6 weeks from planting the seed, i germinated in the final pot to avoid any transplanting shock. So far its a beast of a strain, i think it's into preflowering now really started to stretch up in the last few days. My 2nd grow, so far so good!
Needed to take emergency action as the monster outgrew the the 2ft x 2ft tent, had to buy a secret jardin ds90, plant is a little shocked from the transfer but all looks good!
I have a lumatex ATS 200w led, I've it raised to max height but I've still only 10 inches of clearance from the canopy. It's flowering now and upward growth has stopped as buds are starting to fill out, will I be ok with this short distance?
it should be the height that best covers the area and hopefully enough power at that height to provide "max" DLI relative to environment.
it may slow down, but you definitely have a couple weeks of vege growth remaining (leaves and stem elongation).
if you don't singe pistils or bleach buds, you are fine at 10 inches. this sort of damage can sometimes take weeks to present itself from onset of problem. so keep notes of power and distance... observe plant and react when necessary. too tight node spacing, you probably need less light. too stretchy and you probably need more. So, observe what little vege growth remains as it will help avoid issues in late flower.
buned pistils will look like little yellow nubs
200 w in a roughyl 2x2 foot area is a bit overpowered, so i'd becareful at 10". i'd guess that will eventually show some light damage, even if not in first few days.
460 umol/s / .36m^2 = 1200some PPFD. over 18 hours that's potentially WAY too much light. you'd be good with a 12/12 cycle at 18" and 100% power, in that tent, i bet. So with autoflowers, you'll need less over 18-20 hours -- proportionally less relative to hours of use.
so, do what you gotta do, but any hint of light issues (damage or even just really droopy plants last hour or more of light cycle) and be ready to dial it back a bit. either more height or reduce power. both can work.
Thanks to everyone who answered my questions! I checked the ph and it was too high so I'm fixing that and cutting back on the nutes and see how it goes 😀
Can anyone tell me what's going on here and how to fix it? I have yellow and brown tips and rusty brown spots on the leaves, plant has been going so well thus far it would be a shame to lose it!
The burned tips are the symptom of overfeeding and dots are the symptoms of a calcium deficiency. There can be 2 reasons for the calcium deficiency. The ph inside the soil is not within the right range or you do simply not give enough calcium. You know which of these problems caused the deficiency the best.
Cut down on the nutrients a bit, make sure that you water with the right pH and add a cal-mag supplement if you did not use one yet.
