Hey there so i agree with the look of mag deficiency, whenever the leaves have that margin discoloration (it always looks like a grid to me) i think mag. Its often with other deficiencies too and low ph. If your roots are incapable of absorbing it i would suggest doing a foliar application (close to lights out though) like you're doing...but maybe try epsom salt rather than an actual calmag sup, as E.S is mostly just magnesium.
I see you dont have a ph listed, if ypu don't have a pen maybe you can get your local water report to get the starting ph? I think mag does best 6.5-7. Finding a very finely ground dolomite lime to add to the soil may be the best option if ph is unknown as it helps to buffer the soils ph. I
hope you find your troubles and can fix them. ✌️ I know ph can be a nightmare, but it definitely helps rule out a lot of problems. Happy growing

I’m gonna say nute are to blame for this, 1. Light burn usually makes the leaves curve upwards think reverse claw and it would be even across the top portion of the canopy. 2. Nutes generally show minor burn on the tips working back. 3. PH for veg should be 6-6.5 easy flowering a bit higher. 4. Your HID light is a bit close your internodes distance is super compact so backing it off 4-5” won’t hurt either. Because the symptoms of this issue are all similar I would recommend checking the run off after a ph water only using EC to check for salts, I would also raise the light a couple inches and watch. Always check the newest growth to see if it’s corrected.

Hi, i was looking through your Diary, In week 3 it looked like a lockout, by wrong PH. But the actual problem looks like your lights are to near. Your plants are growing very dense and close nodes, and it looks like aLightburn to me. Rise your Lights and watch if the newer grow looks better. The burned leaves dont heal. even get brown or white in worst case. but if your light are more away from the grow it should not appear again

35% of RH so it can be a heat issue caused by the dryness , of not then it is a nutrient burn ( I would not bet on the nut burn ). If it was a mag def it would have been fixed by your feeding and as you'r working with soil I would just continue to give extra cal mag. Btw a big light with no more than 18h of light will NOT put your plant in overdrive so she will NOT be indeed with more Calcium , it happens to Autos growers who are using a light schedule like 20/4 or 24/0 and you can check that fact by using Google.

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

Deficiency or excessHello colleagues,please advise me, what could it be? the tips of the leaves are sometimes lighter, and the holey leaves? I didn't find any pests in the tent. I use the AH set. Once a week I only rinse with water with enzymes. Can you think of anything?

Dealing with Nutrient Burn and Salt Build-UpI've observed salt build-up and nutrient burn in my plants recently. I've taken action by flushing and removing 60% of the affected leaves. Now, I'm considering whether to remove the remaining affected leaves and when to proceed with top dressing. Please advise.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

Yellow / brown leaves tips; should I worry ?Hey ! My 3 plants (same strain) are showing yellow / brown leaves tips for a few days, and I'm not sure what it could be. I'm thinking mild potassium deficiency, or perhaps a bit too much nutes ?FYI, I'm strictly following Biobizz chart, every watering. Should I worry ? Thanks !
