That's not light burn that's calcium defeciency. If you're using high powered led lights, this would make sense as the plants tend to use more calcium and magnesium under these type of lights 🌱👍

Looks like a cal deficiency. I had this problem too caused by too much P or wrong pH.

CalMag deficiency/ Nitrogen toxicity/ Wind burn?Thank you 8thChevron for your help!
Run off readings:

The fan was directly on them so have put that down to the floor now.
Have also just flushed through with a half nute mix that was 6.3ph, 134ec & 549ppm

Leaf burnt edgesOne leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

Leaves yellowingThese leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

Organic dry amendment replacement for bottled cal-mag nutes? (Preferably off-the-shelf)I always seems to run into calcium issues (rusting and interveinal chlorosis) around wk 4. While early use of bottled cal-mag (TPS, "organic") has worked very well, I'd like to be able to simply add an additional organic dry amendment in my line-up vice bottled nutes. Any ideas?Week 2

More rusty spotsSee this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing.
Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.5y ago
