what is this

Im new to using led and never really had a plant problem before . Im wondering if this is nute burn or def or bleaching or what I can do to fix it

Looks like a phosphorus deficiency. Could be a lock out issue. Not sure what method of growing your doing but if soil/soiless hand watered, flush the media then feed. If Hydro check your TDS/EC/PPM and see what that and your pH is.

Also, it would be easier to tell if we could see the entire plant.

phos def add more phos. In a tea would be best and will have faster results.

O im using soiless mix with general organics go box 5 gal pots I will get better pics

Why would u flush if its def

Nutes need to be in balance. Less is more.....
It's a reset of feeding.

I would feed with just water for a week or two.

Ya I never really flyshed before with organics . I noticed my 5 gal pots take forever to dry up too so ive been watering very little

Looks localized.....I wonder if you have root aphids or some other kind of bug.

General organics is not organic. Still salt based. They lie. There's chems and heavy metals in those bottles.

What does localized mean .

building your own soil. Cootz mix, super soil , etc...

localized means confined to that plant or area. Basically pests are not jumping ship. Staying where they're at.

Only on a few leaves, not all over the whole plant.

And definitely a deficiency as Hyroot and I both initially suspected. The flush I recommended, as tenthirty explained is to essentially start from a clean slate. You then know what's there because of what you added. Plants do not assimilate nutrients all at the the same levels and so overtime you can get salt buildups that will re-suspend in solution upon watering and throw concentrations off causing other nutrient problems even if pH is good. Looking at the pictures it appears you need to bump up your feeding all around. I'd increase buy 25%. So if you use 8ml/gal 25% increase would put you at 10ml/gal, 8*1.25=10 or (8*.25)+8=10. See how that does. If a little burn, back it off to ~12% so again if using 8ml/gal go to 9ml, (8*.12)+8=8.96. If 25% seems fine and they still have that pale appearance go up a little more and find what they like. Some plants are heavy feeders while others are not, just as some are more finicky than others.

Thanks guys ya I havent been feeding to muxh mainly because my pots wont dry out for me im used feeding under 1000w in a 4x4 still trying to figure out how to water/feed with led

If I make my own soil I would just water

Is it possible for the light to be causing this . I noticed one side of the second plant was getting the same look a little but they are under seperate lights and I switched the plants around and now the second ones starting to show similar symptoms . Cause ones under a hans and the other is under the panel using illumitex leds

And is 21 to low for temp .
