Yellow edges to leaves
stashiostarted grow question 3 years ago
Hello fellow growers. I have noticed some yellow edges to a handful of
her leaves. pH droped a bit today down to 5.6 but has been stable at about 6.4 previously. Photos from the last few days show this problem has been creeping for a couple of days. Any ideas?

Hey there Stashio, basically you have magnesium deficiency . Looks like you're not using dedicated calmag, but really you should, you cant really replace it with silica . Just try adding magnesium if you can , usually if you do this the problem should stop spreading immediately and the plant will recover quite quickly. Hope this helps ! 🚀

Thanks guys I've added 20ml of Vitalink Cal Mag to the 20l sump just to be safe. I'll try not to worry I've just been so lucky i don't want to mess it up now.

As mentioned they look good mate and not far from a Flushing period anyway so I wouldn't worry at the slight discolouration seen.

She just needs some calmag as she's low on calcium, only slightly! Wouldn't fuss about it to much as your close to an end anyway so could also be a sign she's reaching her end

Im wondering if it could be fan related. The yellow leaves are high up in the space and opposite the fan

Being 6 weeks into flowers i personally wouldn't really bother about it.
I grow 8 plants of the same strain at time, and it's not rare i have 1 or 2 phenotype(s) showing similar pattern while all the others don't, my point is sometime some phenotype are a little bit more sensitive to feeding than the others and could show a few burn or deficiencies, but it usually don't spread excessively till the end of flowering so i don't bother about it.
Happy growing

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.
