Anyone knows what this problem is?

temps are 24ºC the bulb is like 25cm away its CFL it isnt crispy the brown was mushy but now it got those yellow marks on the photo and its cryspy. From what i've read, plants leafs have (lets call it "doors") "doors" to exchange CO2 that will help with photosynthesis if it gets lockdown the leaf starts to die and then later the plant, considering this is not the first time i feed plants, and that i fed them with almost no fertilizer, i only gave them nutes because their leafs were getting light green, a very tiny portion of what im used to give, considering this and that this happen like 1 or 2 days after i sprayed them with neem oil and that neem oil locks leafs CO2 intake, by that it locks photosynthesis which will (i dunno) lock the nutes intake and also since CFL emits more UV then HPS and oil (atleast in people) burns faster then anything else. Wouldnt you consider the possibility that this was caused by neem oil? Since this only happen 1 or 2 days after i sprayed them with neem oil?

Thanks for your input!

yeah. neem oil. what are you spraying them with neem for? for mould, for insects?

it's my understanding neem as nutrient needs to go into the soil not onto the leaf.

but if you add neem to the soil as a fert you will imbalance the other nutes you are using.

flush, start again without the neem!!!

you're overthinking this problem, I 'm thinking.

the "doors" are called stoma, stomate, or stomata ( this is like fifth or sixth grade guys). here is a picture of one close up.

(notice the opening for the transfer of air, waster, and nutrients.)

sorry guys i had to

peace,

your way over thinking it plus your incorrect the stoma don't lock anything out if anything, its their jobs to open and shut according to their moisture content and the environment. if they were to stay did open the leaf would dry out and die rapidly like what happens when mites attack since thats what they do is pierce the stoma so it can no longer close and regulate its internal moister it dries and dies.

lockout occurs in the root zone from ph issues and over fertilization

Ive never had a problem spraying neem oil, though i no longer us that any way theres way more, more effective organic products.

its really hard to diagnose a problem through pics especially when we haven'y been able to see the symptoms progress through the plant

might think about starting over

thanks, those pics are much better. you plants are fine, except the one on the right of the centered plant in the first picture. the shorter plant in the water bottle. its too wet. let the soil get really bone dry before you water it next time. it's hard i know but trust me, you will encounter root rot if you don't. those tall containers like that don't drain well and if your mix is too heavy it dries uneven. the roots at the bottom dry out way faster than the ones at the top. you gotta train the roots to only suck water from the bottom. by watering from the bottom probably. im still working on a solution. but i can tell you what will happen since i use tall containers too.

im guessing the neem or whatever you sprayed on your leaves magnified the light or closed the pores and blocked the leaves from transpiring. just go on and cut off all the ones with a lot of damage like the one in the first picture. if most of the leaf is browned or black cut it off in the middle of the petiole (leaf stem) if more than just the tip of any leaf is dry cut the whole leaf off at the petiole. if its just the tips and they are completely bone dry, cut the tip off past the burned part. this will help your plant recover faster as right now it is still working with the broken leaf trying to work around the damage. just causing more stress, it will be easier for the plant to just promote the next leaf to be a fan leaf instead.

good luck, remember let those pots get light before you water again.

wilbur, i was spraying it to avoid bugs.
Infi, sorry but i cant show progress of something that happen in two days one day they were normal the other the leafs were mushy, next day still mushy and the next they were burned like in the last pic. Anyway, i dont remember disrespecting you but thanks for your input.

stihgnobevoli, tks m8 ill do that after drying the soil im gonna get those pot plates. I saw a thread where a guy was drawning the plants on water till the soil stops bubbling, he was saying while the pots were inside the water it would remove the toxins and as he removed them from water, the water would create paths so more O2 would get to the roots and that you would get better drainage after.
