It's a normal thing and it's good for you : it means your babies are eating nutrients, which tends to decrease the electrical conductivity. I'll be around, happy growing bro!

Yes the soil is absorbing some of the nutrients from the solution effectively filtering it

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!a year ago

Remove leaves from auto?Should I remove fan leaves from my auto flower? I wonder since it is so crowded, I worry a bit that the leaves are pressing against the buds. But maybe that isn't a problem? I've read that removing leaves is unnecessary and stressful for the plant.Week 9

Northern Lights Auto, quite short and bushy, fan leaves shielding light - should I defoliate?First time grower with a quite short Northern Lights Auto in week 6. The fan leaves seem to shield a lot of light from the inner leaves, also touching ground. Should I trim the fan leaves? Or should I keep them, since it already seems stressed enough for it's short life…Plant. Too short

the pistils are turning orange and the buds are small, maybe not enough room? Too much PK? Is it really a serious problem? What can I do? Some advice?Buds. Not fattening

Some guidance for ScrOG please@22cm & preflowering for about 4-5 days. Haven't noticed any stretching (~2-3cm)
When do I start with the ScrOG and at what height should one set the net ?
Also curious about defoliation: Right now, I keep tucking the fan leaves under the smaller ones.

Defoliation (no horizontal room in my tent and a lot of vertical room)This may seem like a dumb question but is cutting these small lower branches off going to promote vertical growth in my plants? I will be doing it later on anyways to eliminate larf but would it be more beneficial now or is it worth to keep to take in light energy for nowTechniques. Defoliation
