why are my leaves brown and yellow getting crusty??

idk what is wrong with it she started to do this about a week ago she is two weeks old my other plant is doing fine its very bushy its in the same conditions this one is in and its not having that problem but its not the same strain its slowly working its way up the plant if anyone could tell me what might be wrong it gets enough water i know thats not the problem and my other plant i noticed it had little pink bugs on it any idea what thoes are and how to get rid of them thanks

Magnesium deficiency, likely due to pH lockout as the plants are this young. Transplant it.

Or it's the beginning of nute burn. You're the one watering and feeding.

i have given it no nutes just water its 6.3 not to far off what it should be

i believe it cal/ def mag generaly has purple veins and stem

well today i transplanted them into bigger pots im sure that helps too but what nute should i look for for now im on a budget so im shopping locally like lowes walmart dome depot places like that so if you can let me now

to help give more magnesium an whatever else it needs

How old is it?
It doesn't look like you should be feeding for another couple weeks.

How often are you watering? My first thought was over-watering.

Appears to be cal/mag issue. You say no nutes as of yet, what kind of soil are you in? Most store bought potting soils have nutes in them already. What are you using to water? (Tap, distilled, RO?) Distilled and RO have no minerals in them and will cause cal/mag issues in many cases. try a tbsp of Epsom salts next water and look at the new growth. If those edges are crispy they're gone, but the plant will survive. Lock outs are caused either by pH or an overabundance of another nutrient. I doubt it's that. could be wrong tho........It's been known to happen

i would check your soil, my guess its MG since he said he was on a budget, but who knows. but ya check the soil

Prolly. It's still all good, just water with the epsom and watch the new growth. Should be fine after that. Just give it some Epsom salts every few waterings.

What kind of soil ??

Transplant them into better pots and if the leaves get worse cut them off not all of them but just the ones ur worried about you will be fine.
