Hi this has gone 96 days from seed, about 60 from when I noticed first preflowers no amber trichs at all but majority are cloudy so wondering if I should just chop it or wait for amber? Don’t want it getting too stoney either Most pistils have turned from white Thanks

i don't know - even stranger if your other plant is fine - the leaves with the rust spots also seem really dark green like overfeeding, excess magnesium can also cause a lockout in cases like this i just do a flush of the plant and then start feeding again with about 1/4 strength nutes

it certainly looks like the classic Ca deficiency, maybe the Ca is being locked out ?

Calcium deficiency on the first one, that white stuff on the second could be bugs? not sure

leaves look very green so may be over feeding them, which may lead to a lockout

looks like too much nutes

You would think with the yellowing of leaves below that the plant is not getting enough nutrients but the burnt tips seem to suggest too much - however it seems your leaf margins are just about to start turning brown as well not familiar with these nutes at all so will let someone else comment -...

another thing I've just remember from previous grow - my buddy said the buds "were running" up the colas and this may be a sign of temps being too high, I am seeing this strain do the same thing, big gaps between bud sites on the colas - so reducing light intensity and temp is more than likely...

No I never have them running at full power - usually have the pot around 12 o'clock position but I'm pretty sure the pot does not scale linearly so i don't really know how much power the leds are putting out at this position - I need to hook in my power meter to the plug socket and measure the...

thanks gonna read this now

thanks - think i'm afraid of not giving them enough light

potentially heat stress

hi it's a Meanwell HLG-320

Hi, i think I am providing my plants with too much light, seeing some weird symptoms, I have 6 x CXB3590 in a 75 x 75 x 200cm tent, is there any device to reliably measure the light intensity? I have an adjustable dimmer on the power supply, I have measured the power draw from the wall at about...

I think it could be Light Burn - I do have my plants fairly close to the LEDs https://www.growweedeasy.com/cannabis-plant-problems/light-burn

temps 27-28 C growing in soil under COBs

Anyone know what causes this?? Every single grow no matter what strain I thought maybe it was magnesium deficiency so have been adding some canna mono 1ml/L since the start of this grow but doesn’t seem to make any difference These leaves will eventually die but I’m only 6 weeks into flower

4 hours??

the leaf tip curl there in the last pic looks like a mag deficiency to me, is your pH where it needs to be?
