I have been trying to solve this for awhile now with no luck. Details and pics below.
Plants seem to be getting worse. Problem is affecting mainly the TOP and MIDDLE of the plant as well as new shoots. Top leaves are folding in so much that they look like peas or little skinny green bananas.
Temp is about 78F w/ lights ON and 70F with lights OFF. but when this began, light was likely too close to plant. But this has been corrected, so why are new leaves still showing this?
Humidity is 35% - they are in veg.
400w MH
coco with some perlite mixed in,
nute regimen is 0/6/9 - used to be lucas formula (0/8/16) General Hydroponics. About 900-1100 ppm.
pH going in is about 5.2 - 5.5
Watering once a day, nutrients every 3rd watering.
I uprooted the plant and the roots look very healthy. In fact, the plant is root bound. It looks small for the size of the rootball.
The waxy coating on the leaves is gone. Not only do they feel dry and thin like paper, but they don't have the usual weed smell. In fact, they kind of smell like button mushrooms (little white edibles). Leaves aren't sticky either.
Would that be wind burn? If so, is that recoverable?
This MH bulb is near a year old now. I have a new HPS for flowering, and wanted to finish up veg with this MH before replacing it. Do older bulbs give out more radiation/UV than newer bulbs?
