PH drop from 5.8 to 5.4 over night every night
PeppaWutzstarted grow question 3 years ago
Watertemperature 22 °C, 100 L reservoir (changed every week),Start EC 1.0 and drops to 0.8 at end of week, Ph adjusted daily to 5.8, tent temperature day 27 °C and at night 20 °C, humidity 55%. I add calmag to EC 0.4 and canna aqua until EC 1.
Why does my ph drop over night?

GMSgrowsanswered grow question 3 years ago
Your ph is dropping due to your plants up taking more water than nutrients. It leaves a higher concentration than when you first mixed. If they were taking more food then your ph would drift up. I used a growboss ph & nutrient meter for constant monitoring when I grew rdwc. Try lowering your ph to 5.8, that is the sweet spot for veg. 6.2 6.3 in flower. Cheers

Wilted leaves during mid to late bloom.Hi, I skipped watering yesterday and the leaves were wilted this morning, gave 4,100cc nutrient water this morning. My question is how much will this set the plant back and can I expect to salvage the crop? Thnx.

When to start flushingShould I stop adding nutrients and just give the plants plain water now? I'm in Week 8 and many of the FastBuds Pineapple Express Auto grows I've seen harvest around week 10. Would switching to just water be a sufficient flush?

What is happeningWhat is happening? Northern light was to cramped but could not move it so the photoperiod plant dominated it. I just put it under a led 60 spot light. This does not look at all like my other Northern light. Thanks in advance and will it give me anything.

Seedling in TroubleI have a seedling that is alive but has not popped its cotelydon leaves open yet. It almost looks like part of the seed might be stuck and holding it back.
As it stands now, I'm thinking I should just leave it alone and give it a chance to finish the job.
Recommendations?
