Hello, im in a tough spot about 4 days ago ago i treated a plant for boron deficiency with boron powder (4 tea spoons x 4 gallons) and 2 or 3 days after i saw my plant curling most of the top leaves and spreading down. Also the tips are starting to crisp because of chlorosis between the veins. Im at the second week of flowering phase and im needing some desperate advise.
Thank you very much in advance!
you could try a foliar feeding of a mild Epsom salt solution (MgS04). had a similar problem with the chlorosis and crispy leaf edges and it seemed to help within the week. all the new growth was healthy. the other stuff never really recovered but the new growth never showed signs of deficiency.
hmmmm i will try that in the morning when the lights go on again, ... but in my case it was the top leafs that where the most affected.
this is the first time i grow and i know i have to be patient to get results but i dont know in this case whats happening and i want to correct the damage before it can damage my bud yield.
So if someone else has any suggestions please it will be of great help
The appropriate level of boron is a pretty thin window and not the biggest concern when it comes to addressing deficiencies. What you have now is way more damaging, it seems. I think your old growth is boned for sure. Try the epsom foliar and a lil flush before returning to normal feeding.
