I am having some issues with my CBD plants. I have 3 of them in the room with 13 other plants. The other plants are a Lemon OG and they are doing great. Everything is on the same water and feed schedule.
I pH my mix and I keep it between 6 and 7. My water is high so it's always acid, never base. The bloom booster I use takes pH down but I still usually need to add pH down to get it where I want it.
I jump around between 6.2 for the Cal Mag to about 6.9 or even 7.
I feed 1/2 dose of Fox Farms Big Bloom (supposedly organic) and 3ml/gal of CalMag each time I water. This has been pretty regular for several years and seems to work for most. If I get a light eater like Satori, I cut back a little but if I get a heavy eater, I use the bloom boosters to make up the difference. Although, I have been thinking about trying a new nute and a new routine, this has been pretty solid for a few years.
And, like I said, the rest of the room, other then the CBD plants are doing great.
So, obviously this no THC ditchweed hemp plant is 'sensitive'. LOL
I often have some yellowing of the fan and secondary leave as flowering progresses but these plants started to yellow early. They are in week 4 and one is still green but heading yellow. One is yellow and the third is dying with crusty spots.
This looks like classic pH problems to me.
It's hard to tell from these pics but most everything is green. Even the buds on the CBD plants (3 on the right). It's the fan leaves and now the second leaves turning yellow. And, that one pheno has the crusty spots.
Oh yeah, these are 3 different phenos. My clone mothers.
I don't know. Doesn't look good. Love to hear any comments.
Sorry about the yellow pics. Another reason to go LED. LOL
