Is this from low humidity?

[MammothGrow]

Hi, my room is running at 80.6 degrees F and 30% humidity. I transplanted my clones that were in rockwool cubes straight into the 5 gallon pots. Roots Original soil with some coco fiber on top as a mulch. I've given them one veg feeding using the(Roots Organics Master Feeding Schedule). Transplanted 12 days ago. Watered them in with pure water really heavy, they showed stress till day 5 then started perking up. Watered with veg nutes and topdress about 6 days later. I'ts been 6 days since. Also, notice one plant with a few spider mite bites, so I sprayed all the plants pretty heavily with Azamax. Though they were doing the eagle claw leaf roll before that. It is mainly the Mendo Breath showing what I believe to be heat stress and/or humidity problem. What do ya'll think? Thank you for your time

You are feeding them too soon and it is a little too warm. Try to get your temps down a couple degrees if you can. Just water only for a couple weeks. I don't think humidity is the issue.

You can water a little more frequently until their roots fill out the pot.

Azamax may or may not work with your mites. Applying it too heavy to over fed plants in high heat will burn them up. Mitey Wash is good stuff in my experience.

You think the eagle claw is from mild nitrogen toxicity? That would definitely make sense. As for the temp its mostly 77 degress around the majority of the plants. Only a few spots hitting 80-82 and the co2 is at 1500ppm which ive read at that level 85 is ideal, but i personally think 80 is much better. Definitely got a few burn spots on the leaves after the Azamaxing, white patches looking like light burn and some light brownish, almost resembling mag deficiency. I'm only vegging for maybe 4 more days, otherwise they will get too tall. I usually trigger flower when they are the height they are at and they finish around 3 - 3 1/2 feet tall. Maybe wait to feed after a week into flower? But the master feeding schedule calls for feeding every watering, maybe not follow it to a T?

Overwatering.

my guess is azomax is the culprit plants look stressed a bit give them a week and see what happens and try to bump up the RH its much needed
Humidity controls the rate of transpiration and how the nutrients are received by the plant. Just as with humans, if the humidity gets too low, our skin can become dry and flaky. We transpire by sweating more fluids out in lower humidity levels. The humidity level is like a pressure cap on the plant, keeping the moisture in the plant, allowing it to have proper transpiration rates of the fluids. Ideal humidity levels in a grow room range between 50% to 70% in vegetative growth, and 50% to 60% for flowering plants.

When humidity levels drop too low, the plants transpire at a rate much quicker than that of nutrient uptake. The nutrients or minerals do not transpire thru the plant, only the water does. So this leaves behind a concentrated level of nutrients in the plant that will actually cause a nutrient burn. Most people don’t realize in situations like these that the humidity could be responsible; usually thinking that it is too many nutrients in the reservoir. Just as a lack of CO2 can cause a plant to go dormant, low humidity can cause a plant to have nutrient problems, resulting from the transpiration rate being much too high in low humidity level environments.

I would cool things down about 5 degrees and make sure the soil bags are light before irrigation. A week of pH'd cal-mag would most likely help the leaves from turning yellow. Hope this helps.

Overwatering.

not necessarily if other enviroments were in check i would agree that the issue lies in root system or temps but in this case with real low RH it could very well mean not enough water and a gradual build up of salts eventually leading to burnt roots and plant with the drooping its either over or under watering i am guessing the plant needs more water to nutrient ratio for starters

When I put my girls into the room where they sleep a try to run a humidity as low as possible. However, I only feed my plants 80% strength tops so any concentration of nutrients doesn't turn into a problem. However, what got me this year was heat damage from improper root management during a heat wave... and this dropping looks a bit similar to what I saw in my plants a few weeks ago.

why more Calmag ??? with higher temps comes more plant water uptake i used to grow at what most consider optimum temp range since bumping temps up to 86 - 88 i see improvements accross the board in veg and when in flower as weeks go by i drop my temps with wicked results

this looks like the case where possibly plants were still damp, from treatment and lights came on or recently transplanted but how can a plant be perfectly healthy when there is low RH .. go walk into a botanic garden and look at them plants thats the difference between healthy plant and everything working properly ,, then look at plants with very low VPD growers need to find the equilibrium water in air ratio its more important then lights

I think if the plants were not stressed by the heat.. the low RH would have a minor negative effect on plant metabolism. I don't think as much emphasis needs to be put on low RH... Just zero diff or consistent temperatures when the plants are awake and when they are sleeping. One heat spike could mean weeks worth of recovery for the roots.

I also recommend cal-mag because I use well water.. and I always find watering with straight well water for me help rebound plants with root damage the quickest way possible.

So yeah definitely getting the eagle claw because they are overwatered. Just taking a 6 month break has made me feel like a beginner again lol. Should've been able to figure that one out. Almost watered again with Hygrozyme, but then remembered to go poke and prod a bunch of pots to see how much water was in the soil still. After thorough poking around they definitely were overwatered, going to let them do their thing a few more days and then when they're ready I'll give Hygrozyme with the next watering. Thanks for everyones input
