Hi, if you are having such along growtime, its always good to do a Flus, a very good one with lukwarm water. If you are growing so long there are sltbuidups hanging on the roots and blocking new nutrients. The soil is getting very dense and its tough for the roots to handle. Give her anice flush to flush away old builitups and give oxygen to the roots.. she will love it. Aftr the flusing you can start new: that means give her nutrients and beneficals ( living organics, bacterias, molasses) to enrich your soil. Iam sur your girls will shine soon again

Hello If you will see my different tests you will see that my bubblegum had the same symptoms. It is a lockout of the one on fertilization it is enough for you to water several times with the clear water with a PH 6.3 that should be enough because your substrate must be saturated with nutrients Do not forget to remove excess water from the plate May the strength be with you 💪

MarcXLanswered grow question 4 years ago

Top leaves turning yellow is mostly a zinc deficiency. In soil, zinc is best absorbed by the roots in the 6.0 – 6.5 pH range. Zinc deficiencies are more likely to appear when using heavily filtered or reverse osmisis (RO) water to feed plants since any zinc has been removed or wrong nutrition was given. Do you also use bloom nutrition or only cal/mag? Zinc deficiencies can show up when the plant is having root problems or if the plant is overwatered, even if the pH is right and the zinc is there.

Looks like a nitrogen deficiency or a ph related nutrient lockout at the roots Is the cal mag all you have been feeding it? it needs Nitrogen potassium phosphorus iron etc etc etc I would recheck the soils ph and give them a feed

Late defoliation?I didn't pay as much attention to defoliation during veg stage as I would have liked, instead I kind of picked leaves out here and there all through flowering. Should I have left it altogether after missing timing or as long as you don't cause too much stress it should be OK?

Defoliation?Day 21 of flower, do I need to do any further defoliation? Everything looks connected to a bud site so I'm apprehensive about removing anything else. Afraid of running into PM at some point as weather gets warmer and RH rises. At 45-55rh now. May get a small dehumidifier soon.

Looking for pruning/defoliating tips I have several tented plants under 12 hour light and I am looking for pruning/defoliating tips. Pics attached. For one, should I take out some select fan leaves to let more light down?? Lots of branches, too, maybe prune some smaller ones? Thanks for your help! John D.

Near Schwazz Week 6 - Autoflower My plant grew massively the first 4 weeks, and leaves became jammed regardless of my training techniques. A medium defoliation, turned into a massacre! Growth slowed last two days - almost up to speed again. What will come of a near "Schwazz" in early week 6 (auto), in the end?

How much / often should I be defoliating?Currently on my 2nd grow. How often should I be defoliating? I did a big defoliation at the start of flower, but it seems like after a week they've grown it all back. I'm worried I will stress them out if I defoliate too much. Do I hold off a week or 2 before doing more?
