TweetNLstarted grow question 5 years ago
Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air?
I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.

Hi Tweet, great grow , really healthy throughout ! What I think happened is that the lamp to plant distance is a bit short so the top of the plant reacted to that. you can see the top leaves cupping from the heat and the stress, and that's where the browning is coming from. Adjust your lights higher to deal with the heat and light stress and it should recover quickly. Hope this helps ! 🚀

Dry brittle leavesDiscoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

Brown spots on yellowing leaves close to Flush and HarvestI'm at day 69 of my grow. The plant has been getting frostier and frostier, the leaves are starting to yellow, and I'm seeing the first signs of amber trichromes. Today I noticed the leaves are starting to get some brown spots. Should I be concerned so close to final flush?

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before
Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Brown spot on leave. 6 weeks into flowering. -Temp 27'C day 25'C night- HD 65% day 75% night . Soil PH 6.5-7.00. Water always at 6.5-6.8ph.I just flush it 4 days ago because I think it got calmag lockout since I always give them around 5ml of calmag every watering. I only water when 2inch top soil dry with 1.5L of ph balance water. Not a fungus or anything that grow because It cannot be rub or remove from outside.

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.
