Light stress?

HobbitGDFstarted grow question 3 years ago

Ok so these girls seem to be getting lime green 2 yellowish. I was afraid it was the light, so I backed it off a little. It's at 26in and 55-60% power. If it's not that could it be potassium? I didn't use the 1st step in the dry amendments.

A Nitrogen (N) deficiency by the looks of it, check the pH and make sure it's in optimal range (5.5-6.5/6.0-6.5 in soil) to prevent nutrient "lockout", and increase the Nitrogen based fertilizer (usually labeled as "Grow" or "Veg") by 50% since it seem pretty severe. Check the plants daily to see how they react to the different diet, adjust your fertilizing accordingly! Hope this helps! Good luck and happy growing :)

Well I'll never not use base again. The ones I used the base on are perfect. Shame i fucked this grow up from not following directions. They just needed more grow nutes. Potassium, boron, nitrogen, cal/mag. They suffered but they still are swelling up. Thx everyone

Maybe heat stress but they show no light stress - for me.. I would also check watering (water measurement from your distributor online...i have to add cal/mag...) and add more grow nute. Peace and fun!

Is the filter maybe filtering out calcium and magnesium? I adding cal-mag to my plants with the exact problem along with upping the grow nutes and it worked. My two critical purple are two different phenoms; one has much darker shorter broader indica leaves well the other has long light green sativa leaves.
