Thanks. But why would that cause the leaf to go pale ? I understand the burnjng tips from it. Just not the pale yellowing of the leaves. Humidity stays around 30 is that too low?
Any chance it could be light burn since it stays 84f in my cab
temps are ok if using co2 but as long as a fan is blowing around you should be ok. hell lift it an inch or three just to see.. most budding is done in dark anyway
Strain is purple kush auto. I have two. One is nice deep green with just the very tips of random leaf burnt, the other is yellowing with about every leaf tip burnt. Week 4-5 dont think its end of life yellowing. Ive chalked it down to my humidity staying at 30, or light burn. If used as recommended, osmocote dont normally burn. Idk .guess what is comes down to is wondering is its light burn, thats what i really want to know. Here is a pic of the darker green one
Slight heat from the light being close. You fixed that.
Not necessarily, that can also be nutrient burn, says the girl who runs 105 canopy temps all summer long
I'm with nutrient burn on this as well. I usually run my nutrients up until I see tip burn then back off about 10%.
High P.
Research osmosis. Once your soil becomes hypertonic the plant will stop/slow the uptake of water/nutrients then begins to transfer nutrients from the leaves to the new growth. You need to get the plant transpiring again. Clear your medium of a good portion salts but not all. It will take 6-10 days before you start to see results, if you get impatient and feed them to soon you will be back in the same boat your in now. If you don't have an EC meter buy one. Never feed over .5EC or on dry soil.

Yea just increase the ppm's in your medium even more that's sure to fix it.
Just curious, what strain is that. It looks like it has tremendous potential. Pretty too!
Purple kush auto. I also dont feed. I keep it very simple i mix 1 gallon peat/perlite mix, add 1 tsp lime, 1 tsp epsom salt, 1tps osmocote plus, which is guaranteed to now burn even at 4x the recommended dosage. I honestly just hope its not light/heat related.
