started grow question 1y ago
My Lemon Cherry Cookies has had brown spots on the leaves for a while now. I'm fertilizing according to the BioBizz schedule with half Grow since it's already flowering. I also add 1ml/L of CalMag with every watering, check the diary.

Leaves problems
Can you please help me ? This little one is week 9, but seem to have a lot of trouble :( Also, I can't find the perfect watering spot. It's indoor with 18L pot, but if I'm watering more that 1L each 3 days, it's wet all the time. How can I do ? Thanks a lot

Is this TMV? It has 6.5 ph in and temps remained within normal parameters. Had thrips infest. Mostly gone no real new activity but I think I got Tobacco Mosiac Virus. Never seen it myself before just wondering if I am correct.

Hey everyone, I've had these brown spots on the old leaves of my little plants for a few days now. In the weeks before, I fertilized, but only with 1 ml of BioGrow, 1 ml of BioBloom & 2 ml of CalMag from BioBizz — I think it's more of a deficiency. Thanks a lot for your tips!

Potential bud rot?
My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early? I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

My Blue Cheese Auto isn't doing so great... In my opinion, it shows signs of clawing and root rot, I need tips. It's in a 19L pot, I know it's a bit big. I have clay pebbles at the bottom and then mixed coco with all mix and let it grow in coco on top.

Leaves are gray/brown and curl down. HELP!
Im a first time grower and I cannot figure what’s wrong. I’ve been feeding it Calmag and Grow from Biobizz since last week. 1 ml/l grow, 0,8ml/l calmag. PH of water + nutes is 6.3. The soil is coco and pearlite. Did I give it too many nutrients? Did I overwatater?

Brown dark spots on fan leaf
Any clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.

Brown spots
I'm having what I think is a cal deficiency. Ive been using calmag for a week or so now. Just curious if this will ruin my end results? It looks pretty bad. Buds still look nice though. Any thoughts?
