1st Indoor Grow

Wait another week. Top only if your plant looks healthy. If not then you can just LST without topping. Good luck.

At this point you should be wetting the entire planter so your roots can spread beyond the wet areas. Water as necessary. Cheers

Seems like the start of a Nitrogen (N) burn! kinda hard to see exactly which toxicity it is by this picture but your diary gave the answer! Leaves developing a dark green coloration while still in vigor were the clues. Try lowering your biobizz "Fish-Mix" to about 1.5-2ml/l and the "Bio-Grow" to about the same amount to lower the Nitrogen uptake. Also try lowering the Cal/Mag to about 0.5ml/l to avoid toxicity, it is a micro-nutrient and the plant does not need that much without showing a deficiency! Hope this helps! Good luck and happy growing :)

The Ts600 is only a 100W designed for a small space, if you want to check how far you can distance your lamp from the plant try lowering the lamp to as low as 8-10 inches (seems like you're in flowering so I'd try going with 8) and check you plant regularly, if she shows signs of radiation/light stress (foliage starts to fold and curl upwards starting from the top of the plant) then move the light 2 inches higher! Also don't forget that in flowering the plant needs more light to produce fatter and denser buds! *I started using the TS600 as extra lighting during flowering, I got it set 5 inches from my plants and they're doing completely fine! it all depends on the plant and what stage of growth she is in. Hope this helps! Good luck and happy growing :)

With a 20 liter pot size I'd say go with a 3.5-4 liter nutrient rich irrigation every 2-3 days or when the top 5cm of the medium is dry! Make sure there is at least 20-30% runoff (more wont hurt), check the runoff for pH and salinity (EC) to get a good idea of your soil fertility and acidity to quickly fix issues before any serious damage is done or to prevent them from happening. Hope this helps! Good luck and happy growing :)

Firstly, this is an excellent grow to date my friend. Space is clean, and plant canopy is beautifully even. The photos are gonna dictate my answer on this question. My only advice is that you're now in week 5/6 of flower. At this point the plant won't be producing any further fan leaves so what you remove, ain't coming back. Realistically, a plant in a controlled environment shouldn't necessarily need any fan leaves - the argument being that these are nutrient storage locations and storage is not required when the plant is provided what it needs at all times. In practice however, the appropriate amount to defoliate at any time and at what frequency is very much grower preference. The plant won't necessarily suffer when you take the approach that less is more (on both counts). The real answer to your question is that it depends on you and what you're comfortable with. If it were me, I'd run back every large fan leaf on the plant, get rid of anything else in the middle that's mottled or twisted as well. Might as well do it now as these are going to have to go in like a week or two anyway to maintain appropriate airflow under the canopy into late flower. Good luck - it's truly addictive and yeah - planning that next grow is pretty the game👍
