Brown spots and yellowingWhat do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.

Watering and run offUsing Super soil base mix and watering only with ph 6.6-6.8, run off ranged from 9.4-9.7. Lowering PH to 6.35 , run off ranged from 6.98-7.82.

Tissue culture protocol / looking for new media protocol that accounts for clorosis in long term culture for shipping purposesLooking for tissue culture protocol that the plants don’t get clorosis from nutrient depletion. I know I can use temp. Emerson bio reactors and change the nutrient mix during multiplying to deal with the problem. Looking for media that will last in long term cultures for shipping9h ago

White spots on the leaves, what is it?Two of my plants are presenting some white spots on the leaves, as well as yellow on the tip of the bottom leaves (one of them). Should I be worried? I had some cases of mildiou in my tomatoes plant recently and want to act quick if it’s a fungal. Many thanks

Looking for cannabis tissue culture protocol that is adjusted to account for extreme nutritional depletions (multiplication stage fails when they run out)Has anyone tried tissue culture with cannabis yet? Does anyone have a cannabis tissue culture protocol that works? Has anyone solved the problem with nutrition depletion in the media? I’ve heard ppl have had decent results with temporary Emerson bio reactors?12h ago

When should I top, transplant and train my plants?My 2 plants (different strains) are at 5th (Ozz) and 4th (Peppino) node. I plan to top at 4th/5th node, then repot next week (Peppino needs it soon, Ozz maybe later) and start LST a week after. Is this timing OK or will it be too late for training? I need to limit the height

Iron/sulfer/whatever deficiencyIs this a iron/sulfur deficiency?
I just fed it fox farm big bloom with molasses aerated for 24 hours.
Buds are fine. and it’s only got about 2-3 weeks left. Is it worth adding iron.
I’m also wondering if it’s just color change from adding organic nutrients, it happened same day

Temperature issues? Too hot?3 seedlings of Auto Colorado Cookies (i guess because is USA strain, they can resist a bit higher temperatures). Heatwaves here, but in my tent is often 27,5 degrees celcius or a bit more. Is this damaging for the new baby seedlings? With light off mostly 25 - 26 degree...

Watering / light questionHave seedlings here in 5 gallon fabric pot. They just popped up on soil, and one had cotyledon leafs already (the other 2 still have the seed attached.
Give them now 100PPFD light, is this enough?
Also, should I water again when the top is dry, or more fast already?

Cotyledon issue from seedlingHave seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue?
Now I am around 100 PPFD and put the light a bit up. See photo.
