What's that gunk on your leaves? Did you fall for the milk wive's tale? Don't spray your plants with milk.. just end up with rotting shit on your leaves that is more of a disease vector than whatever reason you applied milk.
The leaves look like they are all reaching really hard for light... Probably need more light.
"praying" can be a good sign or a bad sign.. context matters. If you know you are around 30-40 dli, then you can assume it 's not the light intensity. mid to low 20's DLI might pray a bit harder and it will come with excessive stretching of internode too. observe cause and effect to discern which...
foliar sprays are more about making a person feel better about what they are doing more so than any tangible function that should be accomplished by other means 99% of the time. A foliar spray in response to a specific stimulus is fine, but regularly doing it just to do it, is stupid. Some things, like neem, can be preventative measures, but there's no reason to rely on feeding your plant through the stomata -- one, not everyhting can traverse the stomata and two, that's what the damn roots are for and they are WAY better than stomata at doing it.
a need to foliar spray nutes is simply a sign your fertlization is lacking in one way or another. Sure, use a foliar spray for immediate help to an ongoing issue, but also adjust your formula to avoid the foliar spray need in future.
A constantly wet plant every day or often is just a disease vector. Not only that if you have a small infection starting, miss it and spray, you now spread it all around underneat and wherever that water drips. ... kinda like throwing kerosene on a fire... just sped up the infection exponentially.
standing water on the leaves is unnecessary risk and the only benefit is someone's ego. Somem preventative options are out there, but they don't get applied very often -- 7-14 days for neem, for example. this is less of an issue than something you do daily or frequently. Some foliar sprays can be justified. Supplementing fertilization is just a failing of fertilization in substrate. it's a mistake that should be corrected, when it occurs.
