The problem there is almost definitely the ph. You need to raise it higher, why can’t you raise it? That looks like a calcium deficiency and maybe some ph spotting too due to the low ph. You really need to get that ph up to 6.2-6.7 ish

You need to add some lime to your soil. You should stay with veg nutes until flowers form. Best to go into flower with a healthy plant. Cheers

Does this look like leaf miner damage? There are small tracks on most of the older leaves similar to the picture.

Slight damage to one of cotyledons If you look at this picture you can see slight damage to one of the cotyledons, I don't think it's due to light as the damage is on the bottom side, maybe I watered it to much. Should I worry?

I gave an N boost to both plants but the one I haven't being using LST on is presenting an issue on the leaves, they are turning dark green on the inside, wondering if it's the true healthy color or is a sign of excess N. There are more photos in the journal Thank you

Garden visitor eating my fan leaves.This is my second grow (outdoors) and I need some advice. Saw some holes on the SSH fan leaves. When I flipped one of them over, I found a visitor that I think is a Spider Mite. The grow is looking good but I want to avoid any problems. How do I get rid of them?

Help! Droopy leaves still Should I go ahead and transplant to larger pots? These roots were long before I put them in these less than a gallon pots (all I had at the time) they’re still droopy after transplanting them on Friday. Afraid the pots too small for how long the roots are from the clone machine.

Dry spots on sugar leaves, plant late in flowering, also spotted on another one in the same reservoir Hi guys, my plant is around 2-3 week before harvest. What is the cause of the these dry spots on some of the smallest sugar leaves on my plant? The ppm might be too much and is around 1200-1300ppm. PH is 6.0-6.1 I've spotted it on one other plant in the same reservoir. Thank you

Dark spots on leaves forming So this is two separate plants I've got brown spots forming at the top. They're both about 4 weeks into flower. Watering every 3/4 days (4/5 litres each) with nutes. Humidity around 50% 26 degrees day time around 20 at night. Any ideas?

Nitrogen toxicity- dark leaves Seems I might have nitrogen toxicity? Growing in ffof, 38 days. I thought the dark green was a sign of health, I’m a noob. No burning or widespread yellowing tips, just dark green. What to do? I assume water the hell out of them? I assume they will recover quickly? Thanks

Minor discoloration on seedlings (nitrogen toxicity?)If anyone has advice on the middle plant, I'd hugely appreciate it. I added nutrients last Thursday (7 days ago) and I am pretty sure it was way too early. The middle plant has some discoloration on the leaves. Will avoid any more nutes until I transplant into 5 gallon smartpots.

Copper spots on mature nodes. Day 64 I am seeing some copper colors starting to come out on some sugar leaves near my more mature bud sites. Started today on day 64. I have been following fox farm nutrient schedule and watering every 3rd day with PHd after adding nutes at 6.2. Is this normal or a nute problem?
