Damaged leafs
Zukyyystarted grow question 4 years ago
Hi guys! I have a flowering Northern Light with several damaged leafs, as you can see on the pictures. Are they deficiencies of some sort? If so, what do you think can be the root cause? I use only filtered water and the RQS easy boost mixed with the soil since the beginning. TY

ah, missed it's a slow release thing... that's the problem with those if not precisely mixed... and a one-size-fits-all doesn't really exist for all strains. Irrigate with a little extra runoff in that case... don't stop. Likely lasts till end, but do react if it improves.
i wouldn't try any aggressive flush, unless someone has experience where that helps... will cause a lot of negatives too. If things are developing seemingly well, don't rock the boat too much this late. more likely to cause more harm than good in many contexts. sticking to ph-only for a while is conservative and safe.

looks like toxicity - the dark/glossy leaves... Ca/Mg spots that are more likely lockout due to high P/K.
Give it regular irrigation as you normally do, but no fertilizer for a while. I wouldn't wait for any yellowing, but once they look a healthier green resume light watering before your end of cycle habits (flush or not)
One thing to consider is that you are day 50 into bloom? Senescence does different things with different plants at times, but you'll know better wtih a real-life look at leaves.. are they dark? bit glossy? just in case photos are deceiving me. if so, it's 99% certain a toxicity.

What should I do from here?I had some problems about a week ago. I investigated, and corrected at my best, but I am not sure what to do from here? Do they seem to get better? Should I do something different or just keep going as I am? - More pics and info in my diary

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Spots on leafs, and lime green topsI am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.

Discoloration 3 weeks into floweringDay 51 of my grow I'm starting to see some discoloration on otherwise healthy plant and I'm getting concerned. Most of the leaves of the plant are near the top. I cut back on my nutes on this last reservoir but the discoloring is still there. Any thoughts on what might be wrong?

Cat piss? Not the strain....So I've been having these brown spots, thinking bugs or aphids or.... but I spotted a neighborhood cat around our yard today, marking its territory elsewhere on the yard. Could this be cat piss sprayed on the leaves?? I wouldn't put it past this fella.... but not sure. Thoughts?

Leaf browning, yellowing curl one day change.Over night my plant went from looking good with maybe a calcium deficiency to curled leaves looking very soft and drooping. I sprayed with insecticidal soap, but in the past no harm. It is growing outdoors, 30c 60% humidity. Any help appreciated. I sprayed with kelp today.

White snipes on leaves... [ MAYBE THRIPS? SHOULD I USE POTASIUM SOAP? ]Hey guys! Do you think these are thrips?
The leaves have these white snipes already since some days ago.
Also, If you look carefully, there are micro white things on some parts in the leaves that could be the thrips themselves.
I'm thinking of adding potasium soap for this.
