itchylemon Posted October 20, 2021 Share Posted October 20, 2021 Hi all, this is my first grow so please bear with me if this is an obvious one. I've done a search of some threads on here but not finding anything that looks quite the same. Basically, I noticed some weird patches on the leaves on one of my plants this morning. The plant looked absolutely fine yesterday. The problem seems to be localised to just the first set of 3 tipped leaves. At first the patches were just a lighter green, and now they seem to be browning. My thoughts are that it's either some kind of pest, in which case I'm tempted to remove those leaves. I've separated this plant from the others just in case. Or that it's a macronutrient deficiency since it's showing up on older leaves first. Currently feeding all my plants the same concentration of Bio-Grow (Bio-Bizz range), but this one gets less because I water it less (due to the plastic pot). I'm due to start giving it Bio-Bloom and Topmax from the next feeding since it's starting to form pistols. Any thoughts? Quote Link to comment Share on other sites More sharing options...

The other plants which have had the same treatment are all doing great, but they're in fabric pots and get watered (and therefor fed) more often. For interest's sake I just checked PH, which seems to be somewhere between 6 and 7. My probe isn't super accurate and seems to also give different readings depending on how deep it's placed.

PsyCLown Posted October 20, 2021 Share Posted October 20, 2021 Did you possibly spill some nutes on those leaves? 1 Quote Link to comment Share on other sites More sharing options...

I normally give the leaves a spray to wash them down after watering but may have forgotten to do that on this plant yesterday bacause it's schedule isn't synced up with the other plants. If I did spill, it would've been diluted nutes that I was watering with. Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted October 20, 2021 Share Posted October 20, 2021 Ja like Psy said possibly nutes. If it affects more of the plant worry. I would water the plants all the same if I was you. Just less for the ones in the plastic pot. Consistency is key. 1 1 Quote Link to comment Share on other sites More sharing options...
itchylemon Posted October 20, 2021 Author Share Posted October 20, 2021 Got ya. Thank you both for the input. Will keep an eye to see if any more leaves show worrying symptoms. 1 Quote Link to comment Share on other sites More sharing options...
