Is it better to adjust nutrition if using soil from a previous grow?
One of my grows is nearing the end and is being flushed this week ready for the chop on Saturday. Do I need to adjust the feed schedule for the next grow to account for any residual nutrients in the soil from the last grow? I am using BioBizz Light-Mix soil & full BioBizz range.

Water and nutrients
I water every other day. So far I have been using nutrients to bring my water up to the proper EC (ppm). It is always a VERY small amount (1/2 tsp). I haven't noticed any signs of toxicity but I wanted to hear your opinion of my approach and changes that I could/should make

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

How to decide when to start flushing
Do I look for specific signs? Or just go with the breeder's info sheet (7-8 weeks flowering), I'm thinking to keep feeding for 1 week more, from what I can tell, trichomes are still mostly clear, and about half of pistils brown.

Earthbox/SIP flower nutrient delivery method
7 weeks in plants seem happy. Should I top dress with dry amendments for flower now to be preemptive? Since I do not top water and use a SIP container, does top dressing even make sense when done early - or a waste? Figure they will need some P and K soon. First grow, TIA!

Is it possible to "overwater" pure coco (no perlite) ? Is it ok to not water them for a day ? As my pot stays heavy and the leaves show signs of overwatering. The plants are still young autoflowers

Time to start 2 week flush?
Hi 420 Fam. So I would just like to get your opinion on my 3 White Widows. Only SOME brown/slight yellow orange pistils here and there. Tomorrow (26Aug) is start of week 8. Should I start flushing tomorrow to have full 2 weeks, or do these look like I can start flush from week 9?

Should I flip to flower
I think it might be time to flip to flower after this cycle of nutes is done, as the the two bigger plants will just end up covering the runt plant in top right corner if I let it veg to much longer, what does everyone think?

Brown Tips on Leaves
I've noticed some brown tips starting to show on my autoflower plant -- the Auto Blue on my page. I personally believe it's from overwatering barely, though I have solid air circulation and try not to water until the soil is truly dry. Any help would be appreciated!

Hi. Is it worth putting my 5 in plastic pots into their fabric pots ?? After all the advice I’m going to try doing one day where I feed them, next day light watering, 3rd day, water to run off then start again. Strange because when I didn’t feed for 3 days, they came on better
