TweetNLstarted grow question 6 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 ! 🚀

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Rusty spots mid-top of plants. A couple on each plant. Thoughts?(Check diary for more details)
Thinking calcium deficiency, also maybe magnesium deficiency on a few low yellowed leaves. Thinking it could be nutrient lockout? Feeding them 6.25 pH always. Gonna try 7.0 once and 6.5 for awhile. Thoughts anyone? Im still fairly new and learning

Leaves turning yellow with brown patchesI noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

Is this turning purple from temp changeSo it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Light green patches on many leavesHey, few days before I noticed light green patches on leaves and now it's visible on more leaves. I noticed it only on large leaves now.
What can be a cause of this?
Also, I underwatered plant these days and maybe this can be a cause?

Unknown rust on 7th flowering weekThis started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?
