I’m not sure without pics or a diary here.. my guess is maybe you have some lockout issues or something. If the EC is coming out the bottom substantially higher than you are putting in, there’s likely excess salts in the medium.
I would go with the flush you were thinking about. At this stage it’s good to flush all the excess nutrients and salts from veg out of the medium.

I feed with PH 6.5 and EC 1.2 so why PH dropped like that ?? My tap water after 24h is PH 7.5. I will try watering with that PH without nutrients . Is it a good idea ??

Week 9 auto discolorationThis week 9 double grape auto by Mephisto has had some issues with lower fan leaf color for a week now. I’m a first time grower so still getting the hang of all the ins and outs, I checked PPM runoff and it is around 800.

Brown spots and leaf discolourationCan someone help me identify this problem? I thought it was CalMag, but have since fed it with a CalMag solution and it seems to be getting worse, mostly on one side. It’s 30cm from an LED light as suggested in the instruction manual. The other plant has no problem like this.

Leaves are getting yellow.A few leaves are getting yellow. I'm using fertilizer only once a week, perhaps I should use it more often? I want to make sure it's a nutrient deficiency before I start using fertilizer too often and do more harm than good. Two are bottom leaves, but two are top leaves.

Harvest Time?2Stunted Autoflowers
Top Cola seems ready, though lower bud sites are still underdeveloped.
Seems there's lots of amber, though maybe still cloudy.
Should I wait until the lower buds develop and risk degraded THC, or harvest now?
Any help would be great, Thanks

Leaves turning yellowMy plant was growing great until 3 weeks ago when it’s been very hot and humid. It’s Northern Lights in a fabric pot on my deck and during this time I might have watered too much? The buds looks ok but the plant is now kind of a light green and leaves have been turning yellow.

Recoverable? Cut Around? No harm done besides yield?Heat stress plus some kind of lockout due to topsoil drying out. PPFD set to 900 for 2 wks, + dried topsoil. Lowered light intensity, flushed with water. Color has mostly returned. Sugar leaves affected. Is this fine, recoverable, dangerous to smoke?

Yellowing leafsI’ve got a bit of a slight concern - using BioBizz nutrients, I’m on week 4 of flowering and I’m starting to see a few of the lowers leafs going yellow (normal as it’s using up the nutrients stored) but should it be happening in week 4 of a 8-9 week strains?

Leaves falling offPlants are about at transition from vegetative to flowering and I'm noticing a little more leaf shedding than earlier. Leaves are turning bright yellow and falling off. Mostly the inner leaves that are shaded by the canopy. Overall the plant looks healthy. This normal?
