Clipping dieing leaves question

[mage]

Hi

Any input would be appreciated to do with this question.

I was wondering if it is a good idea clipping off 'dieing' leaves. My plant is recovering from light burn and being underfed. I think it is also having some issues with temp atm.

The new growth looks great, however some of the older leaver have turned completly splotched and yellow (removed) and the set of leaves above is starting to go down that path, as you can see in this photo

Is it worth clipping these problem leaves off or waiting a couple of days for them to turn yellow.

Thanks

IMO it matters less whether you cut or not. Correcting the condition will most likely cull affected leaves naturally. If the same condition exists, cutting may accelerate symptoms to other parts of the plant. I usually cut em when laying on the medium or otherwise in the way.

Myself, I let the plant tell me when to remove any yellowing/dying leaves. I do so by wiggling the dying leaf around with my index finger - if the plant is ready to shuck it, it will fall right off. If still firmly attached, it is my opinion that the plant is still using that leaf.


Peace

Hello I am by no means pro but I agree that correcting the underlying problem will be your answer....cut the affected and it might accelerate to leaves currently unaffected. I also let leaves fall with a slight "finger wiggle." I have read in the past that letting yellow leaves stay attached draw energy from the areas you want it to go....main stem, etc... But I haven't tried it out. Good luck bro!

IMO, supply leaves are more self sustaining and contribute to overall growth. I cull in case of mildew etc. I've got a small grow and often cut em for better space or air circulation.

Other than that, ragged supply leaves are common. Especially with unknown genetics. A pampered indoor environment might not need the reserve capacity of primary supply leaves. Knowing a particular strain means knowing whether cutting fans will stress the plant or not at all.

I have the pampered enviroment...I just need to work with a certain strain consistetly to find the best grow technique. I cull for mildew and circulation but nothing too extreme.

I think your best bet may be to wait until you have some healthy foliage appear. It may take a little time as the plant recovers, but will mean as you slowly remove old dying growth, you will have new growth to take its place. Be patient though.

If you start hacking away now, it could mean more stress, which means you could do more damage. Wait until some healthy useful leaves pop up. So solve your light, temp, and feeding issues first. And let the dying leaves fall off, or take them when you have healthy growth.

If you have light/temp/feeding issues maybe its time to go to the drawing board regarding your space? Those are 3 major factors in your grow. It only looks a few weeks old tops, so maybe even start a new plant off? While your current plant will recover most likely, major stress through a plants life can cause irregular plant effects, including hermies, and stunted growth. If you have clones should be no biggy, seeds would be a little more time consuming though.

Whats your set up, as far as lights and grow space?

Hey Moot thanks for the response

I think you're right with the issue being light/feeding/temp. The original issues that caused the scaring were light burn and under feeding, which have since been resolved.

It's clear there still is an issue from the way the edges of the leaf fold up, and by how the leaf does not "flatten out", it stays crumpled in the middle of the leaf.

I dont feel it is light as i upgraded the 400 watt 6 year old (a friend lent to me) bulb to a brand new one and set the distance to around a foot and a half (i think 45cm).
Originaly when i put the new bulb in i lowered the light too low causing light burn.

I think i can rule out the temp too. The canopy temp is around 25C/79F. The res temp fluctuates from 21C/70F in the morning to 24C/75F in the afternoon. We are in autumn in this part of the world so it doesn't get too hot or cold.

My space is 3ft by 4ft. I have constructed a woden frame that goes to the ceiling and wraped panda film around it. The space is open at the top and bottom. I have a rotating fan inside blowing air on the plant 15 mins every hour. I also have a 6" fan ducted from the grow area into the roof. I think it's fair to say i am giving the plant decent ventilation and space.

My system is a waterfarm type system where i have a top bucket full of clay balls. The plant sits within it and has its roots grow and drop down into the bottom pot which has 4 airstones in it conected to two air pumps. The roots just dropped down into it today

The new growth is looking better over the last couple of days. I was using two water pumps pumping water to two drip rings, one under the rockwool rube and the other above sitting on the clay balls. Two days ago i turned off the drip ring sitting below the cube and the new growth is looking good, so i am hoping it was some sort of feeding problem like this.

I way under fed the plant leaning too far to the cautious side, however my feeding schedule is back on track.

When did the problem start? Pretty much the day i transfered into my system.

I changed the light since then and i am still getting this issue so i think i can rule out light being a possible cause.

I only had my 6" fan on once per 2 hrs when i transfered into the system, since then i have switched it to 24/7 and added a rotating fan. So i think i can rule out this being a possible cause.

Temp wise, the ambient temps havn't changed since prior to the system and my temps are not outside of the limits of what will cause you a headache.

Feeding however has been all over the shop since transfering into the new system. So it could be an issue with the nutes + additives conflicting or a problem with the delivery. I feel it is the delivery as discussed above.

Anyway i want to give it a couple more days for the current set of leaves to develop to see if the new growth is better before altering another variable.

Unfortunatly this was my last seed. It is however bagseed so meh. I have a friend who managed to get a hold of some purple haze (i think its called that) seeds, so i would like to get my system nailed before growing some good genetics.

I am hoping that this plant isnt a hermie. I have little doubt that it will recover. By the looks of the preflowers it appears to be a male though. Having no seeds left i would like to follow through and flower it as having spare viable seeds is a definite plus for me, and i want to get some pruning practise before growing with good genetics that are hard to get a hold of in this country.

Many thanks for your input +rep

I don't know if I can post this here, but I have it in my favourites. Its a leaf diagnosis page with pics, and descriptions. Super helpful! Shows many leave conditions and what caused them.
