[ReptillianSorcerer93]

Problem: rusty kind of looking spots.

Medium/grow method: biobizz lightmix

Feed: and supplements used: biobizz GROW, BLOOM, TOPMAX, CANNA PK13/14

water source: TAP WATER LEFT FOR 24HRS

Strain/age: blue dream auto (50/60days) & sweet and sour (30/40days)

light used: 2x invisiblesunled 250w dimmed 120w each.

Climate: lights on 26c 50% lights off 22c 55%

Additional info: Blue dream is on 2ml grow/2ml bloom/ 0.5ml topmax/ 0.5ml PK13/14.

Both plants started looking like this a few days ago. I dont PH my water. I thought using biobizz it'll be fine.

Any help would be much appreciated!!

Cheers man, i was worried upping the nitrogen because the tips looked a lik burnt. I'll up it abit tomorrow on the next feed. Best to check the run off or just ph the feed tomorrow before watering them?

I always check ph religiously. I check it when nutes are mixed and run off. I’ll be posting in live chat in a few minutes and you can check out my grows. My leaves are yellowing on Sour Crack as she will be harvested in 2 weeks. My leaves look like urs

Rept'- looks like some P defc., some N too,... maybe Ca as well... What feed dosage and freq. are you doing? She looks kinda long term underfed, and hence the fan tapping for what mobile nutes are in them,...some is normal, but this is too much too fast.

:smoking: sorry mate, I got busy with harvest and such!

Hmmm, that seems OK for dosage per L,.... buds are fat, so demand is clearly high... up the dosage a bit across the board for a week or so, see if that slow it down,.... Biobizz is mild stuff after all, and I see defc.'s commonly with their line... Different strains/pheno's have different demands too so there's always that x-factor in the mix!
