My buddy has a problem. This is an outdoor grow.
Each year for the last several years, my friends plants Veg great. No Problems. Beautiful, huge 7ft tall 4-5 feet wide Mr Super Silver Haze. Weve been running the clone mother of this plant, inside for 3 years, and its as good as it ever was.
My friend made some seeds from F2s from this plant I made, and we have also grown at least 25 out inside and never any purple/black.
He then crossed my F2 with his 1988 NL1/HP x Hawaiian/ 88 NL5/Hz x 88 NL1/HP x RKS.
I grew 1 of these inside, and it did the same thing, and I NEVER have a PH problem. I use Promix BX. Mine also vegged normally
When they start to kick over into flowering, the growing tips, start turning Black/Purple... and not in a good way. This aint the normal purpling ect. It is totally deforming/disfiguring, and ruins the plant.
#1 my friend doesn't use lime, he should, but has been growing 35 years, and never had to use it, and has never had this problem. The new forming buds/tips/leaves look like the plant has bud rot. But like I said. I ran a tester inside, and it turned Black
I'm still guessing that its some kind of nutrient lockout, or it could be that his NL1/HP has a virus that's passed on, and not visible until they start budding.
Ive told him I think it could be PH/Nutrient lockout problems. Could it also be possible that it may have a Calcium/Mag/Phosphorus deficiency because No Lime PH troubles ect??? Causing deformation ? I'm also sure that more nutrients are locked out, IF PH is the problem. Hes also yet to run a PH test.
Any Ideas ???
But I'm still skeptical about PH as I said, I ran 1, and it turned black, and my PH was good.
