Hi All, start with posting my plant details.
grown in 7 gallon smart pots with FFHF, mixed with some dolomite lime only as the PH starts a bit low. Growing with 1000w LED. RH between 40-50% for flower. 2 6” fans blowing. With 6” exhaust fan running.
have been watering with PHd tap water adding only some Cal Mag for veg. In flower, I’ve been adding a little cal mag and 1tbs of blackstrap molasses/gal per water. Watering about once every 3 days with near 0 runoff each water. Really haven’t fed the plants very much, as the plants aren’t super big (21 inches) in 7 gal pots.
just the other day gave some dr. Earth bud and bloom booster as a top soil treatment
Plants grew without any issue most their life, no burnt tips or clawing pre-flower. Starting around week 3 or so of flower, starting to see some different symptoms.
1. Clawing of leaves
-appears like a nitrogen toxicity. Makes sense since week 3 of flower or so, plant not needing as much nitrogen. Confusing as I haven’t been adding nutes to soil.
2. Burnt Tips -appears like over fert. Also strange since I haven’t been adding nutes, the PH also has been measured whole life, always within 6.2-6.8 and no burnt tips in veg
2. Brown spots on leaves below sugar leaves -
Almost appears like a nute deficiency, like a mag deficiency or manganese deficiency, small brown spots closest to the stems of leaves primarily below the sugar leaves getting a lot of light. Strange as I have been giving some CalMag throughout grow and Ph from 6.2-6.8.
The plants don’t look too bad but I had really thought I nailed growing conditions, which is why I’m confused around these symptoms.
Nutrient Lockout? Since I didn’t really add fert I didn’t think I would get nute lockout. Looks like maybe too much nitrogen in soil or sensitive strain is locking out Mag/Manganese?
I was attempting a somewhat organic grow seeing that the plant would get whatever nutrients it needs - possible that FFHF just isn’t a real organic soil that can build the correct life for an organic system - and maybe has too much available nitrogen in it that’s locking out other things.
or could it be that the plant has used up the nutrients in the 7 gal pots and actually is facing deficiencies? Maybe the clawing could be from too much air movement with a small tent? Seems worse around the walls where the air flow would be higher.
