The info in this thread is wonderful... Thanks to
kokua and all who contributed to this thread.
For the longest time i thought the damage i was seeing was due to the leaves being splashed with water that was pH'ed too low (i had a faulty pH meter)...because only the lowest leaves had the problem. The silver patches looked an awful lot like deposit on the leaves...like spots one might get on glasses from not using Cascade in the dishwasher. The "deposits" didn't wipe off, so i then assumed that they had been burned with acidic water...but it was Thrips...the little f*ckers!
I order spinosad online last week...hopefully it arrives today.
My previous indoor grow ended in failure and now i know the real reason why. On my previous grow i flipped the switch for Satori, Sadhu, and Purplicious on Aug 1st. Two weeks later i went on vacation for 18 days and returned to find
badly damaged plants. At the time i though it was a combination of a faulty pH meter, and a inexperienced friend who over fertilizing the plants. The plants all looked to be severely Nu+ burn. The Purplicous could not be saved, but the Satori and Sadhu were removed from the cabinet, flushed repeatedly and then put outside to heal (still thinking it was nute burn).
I now know that it was THRIPS that destroyed the last grow, and that in a late stage of infestation the plants had brown, curling leaves, that were brittle.
Here's a picture of the surviving Sadhu from the last grow. It's not a great picutre, but i think you can still see that there are no fan leaves left on this plant...it lost them all thrips. The plant essentially stopped growing, the bud matured, but the plant is tiny compared to the clones in have in the cabinet now which are three times the size and in smaller size containers.
...the only leaves left on the Sadhu were ones that have trichomes (see belwo). Mandala seeds describe Satori and Sadhu as being somewhat mite resistent...and i guess the same can be said for thrips. It suffered a lot of damage, but survived. The Purplicious (not a heavely trichomed plant) all died.
Here's what's going on right now...
I've got 8 plants in my cabinet (some on Day 42 - Satori and Sadhu, and the rest Casey Jones and White Satin on Day 27). There's heavy thrip activity and i've already sprayed with neem - twice. I'm now waiting for the Spinosad to arrive in the mail, but what do you think i should do?
The general consensus seems to be...don't spray Spinosad on flowering plants...would it be OK to spray the foliage and avoid the flowers?
I'm a little nervous just spraying the vegging clones and leaving the flowering girls to finish given that i lost 50% of my crop the last go round...
Thanks in advance for your thoughts...
peace,
