New sudden Leave discoloration helpppp

Crumbzjr · Aug 29, 2022

Any ideas wat the discoloration on the leaves could be? This has just happened within the last week or so , plants have been perfect until now.

Strain is ice sherbert, 2 plants both experiencing same symptoms.lights and temperature have been controlled pretty well thus far, about 3-4 weeks into flower now and just noticing problems. Have been feeding with fox farm nutrients every other time plain water, I have been very conservative on the amount of nutrients i am using. I am thinking it’s a phosphorus deficiency but looking for opinions as this is my first time growing

what you growing in and how much you feeding them?
your probably right with your diagnosis!

They are hungry. The lack of nitrogen is hindering photosynthesis and therefore your seeing anthocyanins prematurely. usually you want to see this in the last few weeks.

make sure you have good drybacks and feed a bit more… maybe feed feed water.

I'm with Nick on the Phosphorus, four weeks in and they look like they're trying to finish flower.

It’s growing in fox farm soil and using fox farm nutrients. Thanks for the input , I jus watered them this morning and gave them nutrient , usually this would be a time when they get plain water but they are clearly hungry. Will they come back noticeably or will these damaged leaves stay this way? Also what should I do going forward? At 4 weeks into flower I guess I should have started feeding them heavier regardless

Purple stems sometimes indicate a magnesium deficiency. Wild temp swings will as well. Why do you have them on just plain water at this point? I go to plain water the last two weeks of flower.

They should green up a bit if you feed adequately but the and plants dont really waste energy fixing leaves they ise it to grow new leaves

I’m giving them plain water every other time, but I’m going to start feeding every time for the next few waterings. Also these plants have had purple in the stems since I got them as clones. It was a concern to me from day one but I assumed it had something to do with the strain

The purple stems are not to much the issues i see. Its the light green and yellowish leaves showing purpling in the leaf tissue and not just the vein’s. Thats caused by lack of nitrogen combined with high light

This is not a bad thing just a bit early to see in terms of flowering time and a sign you wanna bump N a bit until closer to the end of the grow

Thanks for all the help. Gonna just feed them more and hope for the best. I will update. Thanks again.

Maybe back off the light for a few days to reduce stress and give them some time to adapt.
