrips? Some of those leaves where tucked aggressively at one point. I'm leaning towards nute burn. Think I over did it a little.

Leaves turning light green -- yellow (after 12h day/night rhythm)Since I started with 12h daylight/dark rhythm a lot of leaves started to turn yellow (older and lower ones first, some branches turned red). What I did: PH value=6.5. I added CalMag--no effect. I flushed the soil --no effect. Do you have any ideas? Thx green thumb-friends 👏

Spotty/Blotchy Discoloration on leaf.What is this spotty/blotchy discoloration on this leaf? None of the other plants have it, it didn't brush off when rubbed. Hoping it isn't a mold or a pest...I have been keeping the humidity around 65% with good airflow, but I'm wondering if it's time to bring it down to 60%.

Yellow lines on 2 leaves Any clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated

Flush?I have never tied to flush a plant and I seen if the leaves have too much yellow then it is not a good idea. I plan on doing a harvest in 10-14 days and wanted to know if both of my plants should be ok with a flush.

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?

There is a little bit of minor yellowing/browning in spots, on a few fan and sugar leafs. The plants otherwise seem healthy. Is this a normal part of this stage of flowering, or should I be concerned about nutrient issues? Thanks!
